Has anyone developed a personal criteria formula for finding double bottoms or tops? Before I start from scratch I'd like to see what's already out there. Thanks

There really isn't anything similar for complex pattern recognition. Clicking on an indicator and selecting Create Scan Condition only works for the conditions which are built into the program.

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.

Thanks Bruce.

I did find some old stuff on this forum. I'll check it out and review the links you provided. I believe that to create any PFC or Easyscan requires the abily to accuratly define the pattern in terms of what's possible within the PCF writer. If you can't define direction and time and price or percentage then you can't write  an effective PCF. I guess the only issue is, are the tools available after I Idefine my criteria correctly?

The tools are there to calculate things like percent change, change in direction, etc... but if the span of time over which the pattern is not fixed, you would normally need to check for each span of time individually within the formula.
