It appears to me that the built in "Bullish Abandoned Baby" filter is incorrect. I ran the filter and it returned 14 results. In those results, the upper shadow for nearly every doji star on the second day overlapped with the lower shadow on either the first day, the third day, or both. In a few of the results, the second day was more of a long legged doji or a four price doji instead of a star doji.

I have been trying to write a filter that generates a Bullish Abandoned Baby more along the lines of the stricter definition given at candlesticker.com. Below is what I have got so far. The only problem is that I ran a backtest on the filter as far back as StockFetcher would allow me to go and my filter couldn't find anything.

Note that the following are the primary criteria given at candlesticker.com for the Bullish Abandoned Baby which I have tried to incorporate into this filter -

a) First day is a "long" black candlestick
b) Second day is a "star" doji
c) Third day is a white candlestick
d) A gap exists between the low of the first day and the high of the second day
e) A gap exists between the high of the second day and the low of the third day
f) The pattern is found at the bottom of a downtrend

Any suggestions on how to twek this filter will be most appreciated.

SOMETHING I LIKE TO DO WHEN I GET FEW OR NO RESULTS IS CLICK THE DEBUG TAB. WHEN YOU DO, YOU WILL SEE A COLUMN OF %'S TO THE RIGHT. THIS TELLS YOU HOW MUCH EACH LINE AFFECTS YOUR RESULTS. ANY LINE THAT TAKES OUT MORE THAN 50 % OF THE PRECEDING LINE'S %, TRY REMOVING IT UNTIL YOU GET SOME RESULTS TO REVIEW AND MAYBE MAKE SOME ALTERATIONS TO YOUR CODE.

I agree the Abandoned baby is really a morning star with Doji, I was so happy to see your filter, do you have this working yet? I was thinking of a Bullish island and making the middle a Doji, if that would work?
Thank you so much, Neal
