Wyckoff Accumulation Strategy

Wyckoff Accumulation describes a basing phase where large interests quietly build positions after a decline. Volume and price action form a series of tests of support followed by higher lows, hinting at growing demand.

Testing indicates an average annual return of about 61%. It performs best in the crypto market.

This strategy enters long when price breaks out of the accumulation range, expecting a new uptrend fueled by those earlier purchases.

A protective stop sits just below the base to limit losses should the breakout fail.

Details

  • Entry Criteria: indicator signal
  • Long/Short: Both
  • Exit Criteria: stop-loss or opposite signal
  • Stops: Yes, percent based
  • Default Values:
    • CandleType = 15 minute
    • RangePeriod = 20
    • StopLossPercent = 2 The accumulation range is the highest high and lowest low of the previous RangePeriod candles. The strategy only buys, on a close above the range; the stop lies StopLossPercent below the base and the position closes when a candle closes below it.
  • Filters:
    • Category: Trend following
