LO1 is a rules-based London Open breakout system built around a defined overnight range. The strategy measures a 4-hour range ending at 3:34 AM Pacific / 6:34 AM Eastern, then places both long and short breakout brackets at that point. If one side triggers and fails, the system can launch a recoup trade in the opposite direction to recover the loss.
How the system works
First, LO1 measures the overnight consolidation range. That range becomes the breakout box. Once the range window ends, the strategy places bracket orders above and below the box, using a configured entry offset, stop offset, and take-profit ratio. By default, the system can place up to three trade sets in a session, depending on whether the quality filters and session conditions remain valid.
If the first breakout trade wins, the opposing side is cancelled and the session may halt depending on your selected halt mode or Auto Risk Management preset. If the first breakout trade loses, LO1 can activate a recoup trade in the opposite direction. Because TradersPost cannot safely replace and resize the original opposing order in the same instrument during fast markets, LO1 uses YM as a proxy instrument for the extra recoup exposure while leaving the original MYM bracket in place. When the recoup target is hit, the system sends exits to both instruments so everything is flattened cleanly.
Why the recoup trade uses YM
The strategy starts with MYM for the initial bracket orders, but the recoup logic may use YM as a proxy because that approach is more reliable in live automation than cancelling and re-issuing a larger opposing MYM order. This design helps the system catch fast reversals that might otherwise be missed if price runs through the entry while orders are being replaced.
Why the system sometimes does not trade
LO1 does not trade every day. It can skip sessions for several reasons:
- the overnight range is too small or too large
- price is too far from the midpoint when the breakout window begins
- news filters block the session or delay the session start
- spike detection or other range-quality logic disqualifies the setup
- directional filtering removes counter-trend trades in newer versions
This is intentional. LO1 is designed to trade only when the setup meets its statistical criteria, not to force a trade every session. That selectivity is part of the edge.
Auto Risk Management in plain English
Recent versions of LO1 use Auto Risk Management Mode to simplify sizing and daily halt behavior. Instead of manually tuning several interdependent risk settings, you can choose a preset like Conservative, Moderate, Aggressive, or Hail Mary. Each preset automatically sets a known-good combination of sizing logic, halt logic, and risk controls while leaving your Daily Loss Limit, range filters, and news controls in your control.
