Hi again

Run this AA on a chart of Caterpiller (NYSE - CAT).

Note the trade signal obtained on 7/14/1998. On this date, Cat prints a 
long bullish-looking candlestick. The Analysis, however, enters me at 
the high of the day and gets me out the same day at the low. So I am 
entered at the close price and stopped out just above the opening price! 
This is all on EOD data, of course, so there is  no chance that my 
conditions were met intra-day and then the price subsequently fell all 
the way back to the open, triggering a stop, then shot back up to the 
days highs again.

Any reason for this in my code?

BTW... for some reason, position size limiting seems to be working on 
this Analysis. I changed the TrailStopAmount value back to a +ve 2 from 
a -ve 2, but I could have sworn that the the AA was getting me into huge 
positions with this same filter before I changed to -ve 2!! :(

(See my last email to this board for a full explanation of this last issue)

 
Thanks, Nik
