Three Kilos BTC 15m Strategy

The Three Kilos BTC 15m strategy combines three Triple Exponential Moving Averages (TEMA) with a Supertrend filter. A long position is opened when the middle TEMA crosses above the short TEMA, stays above the slow TEMA, and the Supertrend indicates an uptrend. A short position is opened when the short TEMA crosses above the middle TEMA, remains below the slow TEMA, and the Supertrend shows a downtrend. Fixed percentage take profit and stop loss manage risk.

Details

  • Entry Criteria:
    • Long: TEMA2 crosses above TEMA1, TEMA2 > TEMA3, Supertrend uptrend.
    • Short: TEMA1 crosses above TEMA2, TEMA2 < TEMA3, Supertrend downtrend.
  • Long/Short: Both sides.
  • Exit Criteria:
    • Take profit or stop loss.
  • Stops: 1% take profit and 1% stop loss.
  • Default Values:
    • ShortPeriod = 30
    • LongPeriod = 50
    • Long2Period = 140
    • AtrLength = 10
    • Multiplier = 2
    • TakeProfit = 1%
    • StopLoss = 1%
  • Filters:
    • Category: Trend following
    • Direction: Both
    • Indicators: TEMA, Supertrend, ATR
    • Stops: Take profit and stop loss
    • Complexity: Medium
    • Timeframe: 15m
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
