McMillan Volatility Bands w/ Buy & Sell Signals [optstrategist]BACKGROUND
McMillan Volatility Bands are an alternative approach to John Bollinger's "Bollinger Band" study and developed by world-renowned options trader and author Lawrence G. McMillan. Given his background in options trading, it was natural for Lawrence to approach any volatility-based study in the same manner options are priced --using Black-Scholes model. This model of pricing assumes a financial asset's volatility should be measured in percentage change rather than absolute value change.
OVERVIEW
The McMillan Volatility Bands indicator for TradingView will plot the 3 and 4-standard deviation bands around a 20-day moving average. This is how Larry has always used this system. The user can, however, change the standard deviation value as well as the moving average length to their preferred setting. This indicator can be used on any asset and on any timeframe.
Furthermore, the indicator will plot buy and sell signals based on a trading system used by Larry in his flagship newsletter publication The Daily Strategist. The system gives a signal when price closes outside the 4-sigma band and then closes back within the 3-sigma band. That 'signal bar' will be colored red or green for a sell or buy signal setup, respectively.
Finally, an arrow will be plotted on the chart where the system would actually enter the trade. This is determined when price trades a little beyond the extreme of the 'signal bar'. The level by which price has to go beyond the 'signal bar' is an input parameter and can be adjusted by the user. We've chosen the default value of 0.34. This means, the indicator will not give a buy or sell entry until the price moves: 1/3 x beyond the extreme signal bar. This is to prevent getting whipsawed by some setups that never really move in your favor. We've found it successfully removes the less-valuable trade setups.
PARAMETERS
ma_length => length of the moving average that the volatility bands work off of
outside_sigma => standard deviation of outer volatility band
inside_sigma => standard deviation of inner volatility band
entry_trigger_cushion => this refers to the percentage of the signal bar's range. The default value is 0.34. This means price will need to move 1/3 (~34%) of the signal bar's range beyond the high (for a buy) or low (for a sell) of the signal bar to trigger a buy/sell entry. This entry plots the arrow on the chart. We have found requiring this extra move in price eliminates many of the less-desirable signals at the expense of entering the better signals a little later.

Double Bollinger BandThe double bollinger band indicator uses a normal bollinger band with a multitude of 2 and on outer band with a multitude of 3. The indicator shows momentum by the price being stuck between the higher or lower bands. If price is in the middle then it is a neutral zone. The band's moving average is a default of 20 sma but included there are two extra simple moving averages just as extra indicators. This is my first published code and the code is messy; however, it gets the job done nice and simple. (:
Enjoy!
RSPRO TrendIndicatorBased on resistance/support and bollinger band fluctuations this indicator also has filter with x bars after RSI overbought/oversell zones from settings.
Indicator has alerts for LONG(BUY)/SHORT(SELL) signals with green/red squares/triangles. You can setup alerts to use different types of entries.
There are two types of entries and signals: early (usually before trend changes) and main (when trend started to reverse)
Fits for BTC and any altcoins. And any assets. Good for both scalping and position trading (depends on timeframe that you use)
Best use it with big timeframes: 45 and 90min, 2 and 4 hours for position trading.
For scalping 5-30min timeframes are good too.
In Script settings you can specify:
1) RSI period, 14 by default.
2) Show early entries (squares), enabled by defaults.
3) Show main entries (triangles), enabled by defaults.
4) Enable/Disable filter to show main entries only after RSI overbought/oversell regions
Disabled by defaults and RSI is 67 for upper zone and 33 for lower zone.
You can also specify how many bars back before current bar this filter must do. It's 10 by default, you can vary it up to 90.
You can also use only early entries (squares)
Or only main entries (triangles)
Or both (by defaults and i recommend)
This is invite only script. PM me if you want to test it.
Bollinger Band Reversal StudyThis strategy was inspired by ParallaxFX.
This strategy attempts to predict when a price reversal will happen. It uses bollinger bands, stochastics and candle formations.
The idea is that when an indecision candle, such as a doji, crosses outside the bollinger bands, then is followed by another candle that pushed sharply back inside the bands, you have a setup.
These setups are marked with green arrows to go long and red arrows to go short. Wait until the next candle begins before acting. The arrow may come and go as the price fluctuates, so wait until the candle closes.
Another play is when the same setup occurs, but on the middle bollinger band instead of the outer band.
These setups are marked with blue arrows to go long and yellow arrows to go short. Wait until the next candle begins before acting. The arrow may come and go as the price fluctuates, so wait until the candle closes.
Closing can happen a number of ways. You can use a predetermined risk-reward or look to sell when the price reaches another band.
In summary.
Go long when a green or blue arrow appears.
Go Short when a red or yellow arrow appears.
Green arrows show signs of reversal from lower BB.
Blue arrows show signs of reversal from middle BB.
Red arrows show signs of reversal from upper BB.
Yellow arrows show signs of reversal from middle BB.
Wait for candle with arrow to close before taking trade.

Squeeze Momentum Indicator [LazyBear] vX by DGTModified version of Squeeze Momentum Indicator visualizing on Price Chart

Ichimoku ++ public v0.9Description:
The intention of this script is to build/provide a kind of work station / work bench for analysing markets and especially Bitcoin . Another goal is to get maximum market information while maintaining a good chart overview. A chart overloaded with indicators is useless because it obscures the view of the chart as the most important indicator. The chart should be clear and market structure should be easy to see. In addition, some indicator signals can be activated to better assess the quality of signals from the past. The chart environment or the chart context is important for the quality of a signal.
The intention of this script is not to teach someone how to trade or how to use these Indicators but to provide a tool to analyse markets better and to help to draw conclusions of market behaviour in a higher quality.
A general advise:
Use the included indicators and signals in a confluent way to get stoploss, buy and sell entry points. SR clusters can be identified for use in conjunction with fractals as entry and exit pints. My other scripts can also help. Prefer 4 hours, daily and a longer time frame. There is no "Holy Grail" :).
If someone is new to trading you should learn about the indicators first. Definitely learn about Ichimoku Cloud Indicator.
Integrated indicators are:
Ichimoku Cloud and signals
Parabolic SAR and signal
ATR stop
Bollinger Bands
EMA / SMA and background color as signal
Williams Fractals and signal
Puell Multiple signal
(MTF) Bollinger Bands + RE RSIs + Hidden Supports & ResistancesI merged some of my previous written indicators, because a combination of multi-timeframe Bollinger Bands, RE RSI and Resistance/Support levels could help a lot.
Don't forget to add my other useful indicator (Classical SnR) to the chart to maximize your profit!
Price Distance to its MA by DGTPrices high above the moving average (MA) or low below it are likely to be remedied in the future by a reverse price movement as stated in an Article by Denis Alajbeg, Zoran Bubas and Dina Vasic published in International Journal of Economics, Commerce and Management
Here comes a study to indicate the idea of this article, Price Distance to its Moving Averages (P/MA Ratio)
The analysis expressed in the paper indicates that there is a connection between the distance of the prices to moving averages and subsequent returns : portfolios of stocks with lower prices to moving averages generally outperformed portfolios of stocks with higher prices to moving averages. This “overextended” effect is more pronounced when using shorter moving averages of 20 and 50 days, and is especially strong in short-term holding periods like one and two weeks. The highest annual returns are recorded when buying in the range of 0-5% below shorter moving averages of 20/50 days, and 0-10% below longer moving averages of 100/200 days. However, buying very far below almost all moving averages on almost all holding periods produces the lowest returns.
The concept of this study recognizes three different modes of action.
In a clearly established upward trend traders should be buying when prices are near or below the MA line and selling when prices move too far above the MA.
Conversely, in downward trend stocks should be shorted when reaching or going above the moving average and covered when they drop too far below the MA line.
In a sideways movement traders are advised to buy if the price is too low below the moving average and sell when it goes too far above it
Short-term traders can expect to outperform in a one or two week time window if buying stocks with lower prices compared to their 20 and 50 SMA/EMA, one to two-week holding periods is quite high, ranging from 72,09% to 90,61% for the SMA(20, 50) and 85,03% to 87,5% for the EMA(20, 50). The best results for the SMA 20 and 50, on average, are concentrated in the region of 0-5% below the MA for the majority of holding periods. Buying very far below almost all MA in almost all holding periods turns out to be the worst possible option
Candle patterns, momentum could be used in conjunction with this indicator for better results. Try Colored DMI and Ichimoku colored SuperTrend by DGT
Surya_ExitThis is written primarily for intraday exits with aggressive loss control; based on short term momentum + volatilty reversals ... may not be good if you have higher risk reward appetite and want to ride the trend longer
MTF Shifting BBs + Reverse Engineering RSIs Overlay on ChartAnother multi-timeframe indicator presents 3 MTF (each) Bollinger Bands and 3 MTF (each) Reverse Engineering RSI and of course with shifting (left/right) capability.
RERSI in a simple term is the RSI but on the main chart alongside with candles.
There are many adjustable options like:
- Show/Hide each BB
- Show/Hide each MA
- Non-integer BB deviation values
- Positive/Negative shifting values
- Show/Hide each RSI
- Show/Hide each RSI Mid Level
- Adjustable Overbought, Oversold and Mid Levels values
I wrote this after my first script MTFSBB, because it's very useful to have BBs and RSIs together on a chart.
Calculating RERSIs will take some time, so be patient with it and feel free to use it.
Bollinger Bands T3/SMA/EMAThis is Bollinger Bands script with an option to choose three different moving averages. The simple moving average is the original settings used by Mr Bollinger. Exponential is a popular choice as it adds more value to the recent price movements. T3 is a lot faster at adapting to the recent price. Compared to exponential, it gives even more value to the recent prices and furthermore, it is smoother. I use it to polish my True Range scripts.
Another upgrade is the ability to have a different colour of the channel when the baseline moves up or down.
Back to calculation? Is it better to use T3 with Bollinger? My opinion is that it depends on the trader. Both of them give you slightly different information and it is essential to look at the historical behaviour and answer for yourself. Will I use T3 calculation? Well, I built this script to find out if I want to.
Have a great trade!
LIZ TIME DIMENSIONEach hourly foot can display the moving average line for the same period of time in the same color.
The average moving line that you want to see is displayed by time leg, as well as the long-term Bollinger band that should be noticed by the time leg.
1. You can get a lot of useful information at a glance by displaying the moving average line of the long-term and period setting that many traders are aware of.
○ The period setting of the moving average line displayed in each time and foot is not fixed as usual, but changed the period by time and foot, and the moving average line of the same color
is the same.
It is a moving average line of time (for example, an hourly average line and a four-hour average line).Therefore, the market price is always the same even if the time to see changes
You can see it on a scale.It doesn't happen when you look at it in five minutes, but when you look at it in four hours, it looks like a downward trend.
○ The sensitivity of the rate to the moving average line displayed is very high.
You can see how rate moves, such as trends, are determined, and you can see reality in abstract chart moves
I can feel it.Purple 24 hours (one day) moving average line with 1 minute to 4 hours of foot, Green 1 week moving average line with 5 minute to day.
The sensitivity to the Blue Monthly Movement Average Line, which is displayed from 5 mins to 5 weeks, and Red One Year Movement Average Line, which is displayed from 1 hour to 5 weeks,
is very high.
Just look at whether the rates are moving up or down the moving average line and you'll be able to decide what to look for.
○ What is the positional relation between the moving average line of seven (eight in addition to the weekly moving average line) in the short, short, medium, medium, long, and long periods?
To make the direction and intensity of the trend easier to recognize, it is colored between moving averages to be visible as short- and medium-term clouds.
The three clouds changed color to warm rising clouds and cold falling clouds, depending on the relation of the moving averages.
·Strong upward trend rates when all clouds are unified in either upward or downward direction and are arranged in the order of short-term, medium-term or long-term clouds
·The thickness of the clouds is strong, and when the thickness is increased, the trend rate is strong.
·Trendless market when clouds overlap or the colors of the clouds are mixed
• Range price when rates are moving back and forth between clouds
You can visually and intuitively understand the market conditions, such as .
○ Short-term, short-term, medium- and short-term positional relationships will indicate the timing of the entry payment and the direction of the long-short.It's also written.
In conjunction with this, the duration for which the background color should be long changes to light warm color and warm color, and the duration for short changes to light cold and cold
color.
2. The long-term Bollinger band is displayed so that you can trade with the higher time base than the time base you see.
○ You can ride on a long-term trend by detecting and entering the trend occurrence of long-term feet with short-term feet.
Buy high prices, sell low prices, relax your trend-follow-style tears, and enable stress-free entries.
○ A light, transparent gray filter is displayed between the long-term foot Bollinger band ±1σ which sets the period suitable for the time and foot.
I understand that while the rate is moving in this zone (called gray zone), it is difficult to trend and the price range is small, so it should not be taken care of.
Yes, you can use this filter to prevent deception when the volatility is not present, and if you are out of the filter, you can use the above sign.
By trading in accordance, you can invest in trend-follow tiles while avoiding losses in range markets.
○ Bollinger bands generally display six of ±1σ, ±2σ and ±3σ, but in this indicator, two are inside ±1σ and two are outside ±3σ.
We have added a total of four bands.The former sets up early entries and the latter sets up new reverse positions, expecting a market shift from overheating.
for tips on how to
○ Expansion period (expansion period) due to characteristics of the Bollinger band is a period when volatility is big for trade, and a squeeze period
(Shrinking period) I understand that the volatility is small and it is not suitable for trade.Also, it's a squeeze period, but it's not
You can seize investment opportunities by making you expect the timing to move from contraction to expansion and by watching.

(Select short-term clouds, short-term clouds, and ultra-short-term clouds to be used for entry and settlement according to the trade style and the 'dissociation between price and moving average'
which varies depending on the brand, time, and market value.)
。According to the calculation of another indicator (LIZ ADX+DMI), the background has become gray synchronously for a period of inactivity and non-trading.
(In such a period, it is often difficult to follow the trend because the market price is difficult even for lower-level ones, and often it is difficult to follow the trend.)

各時間足で同じ期間の移動平均線が同じ色で表示できます。
時間足によって見たい複数の移動平均線が表示される他、その時間足で意識すべき期間設定された長期ボリンジャーバンドも表示されます。
1.長期間でかつ多くのトレーダーが意識する期間設定の移動平均線が表示される事で
以下の有益な情報を一目で得る事ができます。
○各時間足に表示される移動平均線の期間設定は、通常のように期間を一定にするの ではなく、期間を時間足毎に変え同色の移動平均線は同じ時間の移動平均線
(例えば1時間平均線、4時間平均線というように。)としてあります。
このため、見る時間足が変わっても、相場を常に同じ尺度で眺める事ができます。
「5分足では上昇トレンドに、4時間足では下落トレンドに見える。」
という事が起こりません。
○表示される移動平均線に対するレートの感応度は非常に高く、移動平均線にレ-ト
が差し掛かると抵抗を受け反発したり移動平均線を抜けると、勢いよくトレンドが
発生するなど、レートの動きがどのようにして決まっているかを実感でき、抽象的
だったチャートの動きにリアリティーを感じる事ができます。
特に1分足から4時間足まで表示される紫24時間(1日)移動平均線、5分足から
日足まで表示される緑1週間移動平均線、5分足から週足まで表示される青1ヶ月
移動平均線、1時間足から週足まで表示される赤1年移動平均線に対する感応度は
非常に高く、それぞれの移動平均線の上下どちらでレートが推移しているかを見る
だけで、買い目線売り目線の決定ができます。
○短々期、短期、中短期、中期、中長期、長期、長々期の7本
(週足だけはそれに加え最長期の8本)の移動平均線がどのような位置関係にあるか
によってトレンドの方向と強さが認識しやすいよう移動平均線間に着色し短期雲、
中期雲として意識できるようになっています。
3つの雲は移動平均線の関係によりそれぞれ暖色の上昇雲、寒色の下落雲に色が変わり、
・全ての雲が上昇下落どちらかに統一されで短期雲、中期雲、長期雲という順に並
んでいる時は強い上昇トレンド相場
・雲の傾きがきつく厚みがしっかりしている、厚みが増している時は強いトレンド相場
・雲が重なったり、各雲の色がまちまちの時はトレンドレス相場
・雲と雲の間をレートが行ったり来たりしている時はレンジ相場
など、視覚的直感的に相場の状況が理解できます。
表示が可能な時間足は1分、5分、15分 30分、60分、4時間、1日、1週間(合計8つ)です。
※Makenai Chart Indicator の上位版です。
・200SMA,200SMAを中心バンドとするボリンジャーバンド±3σが各時間足に共通で表示されるようになりました。
・5分15分30分1時間足短期移動平均線の設定を変更し、短期雲がねじれやすくし、決済タイミングを早めました。
・短期雲よりさらに短い、超短期雲・短々期雲を追加し、ジェットコースター相場への対応、早めに利確・損切りしたいトレーダーの要望に対応しました。
(トレードスタイルに応じ、また銘柄・時間足・相場つきによって変わる『価格と移動平均線との解離』に応じ、エントリー・決済に使う短期雲・短々期雲・超短期雲を選択します。)
・別のインジケーター(LIZ ADX+DMI)の計算による、ボラティティーがなくトレードに向かない期間は、同期して背景がグレーになるようになりました。
(LIZ ADX+DMIの詳細はこちらのリンクからご覧になれます。https://jp.tradingview.com/script/AUWqluGM/)
(そのような期間は下位足でも難しい相場つき、レンジやランダム相場になっている事が多いため、トレンドフォローが難しい可能性が高いです。)

Overlay_set by HallyIt is a set of overlay indicators that combine 5 simple moving averages, Bollinger band, and clouds of Ichimoku cloud.
The reason I made this is because I want to make it easier to switch the display of the indicator when trading in a short time.
For example, if you double-click SMA, the setting dialog for this indicator opens. Immediately check the check box of the Bollinger you want to add and close the dialog.
You can quickly switch the display with this feeling and save the amount of mouse movement.
x0xXx0xx0xXx0xx0xXx0xx0xXx0xx0xXx0xx0xXx0xx0xXx0xx0xX
単純移動平均線5本と、ボリンジャー・バンド、一目均衡表の雲を1つにまとめたオーバーレイ系のインジケーターのセットです。
これを作った理由は短い時間でのトレードの際にインジケーターの表示を切り替えるのを楽にしたいからです。
たとえば、SMAをダブルクリックすればこのインジケーターの設定ダイアログが開くのですぐに追加表示したいボリンジャーのチェックボックスにチェックしてダイアログを閉じる。
という感じで素早く表示を切り替えることが出来き、マウスの移動量を節約できます。
Bollinger Bands Reversal setups This strategy is meant to be traded mainly on the Forex market.
It is to be used in ranging markets after having identified both support and resistance. You need to identify those zones manually with your preferred method.
The current script will look for a candle breaking the lower band of the Bollinger bands (20,2) followed by an Engulfing candle for a bullish trade.
For a bearish trade, we are looking for a break of the upper band of the Bollinger Bands (20,2) followed by an Engulfing candle.
A setup is only valid if both the engulfed & engulfing candles break the Bollinger Bands.
Additionally, a trade would be triggered only if the price breaks the low of the Engulfing candle ( bearish ) or the high of that candle ( bullish ).
At the moment, the indicator doesn't show the actual Bollinger Bands to reduce clutter on the chart.
You can add a 20,2 Bollinger Band if you prefer.

BB Monitor IndicatorThis is a basic volatile indicator based in the Bollinger Bands that show the explosive market moves (up/down).
JSE Top 40 Comparative Relative Strength RSI OscillatorThis code is the result of an idea by @MarcoOlivano. The question was that if putting the comparative relative strength as an RSI oscillator would help in understanding the relative strength of the stock to the overall market? As we both trade the JSE I have made the JSE:J200 or Top 40 the basis for comparison. This can be changed in the settings dropdown if you want to compare with the All Share Index (JSE:J201) or other markets such as the S&P.
On the chart above I have included the Comparative Relative Strength as a reference together with the Comparative Relative Strength RSI.
If you use the indicator or adapt it please let me know if it works for you, how you use it and if it has any value.
Fancy Bollinger Bands [BigBitsIO]This script is for a Bollinger Band type indicator with as many features as I can possibly fit into a Bollinger Band type indicator.
Features:
- A single custom moving average serving as the middle band.
- Standard MA inputs.
- MA type.
- MA period.
- MA price.
- MA resolution (time frame).
- Visibility toggle.
- MA Candle Type
- Fancy MA inputs.
- Toggle to show only candles included in the MA calculation ("Highlight inclusion") or display entire MA history.
- Toggle to show a ghost trail when Highlight inclusion is toggled on. Displays a shaded version of past MA history before the inclusion period (as seen on snapshot).
- Toggle to show forecast values for the MA.
- Other inputs related to forecasting:
- Forecast bias. (Neutral forecasts MA if the current price remains the same.)
- Forecast period.
- Forecast magnitude.
- Toggle showing details on the screen
- Toggle the visibility of the fill between the upper and lower bands.
- Toggle to use ATR instead of the standard deviation to calculate the location of the upper and lower bands.
- Custom input for the ATR period.
A couple of quick notes. The label will only show up if toggled on, and will always show above the highest of either the candle high or upper band. The fill colors are based on the level of %B currently on the indicator. Higher levels are green, and brighter green, while lower levels are red and brighter red. The fill is lighter in shadow areas to reflect their status as not being included in the middle band calculation.
