Wing's Trend Line Bands - (Support and Resistance) - Indicators

Wing’s Trend Line Bands – (Support and Resistance)

This is an unconventional indicator I have created in PRT 10.2. I have not seen anything similar.

It calculates twelve different trend lines, six that resemble levels of support and six that resemble levels of resistance. They are then averaged into two trend lines, to form a band around the price. The ‘band’ does not behave like for example a bollinger band. Trend Line Bands are more dynamic since they are drawn between different high/low points, and are therefore, straight.

How to trade:

Appropriate timeframe, security and system is for you to find. Remember that this indicator is experimental and can be developed in many ways. Trend Line Bands can be traded in at least three ways that I have found:

Mean reversion (price bouncing on the bands)
Breakout (decisive move through a band)

Band convergence (The algorithm can output a line of support ABOVE the line of resistance. This is a sign of upcoming trend reversal and should not be traded in the ways mentioned above.)

Hello Wing, nice to see your name into the Library too 🙂 I appreciate your help on forums!
I need to investigate more into your interesting indicator, I think I might need some time to perfectly understand the concept behind its code. Thanks for the contribution, I’m looking forward for more interesting things from your own research 🙂

Wing • 01/29/2017 #
Yes, investigate as much as you want. For more insight, you can view the linet1, linet2 etc. individually on the chart. That will show you exactly what trend lines are found and used for the bands.

CKW • 01/29/2017 #
Hi Wing,
Thanks for your sharing. I am still trying to breakdown & understand your code.
For your example above, 30m chart & Parameter = 7. Does it mean this indicator analysze the Support & Resistance for the last 7 candles? (e.g. 4 hours?)
Br, CKW
- Wing • 01/29/2017 #
  Hello CKW.
  No, the parameter, 7 in this case, is used when calling the RSI indicator to identify points of interests. It is between these these points that the trend lines are drawn. There are 8 points in total on which the lines are based, and when a new point is found, the oldest previous point is discarded. New points are found only when the RSI[7] hits an extreme low or high, so the distance between points will vary. If you increase the parameter from 7 to 9 for example, you will experience trend lines that are based on more long-term trends.
