Wing's Trend Lines - Indicators

Wing’s Trend Lines

This indicator draws up to 12 trend lines, based on previous high/low points. I created it to trade manually with it, but it can also be implemented into a strategy. An old indicator that will work on both 10.2 and 10.3. It could be improved using the new functionalities in 10.3.

Features:

Displays 1-12 trend lines. (Up to 6 lines of support and 6 lines of resistance)
Trend lines are updated automatically, just like a regular indicator.
If you decrease the amount of lines (parameter ‘DisplayedLines’) shown, from 12 to 6 for example, it will prioritize recent trends and not show older trends.
Parameter ‘p’ can be changed to increase or decrease the trend lookback. Big or small trends.
Lines are angled Support and Resistance lines based on RSI high/low points.
How to trade: Price will bounce when approaching a trend line (mean reversion) or go through and continue (breakout). Not all instruments are good to trade with the indicator, but they will be in some timeframes.
Does not display horizontal lines of interest (there’s other indicators for that) unless made up by least two price points.

Note that if you load 10000 bars or more it can take some time to load. Note that it does not draw lines into the future (it could probably be updated to do that). When switching trend it will also create ugly vertical change, but it works like a charm.

If you want to apply the indicator, download it, import it, and right-click your price bars and then add the indicator to your price.

I can answer questions in the comments.

Nice aproach, have you ever try to implement it for patterns recognitions, like double top/bottom?
- Wing • 09/08/2017 #
  Not yet but I plan to.

  Have a look in this Forum, I got something interesting for you… https://www.prorealcode.com/topic/dobule-bottom-or-double-top

Dávid Gyalus • 09/08/2017 #
Dear Wing,

As I am a daytrader, and one of my best friend is a programmer we think your approach of support and resistance lines are really interesting! Thank you for sharing your idea! To be honest, I really would like to try it in another platform I use daily, and my friend said that he will rewrite the code to being able to use on that platform, but we would have one question before we could finish that.

Do we assume correctly that, line t1, t2 etc. are just Y coordinates for the current X value bar, or tick?!

Thank you very much
David
