Open Range Breakout by SLA is a customizable multi-session indicator designed for structured intraday trading. It integrates London and US opening ranges with key higher timeframe levels such as Previous Day High (PDH), Previous Day Low (PDL), Previous Week High (PWH), and Previous Month High (PMH) to provide a clear market structure directly on the chart. Users can adjust session times, show or hide specific opening ranges, and configure session highs and lows to focus on relevant levels. The indicator offers a clean visual framework to assist in making breakout decisions. It does not include trade management features like Supertrend, ATR trailing, or automated stop-loss logic. For additional dynamic trend filtering or ATR-based trailing, a complementary tool called SMA Breakout by SLA is available separately. This indicator is intended for traders seeking high-probability intraday setups based on precise session timing and institutional liquidity levels.
