Adapting EMA Smoothing with Normalized Average True Range

Summary

The document describes an adaptive exponential moving average whose smoothing factor changes with normalized average true range. It calculates ATR over the chosen EMA period, compares the current ATR with its recent minimum and maximum, and uses that relative position to adjust the EMA coefficient. The intended idea is to make the moving average respond at different rates as volatility changes, rather than use a fixed smoothing rate.

The page supplies an indicator implementation and identifies a period setting, but gives no chart, worked market example, comparison with a conventional EMA, or performance results. It does not discuss parameter selection or safeguards for cases where the recent ATR range is zero, which would make the normalization denominator problematic. The description is therefore a construction outline for an indicator, not evidence that the adaptive version improves signals or trading outcomes.

Key ideas

• The indicator varies EMA smoothing according to ATR's position within its recent range.
• ATR is calculated over the selected EMA period and normalized using recent extrema.
• The resulting volatility measure adjusts the EMA coefficient from bar to bar.
• The document provides implementation details but no tests or evidence of trading benefit.
• A zero recent ATR range is not addressed in the described normalization.
