Disliked{quote} How do I know if the PA is failing like there's no way to make it as an universal rule if you know what i mean... I know all the details about BBMA or at least i think I doIgnored
I find that a retrace happens very quickly. In 1-3 bars and price has changed direction. Generally a reversal is slower. You get a retrace and then price takes another run towards the outer BB but doesnt make it. Then you have a reversal. I watch the H1 charts which make it fairly clear.
If I am not sure I will wait on a close through the 20ma (centre BB)
