NY Breakout Strategy

Trades breakouts of the range formed between 13:00 and 13:30 UTC. After the window closes, the strategy enters when price breaks the session high or low, targeting twice the range and placing a stop on the opposite side.

    • First bar after 13:30 UTC closes below the session low -> short.
  • Long/Short: Both sides.
  • Exit Criteria:
    • Profit target at RewardRisk times the range.
    • Stop at the opposite range boundary.
  • Stops: Yes.
  • Default Values:
    • RewardRisk = 2
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
