Zero-Lag TEMA Crosses Strategy

Zero-lag triple EMA crossover system. Positions use recent highs and lows for stops and risk-reward based targets.

Details

  • Entry Criteria: Fast TEMA crossing slow TEMA.
  • Long/Short: Both directions.
  • Exit Criteria: Stop at recent extreme or target by ratio.
  • Stops: Yes.
  • Default Values:
    • Lookback = 20
    • FastPeriod = 69
    • SlowPeriod = 130
    • RiskReward = 1.5m
    • CandleType = TimeSpan.FromMinutes(5)
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: TEMA
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: Intraday (5m)
    • Seasonality: No
    • Neural Networks: No
    • Divergence: No
    • Risk Level: Medium
