@bazear85 Hello @bazear85! As you have commented, the problem is the indicator since we cannot verify the guts of this and possibly some data is crossed from one buffer to another and it produces that error, it is also possible that when performing it tick by tick it does not refresh or repaint and when repainting It causes you flashes, another added problem is that if what is done is tick by tick and you need it, candle by candle the values produce very long decimal numbers and when passing them from "double to integer" it produces those flashes, it has happened to me Many times and the only way was in the indicator to change the type of variable if possible, it is a very common problem in MT4 and MT5 thinks that it is developed for machines with a very basic structure so that it is universal and is not limited to the type from the user's PC. See to obtain the Mql4 of the indicator so that we can verify it. 😉
