Breakdown Level Intraday Strategy

Places breakout orders around the previous day's high and low at a specified time. Enters long when price crosses above the high plus a delta and short when price drops below the low minus the delta. Position management includes optional stop loss, take profit, break-even and trailing stop.

Details

  • Entry Criteria:
    • Long: price crosses above previous day's high + Delta
    • Short: price crosses below previous day's low − Delta
  • Long/Short: Both
  • Exit Criteria:
    • Stop loss or take profit reached
    • Trailing stop or break-even adjustment triggers
  • Stops: Points from entry price
  • Default Values:
    • OrderTime = TimeSpan.Zero
    • Delta = 6
    • StopLoss = 120
    • TakeProfit = 90
    • NoLoss = 0
    • Trailing = 0
    • Volume = 1m
  • Filters:
    • Category: Breakout
    • Direction: Both
    • Indicators: None
    • Stops: Yes
    • Complexity: Basic
    • Timeframe: Intraday
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
