[amibroker] *HELP NEEDED* Faster "take only 1st signal of the day" code?

["quexos0" <quexos0@xxxxxxxxxxxx>]

I'm currently using these codes to get auto backtester to buy/sell 
on the first signal generated during the day:

-----------------------------
LongSignal = xxx;
ShortSignal = xxx;

NewDay = DateNum() != Ref(DateNum(),-1);
BuyNum = Cum(LongSignal);
DailyBuyNum = BuyNum - ValueWhen(NewDay,BuyNum);

ShortNum = Cum(ShortSignal);
DailyShortNum = ShortNum - ValueWhen(NewDay,ShortNum);

Buy = LongSignal AND DailyBuyNum == 1 AND DailyShortNum == 1;
Short = ShortSignal AND DailyBuyNum == 1 AND DailyShortNum == 1;
------------------------------

The Cum() function lags my amibroker a lot when used to backtest 
years of data.
Any ideas to optimize these codes?

Is there a shorter way to make amibroker detect signals as they 
happen intra-day and start afresh the next? (Like check for x 
occurrance of a pattern within each day)

Thanks!!!
