[amibroker] Determining the bar where a signal occurs

["enzo" <herrfrechdax@xxxxxxxx>]

Hi,

I am coding a strategie where buy-signals are depending on a certain 
condition based on MACD(), a condition based on MA() and if a 
calculated trendline has been crossed.

The trendline I calculate is based on the number of the bar, where 
the other conditions will be true. There of 100s of signals.

The code looks like that (where DownTrendLine is a function):

CrossDownTrend=IIf(BuyMACDCond AND BuyMACond,DownTrendline
(flag),False);
Buy=BuyMACDCond AND BuyMACond AND CrossDownTrend;

This is to prevent the calculation of a trendline when one of the 
other conditions is false.

My question is: how can I determine the number of the bar where the 
first two conditions become true?

After some hours of checking AFL-examples and studying many AFL-
functions I cannot figure out how to handle this.

Thank you in advance,
enzo
