Can anyone give me the PCF for double and triple bottoms

I don't think I've see what I consider to be a particularly good technique for automatically identifying double/triple top/bottom patterns in TC2000.

You may wish to review the following for information on pattern recognition in TC2000 (focusing on double/triple top and bottom topics).

That said, I personally do not think complex pattern recognition is practical in TC2000 using formulas and Scans.

They are at the very least beyond my abilities to help you create without a specific unambiguous objective definition of what you are attempting to identify. It can't be an I know it when I see it type of definition or be based entirely on an image.

This is true of pattern recognition in general with the exception of fixed size candlestick patterns, which are fairly straightforward as long as the pattern is well defined. The first topic referenced in the post has formulas for candlestick patterns.

The following topic has has Condition Formulas to identify candlestick patterns in TC2000.
