3. MetaTrader 5 (MQL5) Indicator (with Mobile Push Notifications)
In MetaEditor 5, create a new Custom Indicator named NYOpenSweepDetector.mq5 and paste the code below. It includes native SendNotification() integration so any M15 sweep immediately pushes the Entry, SL, and TP coordinates to your MT5 mobile app.
