Simple MA ADX EA

Strategy combining an EMA with the Average Directional Index to confirm trend strength.

It buys when the EMA is rising, the previous close is above the EMA, ADX exceeds a threshold and +DI is greater than -DI. It sells when the opposite conditions appear. Stop-loss and take-profit levels manage risk.

Details

  • Entry Criteria: EMA direction, price vs EMA, ADX, +DI/-DI.
  • Long/Short: Both directions.
  • Exit Criteria: Opposite signal or protection orders.
  • Stops: Yes.
  • Default Values:
    • AdxPeriod = 8
    • MaPeriod = 8
    • AdxThreshold = 22m
    • StopLoss = 30m
    • TakeProfit = 100m
    • Volume = 0.1m
    • CandleType = TimeSpan.FromMinutes(1)
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: EMA, ADX
    • Stops: Yes
    • Complexity: Basic
    • Timeframe: Intraday (1m)
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
