I would like to test stocks for the common double bottom ("W") pattern.  I would like for RealCode to test for new lows that are equal, or are within 1% of each other, in a timeframe of four to 25 days of each other.

The following uses a low surrounded by 3 higher lows on both sides to identify a "low". I'm guessing you will probably want to modify the requirements somewhat after looking at the results. Some of the stuff looks pretty good, but having two "lows" within 1% of each other 4 to 25 bars apart also finds quite a few patterns which don't look like a W.

Bruce,

Thank you for coding my request.  As you mention, there are a number of unwanted patterns that also show, so as you recommend, I will need to do some modifying of the requirements, but at least this gets me started.

Again, thanks...

Ed

You're welcome.
