Fractal Basic Chart Patterns [MyTradingCoder]

2022年5月28日

This script is something that I made a long time ago in my early days of learning Pine. It is not in development anymore but has some unique and impressive utility that will help the community. This script will fractally identify chart patterns(iH&S,H&S,W,M) on any chart and timeframe. Most scripts have limitations that make the user have to adjust various parameters to get the desired result to show up on the chart. Lower input values may show smaller patterns, whereas vise versa, higher input values may show larger patterns, but you never seem to get the best of both worlds with these types of scripts. Some users may appreciate the vast majority of input parameters that most scripts provide, but others like myself may find it restrictive and annoying, as you wont get large patterns AND small patterns simultaneously.

All details needed to understand how to use the script are listed below. I will be creating new and well written scripts in the near future moving forward to help the community as best as I can, and just wanted to make it clear that this particular script is just something that I had on the backburner from a very long time ago, before I was a "Pinescript Maven" :) Enjoy!

Available Patterns:
- W Pattern
- M Pattern
- Head and Shoulders Pattern
- Inverse Head and Shoulder Pattern

Customizable inputs:
- Option to specify minimum bars required to consider a pattern.(Can be helpful if you don't want to see lower timeframe patterns, as some may not look like patterns, but if you drop the timeframe and go to the same time, there will be a pattern there on a lower scale)
- Boolean Inputs to Enable/Disable Certain Patterns

Available Alert Options:
- W Pattern Alert
- M Pattern Alert
- H&S Pattern Alert
- iH&S Pattern Alert


User Manual:
- Patterns will be drawn/detected/finalized on the bar close when the neckline is broken
- Green/Red lines represent the historical structure used to identify each pattern
- Blue dashed lines represent the projected price action based on the pattern completing
- Alerts/Indicator will not repaint(Can use 'once per bar' or 'once per bar close' and behavior will be identical. Code is optimized.)
- May have trouble on assets with daily/weekend time gaps with the projected price action dashed line due to time being used as the xloc. If this becomes a problem, leave a comment below and I will consider bringing this back into development and convert to bar_index as xloc to fix the issue.
- Patterns can be all shapes and sizes, hence the beauty of this indicator
- Leave a comment below for any questions or requests and give the indicator a like if you find it useful
