Color Stochastic NR Strategy

This strategy trades using a Stochastic oscillator with several selectable modes. Each mode defines how the %K and %D lines are interpreted to generate buy and sell signals.

Modes:

  • Breakdown – long when %K crosses above the 50 level, short when it falls below.
  • OscTwist – reacts to direction changes of %K.
  • SignalTwist – reacts to direction changes of %D.
  • OscDisposition – long when %K crosses above %D, short when it crosses below.
  • SignalBreakdown – trades when %D crosses the 50 level.

Opposite signals close existing positions and open new ones in the opposite direction. Risk control is handled by fixed percentage stop-loss and take-profit levels.

Details

  • Entry Criteria:
    • Long: Depends on selected mode, see above.
    • Short: Depends on selected mode, see above.
  • Long/Short: Both.
  • Exit Criteria: Opposite signal or stop protection.
  • Stops: Yes, StopLossPercent and TakeProfitPercent.
  • Default Values:
    • KPeriod = 5
    • DPeriod = 3
    • Mode = OscDisposition
    • StopLossPercent = 2
    • TakeProfitPercent = 2
    • CandleType = 4 hour
  • Filters:
    • Category: Oscillator
    • Direction: Both
    • Indicators: Stochastic
    • Stops: Yes
    • Complexity: Intermediate
    • Timeframe: 4H
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
