I'd like to post here an issue I had which has been sorted out thanks to Marcin from AB support so that it could help others with same issue.
Issue: no trading arrows are displayed in a chart with ribbon example: Plot(4, "ribbon", colored, styleOwnScale|styleArea|styleNoLabel, -0.5,100); Plot(Close,"Close",bar_kol,styleBar | styleThick ); Solution: the price plot statement must come before the ribbon statement. Thanks again to Marcin Regards, paolo
