VIDYA ProTrend Multi-Tier Profit Strategy

Trend-following strategy using fast and slow VIDYA averages with a Bollinger Band filter. Optional multi-step take profit orders are placed using ATR multiples and percentage targets.

Details

  • Entry Criteria: fast VIDYA above slow VIDYA with price outside Bollinger filter
  • Long/Short: Both
  • Exit Criteria: opposite slope or cross
  • Stops: No
  • Default Values:
    • FastVidyaLength = 10
    • SlowVidyaLength = 30
    • MinSlopeThreshold = 0.05
  • Filters:
    • Category: Trend
    • Direction: Both
    • Indicators: VIDYA, Bollinger Bands, ATR
    • Stops: No
    • Complexity: Advanced
    • Timeframe: Intraday
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
