PASR Indicator repainting issue in MT4

Hi all, Just a quick question, aplogies if its been covered elsewhere.

I know the current bar in the Parabolic SAR indicator will repaint but the previous closed bar will not repaint? I have been informed that the current bar repaints (correct) but also possibly the 2 previous bars?

Is that correct.

If I did a backtest in MT4 on H4 and used the D timeframe previous closed bar PASR would my results be not corrupted by repainting?

Regards

Provided that PSAR indy is coded correctly, its calculation involves only the current and prior candles, therefore it should NOT 'repaint'.

See here for calculation/construction details.
