Auto TrendLines [HeWhoMustNotBeNamed]

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 :)

⬜ Process
▶ 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

Settings are simple.
