Re: Condition is NOT true

[scheier <scheier@xxxxxxxxx>]

Thought I'd pick up on this thread hoping to get the attention of
those of you so clearly accomplished in Metastock programming.  
Further to my project of trying to transfer to equities trading some
pattern recognition techniques I've been using in futures, here's
what I'm looking for:  

Is there some standard Metastock programming to search large
equities directories for such minor patterns as double-inside days,
flags, pennants, 3 day pullbacks, etc.?   I'm already aware that
there are special software programs for these items from Curtis
Arnold and Kasanjian Research, but I'm wondering if someone is aware
of this already done for Metastock.   

And Phillip, thanks again for the code you sent my way regarding my
Dripping Spout pattern some weeks ago.   Did you seen this pattern
in the April Unleaded Gas chart from Friday?  

thanks in advance...
