how to edit given afl for multiple time frame

i took these lines of code from http://www.amibroker.com/docs/MTFIndicators.html

Count = 0;
result = 0;

for( i = 5; i <= 360; i = i+5 )
{
TimeFrameSet( i * in1Minute );
m = RSI();
TimeFrameRestore();

m = TimeFrameExpand( m, i * in1Minute );

result = result + IIf( m > 70, 1, IIf( m < 30, -1, 0 ) );
Count++;
}

now i have two conditions A and B.
A=(A1 OR A2) //A is some buy condition with multi indicators
B=(B1 OR B2).// B is some sell condition with multi indicators
what i want is -
result = result + iff( m = A, 1, iff( m = B, -1, 0));
as i am new to amibroker, so please any one help me editing this code according my requirement.
thanks in advance.

I hope you did not miss the warning on top?

THIS ARTICLE IS OUTDATED. IT IS 9 YEARS OLD. SINCE THEN AMIBROKER EVOLVED A LOT. CURRENTLY AMIBROKER SUPPORTS WAY BETTER TOOLS SUCH AS STATIC ARRAY VARIABLES THAT ALLOW DOING MTF INDICATORS WITHOUT USING ADDTOCOMPOSITE/FOREIGN FUNCTIONS.

The concept surely looks attractive.
What are the evolved options available plz.

Thanks

IMHO, the MTF approach mentioned in amibroker site tends to merge specific back to general and I am unable to see any advantage in that. Timeframes are not democratic....

Shortly before I saw your thread, I had started a new thread aimed at exploring the timeframe optimising. Reading thru the site you posted, I am essentially working on the idea they've rejected at the start itself because they do not want to curve fit again and again

Their approach is to detect the repetitiveness of a signal for a given candle across all the chosen time-frames. I don't care so much about the number of generated trades signals but on the quality of the trades and the resulting profit of the trade. Therefore, you could say that I am viewing the problem from its tail. I do expect to have to run the curve-fitting routines at least once every month.
