Hello,
I don't understand AFL code, but your indicator looks like this one
without loop.
//priceOscillator
priceOscillator = EMA( C, 39 ) - EMA( C, 189 ) ;
Plot( 0, "", colorBlack, 4 );
up = IIf( LastValue( priceOscillator ) <= Ref( LastValue(
priceOscillator ), -1 ), 1, 0 );
down = IIf( priceOscillator >= Ref( priceOscillator , -1 ), 0, 1 );
_TRACE( "up = " + up + " down = " + down );
Title = "PriceOscillator - " + Name() + "[PrOsc 39 , 189= " + WriteVal(
priceOscillator, 4.2 ) + "";
Plot(priceOscillator,"",IIf(priceOscillator >=0, colorGreen, colorRed),4);
Best regards
