5 EMA No-Touch Breakout Strategy

The 5 EMA No-Touch Breakout strategy waits for a candle that remains entirely on one side of the 5-period EMA. When price later breaks the extreme of that setup candle, the strategy enters in the breakout direction. The stop-loss is placed at the opposite extreme and the take-profit is set at a multiple of the risk.

Details

  • Entry Criteria:
    • Candle high below EMA → prepare long; enter when price breaks above that candle's high.
    • Candle low above EMA → prepare short; enter when price breaks below that candle's low.
  • Long/Short: Both.
  • Exit Criteria:
    • Stop at setup candle extreme.
    • Target at RewardRisk × risk.
  • Stops: Yes.
  • Default Values:
    • EmaPeriod = 5
    • RewardRisk = 3.0
  • Filters:
    • Category: Breakout
    • Direction: Long/Short
    • Indicators: EMA
    • Stops: Yes
    • Complexity: Low
    • Timeframe: 5-minute
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
