Hoping someone can help me figure out how to fix the X:Y plotting ratio
on a chart.
For example, if I wanted to find the slope or angle formed by the line
drawn through the Last Close to the Close of Five Bars Ago, that slope
or angle would be very different if I was zoomed into the chart or
zoomed out.
How can I fix the Y scale against the X scale of a chart in my AFL and
make it exact, for the purpose of calculating these angles? I checked
the Users Guide and don't see any obvious parameter or option I can set.
Right now, this is what I have at the top of my AFL to plot the chart:
SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close
%g (%.1f%%) Vol " +WriteVal( V, 1.0 ) +" {VALUES}}", O, H, L, C,
SelectedValue( ROC( C, 1 )) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleThick |
ParamStyle("Style") | GetPriceStyle() );
