WMA/LSMA - Simplified CalculationsLots of moving averages are based on a weighted sum, the most common ones being the simple (arithmetic) and linearly weighted moving average. The problems with the weighted sum approach is that when your moving average is a FIR filter then the number of operations increase with higher values of length, and when the weights are based on a complex calculation this number of operations can increase drastically! For the common technical analyst the calculation time of moving averages can be an insignificant factor, even more when using higher time frames, however its always a good practice to seek better performances. The SMA has already a calculation where the number of operations is independent of its length, as such it can be easy to do the same for the linearly weighted moving average (WMA). This post will describe the process toward calculating a simple and efficient WMA which will then be used to provide an efficient calculation of the least squares moving average (LSMA). Carving Impulses Responses Remember that impulses responses fully describe the properties of moving averages, the impulse response of the WMA is a linearly decreasing function, so we'll try to calculate it without using a weighted sum. We first need to use a cumulative sum, the cumulative sum can be described as a summation from the first element of a series to the n th element of the series, where n is the current bar number, one could say that this operation is actually super inefficient, however this is not the case, as a cumulative sum can be calculated recursively as follows: y = y + x The cumulative sum can be described as an amplifier and posses the following impulse response: Once the cumulative sum receive the impulse signal as input the result will always be equal to 1. This will form the basis of our simplified calculation, all we need to do transform this response into a linearly decreasing one. The full process is as follows: Get the impulse response of the cumulative sum Subtract this response from a linearly increasing impulse response of size length Normalize the result such that the sum of the resulting response is equal to 1 We need a linearly increasing response of size length , this can be done by using a running sum of the original cumulative sum response, however we must make sure that the value of this response is 0 when the one of the cumulative sum is first equal to 1. Because the resulting response as a maximum value of length we need to multiply our cumulative sum response with length , then we proceed to subtraction. Finally we need to normalize the result, the sum of a linear sequence of values starting at 1 and ending at n is given by the explicit formula : n(n+1)/2 , which in our case give length*(length+1)/2 , we divide our previous response with this result and we end up with the impulse response of a WMA. This process can be graphically described as follows: We can then replace the impulse function by the closing price in order to get the WMA of the closing price. Advantages And Disadvantages The big advantage of this calculation is its efficiency, in its non functional form (you can see it in the code) the calculation of the WMA only require 9 operations regardless of the value of length against length*2 + 4 for the weighted sum approach, as such both methods are equally efficient in terms of operations as long as the length of a standard WMA is inferior to 3, which is ridiculous, as such our approach is more appropriate. Another advantage is that Pinescript does not allow for series as length arguments in the WMA function, however here we can have a variable length for the WMA. Of course there are disadvantages to this approach, in terms of code we require more variables for the non functional form, which create a lengthier scripts. Another disadvantage is that we can be prone to rounding errors due to the cumulative sum, however they shouldn't be significants in our case. Getting The Least Squares Moving Average The LSMA is one of my favorite moving averages, and it can derived from a linear combination between the WMA and SMA described as follows : 3WMA - 2SMA. Since we proposed an alternative calculation of the WMA we can then calculate the LSMA without even using the SMA, why ? because the SMA can be calculated by computing the changes over length period of the cumulative sum of an input, this result is then divided by length . Remember that the impulse response of a cumulative sum is just a rectangular function, all we need is to truncate it such that only length values of the response are equal to 1, this is done thanks to the change function in Pine. In Summary A more efficient calculations for both the WMA and LSMA have been presented, while this on itself isn't super important you have learned what is the process toward calculating a filter without relying on a weighted sum. This calculation will soon be included in the Pinecoders script allowing series as length argument. Thank you for reading, your interest is always appreciated !

Traffic Light IndicatorThe traffic light indicator is designed to be as simple as possible to avoid the steep learning curve that comes with many other indicators. - A Green Circle indicated the price is likely to go up. - A Red Circle indicates to price is likely to go down. - A Yellow Circle means there's some indecision and you should consider tightening stops or taking profits if you're already in a trade. The circles are derived from the combination of a dozen or so indicators with the goal to simplify trading and declutter the charts. It doesn't need to paired with another indicator but having some simple moving averages and keeping an eye on the volume might help you identify possible take profit areas.

Global Indices Weekly Investment StrategyThis strategy aims to provide the optimal times to buy/sell assets on a long term basis. From my testing it works best on a weekly or monthly time frame. The default values are currently set to work best on Global Indices such as the S&P 500. It is very simple in its core, it uses price historical price action to estimate where in a market cycle the asset is. Then combined with a basic Moving-Average-like baseline and long term trend oscillator to gauge direction, it attempts to find the best time to buy/sell an asset to reduce capital draw-down and maximise future profits. Returns here are based on an account balance and trade sizes of £100,000 with no compounding. Does not take into account exchange fees - 0% commission. Please let me know if you have found any optimal settings for a given market using this strategy; such as all commodities. Or if you have any suggestions on how the strategy could be improved in general.

Function : Know Sure Thing ! (KST)Firstly : Know Sure Thing, or KST , is a momentum oscillator developed by Martin Pring to make rate-of-change readings easier for traders to interpret. In a 1992 Stocks and Commodities article, Mr. Pring referred to the indicator as "Summed Rate of Change ( KST )," but the KST term stuck with technical analysts. The indicator is relatively common among technical analysts preferring momentum oscillators to make decisions. References : Investopedia (www.investopedia.com ) Let's start : Simply : KST : Above point 0 means long position (positive zone), below point 0 (negative zone) means short position. I liked this indicator more than RSI because we can evaluate the breaking points of the channels we draw on the indicator according to the regions. Plus area (positive area), breaking the channel upwards may indicate a very strong rise, and minus area (negative area) the channel downwards may indicate a very strong fall. As a person who is very keen to identify major trends in advance, I like the KST indicator to approach the target quickly and simply. I also find it very successful in terms of divergences. CAUTION : This indicator has been written before many times on TV. I have no effort on it. I saved loads only for variable periods. But I have enough experience to say that you are successful in trends with KST . Nevertheless, do not use it alone, as other promoters may benefit. For example , I divided the standard periods into 4 as in the script. With a correct adaptive period, it has the potential to contribute greatly to accurate moves! You can use with mutable variable periods. Abundant trend lines can be drawn on the indicator and divergences between price and indicator can be sought. Best regards!

Rogers & Satchell Volatility EstimationFirst off, a huge thank you to the following people: theheirophant: www.tradingview.com alexgrover: www.tradingview.com NGBaltic: www.tradingview.com The Rogers & Satchell function is a volatility estimator that outperforms other estimators when the underlying follows a geometric Brownian motion with a drift (historical data mean returns different from zero). As a result, it provides a better volatility estimation when the underlying is trending. However, the Rogers & Satchell estimator does not account for jumps in price (gaps). It assumes no opening jump. The function uses the open, close, high, and low price series in its calculation and it has only one parameter, which is the period to use to estimate the volatility. This script allows you to transform the volatility reading. The intention of this is to be able to compare volatility across different assets and timeframes. Having a relative reading of volatility also allows you to better gauge volatility within the context of current market conditions. For the signal lie I chose a repulsion moving average to remove choppy crossovers of the estimator and the signal. This may have been a mistake, so in the near-future I might update so that the MA can be selected. Let me know if you have any opinions either way. Want to Learn? If you'd like the opportunity to learn Pine but you have difficulty finding resources to guide you, take a look at this rudimentary list: docs.google.com The list will be updated in the future as more people share the resources that have helped, or continue to help, them. Follow me on Twitter to keep up-to-date with the growing list of resources. Suggestions or Questions? Don't even kinda hesitate to forward them to me. My (metaphorical) door is always open.

Multiple MACD RSI simple strategySimple strategy script I've had for a while but looks like I never published. Although it is one of my most simple it seems to have the best profitability. It is pretty rough though. the Stoch RSI has only a little weight to the trade trigger. I'll refine it more over time or you can by all means. Basically the Stoch RSI current K line has to be OVER 40 to trigger a SELL. It has no effect on buy side. The triggers are roughly as follows: Year - since so many assets have gone 2x, 3x, 10x+ since 2013 having a strategy that earns a 500% return from 2013 to now isn't that good if buy-and-holding would have got you 800%. This eliminates some of that noise and makes it a little easier to quickly gauge success. So buy/sell trigger need a value of greater or equal to 2018 (default) MACD 1 - First MACD (short) needs to indicate greater than 0 to buy or less than 0 to sell. MACD 2 - Same as MACD1 but for second MACD set (long) Uptrend - Latest close + high divided by last periods close + high needs to be grater than 1. So if latest is 34.30 close and 34.60 high and previous interval is 34.80 close and 34.82 high, that is 0.99 and will not trigger a buy trade. Downtrend - Same thing but close + low and less than 1. This script/strategy is pretty rough but if there is interest I'll polish it more since it is a pretty solid but simple strategy for most assets.

MTF Deviation - Mtrl_ScientistHi everyone, There are a lot of possible ways to look at markets and find valid patterns. This time, I've looked at how shorter time frames deviate from the overall price consensus. What you're seeing here is a range-bound difference of the lowest time frame from the overall price consensus (baseline), represented as blue line. When lower time frames agree with the baseline, the difference becomes 0. Logically, this difference cannot deviate too much from the baseline, and to quantify that, I've added fib-levels based on a deviation percentage that depends on price volatility and can be adjusted in the settings. How it works: First of all, you need to switch to the 1min time frame to get access to the lowest time frame data. Look at how the blue line follows the support/resistance fib levels. Oversold conditions are usually given by entering the lowest red band, whereas overbought conditions are given by entering the upper red band. However, there are also extreme cases, where the blue line exceeds the set fib levels. In that case, price will reverse with very high likelihood. Alternatively you can also ping-pong between two fib levels for frequent small trades. Note that this indicator doesn't use any security functions to access time frame data. Instead, I found a different way to avoid repainting. At the moment I'm just playing around with this to see how I can improve it. Feedback is very welcome!
