Gold max pro

I need an MT5 Gold swing indicator inspired by the behaviour/style of Gold Max Pro, but written independently. I do not need the original indicator copied or decompiled.

The indicator should identify major XAUUSD swing highs and swing lows, ignoring small pullbacks.

The most important requirement is non-repainting confirmed signals. Once a BUY or SELL signal has been confirmed and printed on a closed candle, that signal must be permanently locked to that candle. It must never move to another candle, disappear, or change after chart refresh, timeframe change, terminal restart or reconnection.

I understand that locking a swing requires confirmation after the actual high/low. I prefer a slightly later but genuine signal rather than an arrow that looks perfect historically because it moves afterwards.

I also need push notifications when a new confirmed BUY/SELL signal is created, and each swing should alert only once.

Please demonstrate it candle-by-candle in Strategy Tester Visual Mode, not just with historical screenshots.
