Screen stocks by custom pattern

Hi,
How can I screen stocks using a custom pattern and not the regular fixed patterns?
Can anyone recommend a website??
Thanks,
J

Hi,

I think I found what I was looking for - PlottingAlpha.com, it allows me to draw any pattern (candles or lines).

Is anyone familiar with this site?

Thank you,


J
