Thanks. Please let me know if the following is workable.
First, I put this before my BarCount loop, to create variables that get
filled with the last 3 daily closes:
// Get the values of the last 3 Daily Closes
DayChange = DateNum() != Ref(DateNum(),-1);
C1 = ValueWhen(DayChange,C,1);
C2 = ValueWhen(DayChange,C,2);
C3 = ValueWhen(DayChange,C,3);
// Trend Tests
UpTrend = C1 > C2 > C3;
DownTrend = C1 < C2 < C3;
Then inside my BarCount loop, in my one-minute timeframe, I have
something like this:
for (i = start; i < BarCount; i++)
{
.
.
.
if ( UpTrend [i] ) BuySignal[i];
if ( DownTrend [i] ) ShortSignal[i];
The problem is that the AFL is only generating DownTrend signals, even
though the symbol data clearly has just as many UpTrends.
Is my general approach correct? Or is there a flaw in my logic?
I have half the code outside the loop because when I try to put all of
the above sections inside the BarCount loop, AB crashes.

ideas or can someone point me to the right resource?
