Filter = Cond1 AND Cond2 AND Cond3 AND Cond4 AND Cond5 AND Cond6 AND
Cond7;
would be ok if you only scanned on the lat bar (n=1). But if you
wanted to scan over the last few intraday bars for a signal then you
would need to use timeframeexpand on the signals
Filter = timeframeexpand Cond1 AND Cond2 AND Cond3 AND Cond4 AND Cond5
AND Cond6 AND Cond7, indaily);
Of course if you are only scanning on daily tyimeframe with no other
timeframes, then you could leave out any timeframe
functions/statements and just set the AA settings periodicity to EOD
b) for defining condition:
ver 1: Cond1=Ref(Close,0) > Ref(EMA(Close,20),0);
ver.2 Cond1= Close > EMA(Close,20);
what version is correct ? ver 2 as ref(c,0) is surplus information
that slows things down. (ok for a couple of small things but if many
excess items slows calculation)
c) no idea
