Please modify this divergence indicator to not repaint. Instead for every candle print a dot above candle for bearish and below for bullish.

This indicator uses a repainting line over the bars where there is a divergence. 

I need the indicator to instead not repaint. I need a simple dot above the bar for bearish and below the bar for bullish. 

This is exactly what Im looking for but in tradingview. I want the indicator to look and act exactly like tradingview's indicator. 

In MT4 the repainting line is causing me issues when I backtest. It is leaving legacy lines all over my chart. 

Attached is the indicator I need modified

Here is the tradingview code if it helps:
