Possible to get code for testing typical chart patterns?

It can be head& shoulders,flag, double tops /bottoms etc..

Hello,

these are complex price patterns that are hard to get recognized by some simple set of rules. We do not plan adding some pattern recognition tools in near future but it is on our list. Currently it can be done by extending SQX manually using custom coding though. See https://strategyquant.com/codebase

If you have some ideas you can share

You could train a neural network on the chart patterns and then use the trained network to output a signal when it detects a pattern. If you pre-train it should be possible to use it as a custom indicator to output signals.
