Yes that would work, but the way you've written it all 3 bullish or all 3 bearish patterns would have to be true for the same stock before anything is returned.
If you are looking for stocks where any one of the three bullish patterns is true, just change the and's to or's for that section.
[type is stock] and [ [[condition 1 bullish pattern] or [condition 2 bullish pattern] or [condition 3 bullish pattern]] or [[condition 1 bearish pattern] or [condition 2 bearish pattern] or [condition 3 bearish pattern]] ]
this should return stocks meeting any one of the bullish or bearish patterns.
