what is the accuracy of the charting tool in PI? means if any patten foam in charts how much that patten could be accurate means bullish engulfing are bearish engulfing, dark cloud are preaching line etc,

Works well!. You could check it for yourself if you have latest Pi beta.

I think it is real time, now I don’t know the unit of accuracy that you are asking. It is pretty fast and real time.
