Some repainting very likely caused by a statement for buy trades Close[0]>High[1] (which would have to be rewritten to High[0]>High[1] in order to show the true signals what would happen in real time, but would need the source code), You can run the indicator in the strategy tester then compare it to a live chart to see the extent of the repainting for yourself. Despite this, to me the signals are still very decent and one of the best I've seen.
