How It Works: Opening Range Breakout
After session open, the EA measures the initial range and seeks momentum continuation. Breakouts often align with the day’s dominant trend, giving a directional bias. Entries are filtered per index and managed by dynamic trailing to lock gains and reduce give-back.
