Hi! Thanks! Perhaps some of other indicators that you use place themselves below the Supporta. Its visualization is not transparent and it can hide other objects placed below it. Currently, it attempts to put itself lower than all other objects on the chart but probably this does not always work if other indicators attempt to do the same. I will enforce the placement of Supporta more in the next version. For now, please, try to add Supporta to the chart before all other indicators.
