[amibroker] Re: How to extract position in (non time based) array - AFL EXPERTS?

["Mike" <sfclimbers@xxxxxxxxx>]

Try this:

y[1] = 1103;
y[2] = 1107;
y[3] = 1095;
y[4] = 1100;

highestY = Highest(y);
indices = BarIndex();
x = LastValue( ValueWhen( y == highestY, indices ) );

_TRACE("Highest Y is: " + LastValue(highestY));
_TRACE("Last index of highest Y is: " + x);

Keep in mind that although you are creating your own array (y), the length of that array is dictated by the duration of the scan/exploration/backtest/optimization. In other words, if you explore a single bar from the AA window, your code will fail since you require at least 4 bars to populate your array. Also, array indexing is zero based. So, it would be cleaner to have your elements populated starting at [0] instead of [1].
