Perhaps this was a design flaw in the orig indicator, but looks like there might be a repainting issue:

From your pic I see what you mean however trading an H1 or longer after the close of the candle I do not see this repainting. You will notice that when looking at the dots color there are breaks by a few candles and then the trend may continue. I use this as the signal in my system compared to a condition with a trend indicator. Maybe compare a short term and long term nonlagdot system? That would be an interesting EA.

I just realized, an MTF Nonlagdot would be amazing. Is this possible?

Is there any way to make a strategy based on this indicator?

Buy after first blue dot and sell after first red dot.

Use parameter "Period" for other TF:

Can you do a strategy with NonLagDot in agreement with Parabolic SAR where the dot is the signal and SAR sets trend agreement?
