Hi,
Your math appears to be faulty, and you are not using the min/max Y axis arguments correctly.
The values to min/max Y should be the lowest value and highest value respectively for the scale with which to plot. If you want your indicator to draw in the lower 20%, then you have to make the minY equal to the HaLow and the maxY to be 5 times the range (HaHigh - HaLow) + HaLow such that the range of the indicator is 1/5th the Y axis range.
Translated to Y axis, this ideally means the lowest visible HaLow and the highest visible HaHigh. However, AmiBroker seems to be setting the Y axis min/max one time only, as opposed to dynamically adjusting the range while scrolling.
Therefore, you can use the all time lowest HaLow and all time highest HaHigh, though this may compress the indicator more than you want.
Play with the following and work from there.
Mike
// Plots second chart in lower 20% of window
PH = 20;
/* Dynamic approach does not seem to work, presumably due to
one time only setting of Y axis high/low
function GetVisibleBarCount() {
lvb = Status("lastvisiblebar");
fvb = Status("firstvisiblebar");
return Min( (Lvb - fvb) + 1, BarCount - fvb );
}
Period = GetVisibleBarCount();
MinValue = LastValue(LLV(HaLow, Period));
MaxValue = LastValue(HHV(HaHigh, Period));
*/
MinValue = LastValue(Lowest(HaLow));
MaxValue = LastValue(Highest(HaHigh));
MinY = MinValue;
MaxY = (100/PH) * (MaxValue - MinValue + 1) + MinValue;
PlotOHLC( HaOpen, HaHigh, HaLow, HaClose,"Heiken-Ashi Candles ", colorBlack, styleCandle|styleOwnScale, MinY, MaxY);
