Hi,
Without going into your code I suspect that you might need to use
additional brackets "(" and ")" to group the conditions together.
There are many types of Morning Star candles as per
http://www.hotcandlestick.com/candles.htm
Scroll down to bullish section and you will see Bullish Abandoned
Baby, Bullish Morning Doji Star, and Bullish Morning Star.
If it is the Bullish Morning Star that you are trying to scan for the
definition (per this site) is:
1. 1st day is a long black day.
2. 2nd day gaps below the 1st day's close.
3. 3rd day is a long white day.
So creating a set of logic for each of these 3 conditions and then use
Buy = Condition 1 AND Condition 2 AND Condition 3 may make it easier
for you to debug and test your code.
Here is a exploration that I use for a basis of testing. Run the code
and then look at the parameter options and the output results. This
could give you the basis for testing the 3 conditions above like I
have for a Volume Spike.
Good Luck,
Dave

// Purpose of this code is look for various conditions/patterns or
combinations of conditions/patterns
// The code is a base from which to add, delete, or modify these
conditions or patterns to look for
// A neat feature provided by AB over that of TC2005 is that one can
specify a date range in the past in which to run an exploration
// I can run an exploration for dates well in the past and visually
see how those signals performed (visually as well as via the output)
