Lagging indicators

[Scph]

Good Morning,

I am new to Mql5 trading and have a silly questions:

Is there a way to reduce noise generated by indicators calculating an indicator until BAR is closed? For example, the Parabolic SAR indicator signal can switch above/below price until BAR is fully formed.

Can PSAR be drawn on current BAR but based on previous bars calculations? If I have BAR 0, 1, 2 and so on, PSAR on BAR 1 will be based on BAR 0 (and previous) calculations.

Not quite sure if something like this can be achieved.

regards,

Phil
