AI Grid Strategy

AI Grid Strategy places layered buy and sell orders around the current price. The strategy supports breakout (stop) and counter-trend (limit) approaches. After an order is filled, a take-profit order is automatically placed.

Details

  • Entry Criteria: Price reaches one of the grid levels.
  • Long/Short: Controlled via AllowLong and AllowShort.
  • Exit Criteria: Take profit after fixed distance TakeProfit.
  • Stops: No stop-loss.
  • Default Values:
    • GridSize = 50m
    • GridSteps = 10
    • TakeProfit = 50m
    • AllowLong = true
    • AllowShort = true
    • UseBreakout = true
    • UseCounter = true
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Grid
    • Direction: Both
    • Indicators: None
    • Stops: Take Profit only
    • Complexity: Intermediate
    • Timeframe: Intraday (1m)
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
