Auto TrendLines [HeWhoMustNotBeNamed]

Trendoscope Wizard Updated   
I started off with the intention of creating script to identify Wolfe wave projection. But, soon ran into problem with loops. Realized drawing wedge is more difficult than drawing converging triangle. Hence, took a step back and started working on wedges and triangle identification. Ended up with a messy output which looked like this.

Had to take another step back and hence decided to make Trendlines detection script and here we are :)

▶ Scan pivots which are in trend. This means, series of pivot Highs or pivot lows either in ascending order or descending order.
▶ Draw trend line between each of the pivots in the trend series. For example, if there are 5 pivot high uptrend pivots, draw mXn lines between each of these points.
▶ Select the trend line which is more accurate or stronger. Accuracy is measured by number of candles/wicks touching the line and number of candles which fall outside the line. Stronger trendlines will touch more candles and pivots with less overflow.
▶ Remove all lines except the most accurate one for each direction.

At any point of time, you will see upto 4 trend lines in this script.

▶ Trendline joining pivot highs in uptrending condition
▶ Trendline joining pivot lows in uptrending condition
▶ Trendline joining pivot highs in downtrending condition
▶ Trendline joining pivot lows in downtrending conditions

The older line will remain until the new one comes through of same type. Hence, you will still be able to see uptrending high and low trend lines for downtrending instruments which are created way back!! Also, new trendlines replace old ones only if they are more stronger (connect to more pivots with less overflow)


Settings are simple.

User can select preferred Zigzag Length and Search Depth. Higher numbers for these two parameters will present longer term trends whereas lower numbers will display shorter ones.
Trend Lines controlls will allow users to enable/disable specific type of trend line, set color and line style to it.

  • regular (Regular OHLC candles)
  • ha (Heikin Ashi Candles)
  • ma (Moving Average Candles)

▶ Historical Trail
Added option to show historical trail of trend lines. Trail will appear as dotted lines with low visibility so that it will not take too much chart space and impact visibility.

▶ Live Stats of nearest trendlines

Live stats are shown for the immediate and nearby trendlines. If the trendline is far away, then it will not be shown. At least two trendlines stats will be shown.
Release Notes:
  • Added last update status to table - which shows how many bars back the trendline was created.
  • Added trend watermark - which shows whether high and low trendlines are in Uptrend, Downtrend, Converging or Diverging Triangles :)

SHIBUSD shows downtrend as nearest two trendlines are both going down.

Whereas DOGEUSD presents converging triangle.
