Williams Accumulation/Distribution Signals and Their Limitations

Summary

Williams Accumulation/Distribution is a cumulative price-based indicator intended to reflect buying or selling pressure. Its value increases by the close-to-low distance when the close rises versus the prior close, decreases by the close-to-high distance when the close falls, and remains unchanged when closes match. The document describes interpreting a rising indicator as accumulation and a falling one as distribution; it also discusses divergence between price extremes and the indicator as a possible signal.

The implemented strategy instead takes direction from the indicator’s sign: positive values lead to long positions and negative values to short positions, with an option to reverse those directions. The published example specifies BTC/USDT futures on hourly bars with 15-minute base data for October 2023, but gives no performance results. The text warns that the indicator can lag, generate frequent or false signals, and mislead around market turns. It suggests combining it with other filters and risk controls before relying on it.

Key ideas

• The indicator accumulates close-to-range changes according to whether the close rose or fell from the previous close.
• Rising and falling indicator values are interpreted as buying and selling pressure, respectively.
• The implemented rules take long positions for positive values and short positions for negative values, with an optional reversal.
• The document discusses price-indicator divergence, although the code’s trading direction uses the indicator’s sign.
• Lag, false signals, and market reversals limit the value of a single-indicator approach.
