Hello,
Can some please expain use of loop (if, while etc) expression in AFL?
When do one need to use a loop and when can one just rely on
processing of the array bar-by-bar. I am still learining AFL language
and this area is a bit grey.
I noticed many Stop processing AFL use "for" loop but I don't
understand why.
Also, if I can use this statement toi define EMA;
P = ParamField("Price field",-1);
Periods = Param("Periods", 15, 2, 300, 1, 10 );
Plot( EMA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color",
colorCycle ), ParamStyle("Style") );
why would I try this AFL doc example;
myema[ 0 ] = Close[ 0 ];
for( i = 1; i < BarCount; i++ )
{
myema[ i ] = 0.1 * Close[ i ] + 0.9 * myema[ i - 1 ];
}
This example iterates all bars of close array to calculate
exponential moving average.
Regards
Richard
