Having multiple instances of this indicator on the same chart causes MT4 to freeze and CPU usage to spike, but only when price starts becoming volatile, anyone know why? The settings I have for it are 50/100/150 close, heiken ashi median, heiken ashi high, all with "change color with OBOS cross", and the OBOS set from +- 230 and +-280. I've also changed the arrow ID for all of them.
