Graham,
Delete my last phrase, it is wrong, there is nothing we can do.
Any user trendline should be drawn from left to right, else amibroker
can not "see" it.
Try drawing an AB and
Plot(C,"C",1,64);
DL=Study("AB",GetChartID());
Plot(IsTrue(DL),"TRUE",colorWhite,2+styleOwnScale);
If the line is drawn from right to left, the white bars disappear !
Since all the left-handed people have equal rights, an explanation
should be added in the description of this interesting function.
