[amibroker] Determining the bar where a signal occurs - one step further

["enzo" <herrfrechdax@xxxxxxxx>]

Hello,

I know you guys are very helpful, so I guess when no-one answers, no-
one as a clue. Maybe no-one has a clue what I am asking :-)) 

condition1 is based on MACD and Open
condition2 is based on MA and Open

Buy=condition1 and condition2; will deliver many buying-signals in 
exploration and backtest. To calculate trendlines for every Buy-
signal I got to know the number of the bar where it occurs.

Since I asked the forum the first time I found out by myself that:

BuyCondition=condition1 AND condition2;
OpenAtSignal=ValueWhen( BuyCondition, Open,1);

results in an array "OpenAtSignal" with the relevant price-
infomation. Now I can loop through the array and calculate 
trendlines based on the row-numbers of the array. 
But, this is time consuming, is there a faster way to determine the 
barnumber where signals occurred?

ty,
enzo
