Is there any software out there that lets you backtest price action patterns, trendlines etc? Something like Price action lab but with some generic patterns built in ?
Thanks in advance for your reply.

I am using Investor/RT exactly for patterns. Programming those steps show where such patterns
occur. By highlighting the patterns (changing candle color) you can go back in your data and you
see all patterns easily. With some stats you can even count the points made and accumulate them
over a given period.
Some examples you can see in my hivola Dax journal.
More details to the programming can be found in many videos made by Linnsoft.
