Shorting Downtrends with Moving Averages and Fibonacci Levels

Summary

This short-only strategy combines exponential moving averages with Fibonacci-style levels derived from a rolling range of the 9- and 55-period averages. Its stated entry condition uses the prior close relative to the calculated upper level together with the 21-period average below the 55-period average. The script plots several retracement and extension levels, though the described entry and exits rely on only some of them. A configurable lookback changes the range used to calculate the levels.

The description frames the approach as taking frequent small losses in pursuit of larger downside moves. It exits profitably when price crosses above the 200-period average while the open position is not losing, and also closes when the prior close exceeds the level labeled 0.764 and the entry condition is absent. The published description says there is no preset stop-loss or take-profit and provides no performance results or validation evidence. Because the rules can enter often and the lookback is user-adjustable, results may depend heavily on asset, timeframe, and parameter choice; the document does not establish robustness.

Key ideas

• The strategy opens short positions when a prior-close condition and a bearish relationship between two moving averages hold.
• Its plotted Fibonacci-style levels are calculated from a rolling range of the 9- and 55-period exponential averages.
• A cross above the 200-period average can close a non-losing short, while a separate level condition can also close it.
• The description gives no performance evidence and notes that users can change the lookback across assets and timeframes.
