The indicator shall allow users to "analyse" a recent historical candle to detect whether it was a swing point. This will work by inputting a number to select which historical candle you want to check. The indicator will then check all candles after it until the current candle. It shall also check the same amount of candles before it. If the candle analysed has the lowest low or highest high in the complete range, then we know it was a swing point.
I will let you know I gonna try it!
This indicator can't repaint (only issue prior to v3 of pine script was with the "security" function and/or utilising multiple time frames). Given this is v3 and the security function isn't used = no repainting :)
If it were that easy we'd all be rich ;)
