Fisher Indicator: Price-Range Trend Signals and Repainting

Summary

The Fisher indicator is described as a histogram for identifying trend direction, trend strength, and possible trend changes. Its calculation uses the highest and lowest prices over a lookback period, then transforms the current price’s position within that range. The document says the indicator is implemented without relying on standard MT4 or MT5 indicators and is available on both platforms.

The period controls the lookback used to find the range. A longer period is said to reduce false trend-change signals while increasing lag. The main limitation is repainting: when a new bar arrives, prior values can be recalculated, so historical signals may not match what was visible in real time. The document gives no performance tests, entry or exit rules, or evidence that the signals are profitable. The brief description therefore explains the indicator’s general construction and trade-off, but does not establish how it performs across markets or how it should be combined with risk controls.

Key ideas

• The indicator estimates trend direction and strength from the current price’s position within a recent high-low range.
• A longer lookback is described as reducing false change signals while increasing lag.
• The indicator can recalculate prior bars when a new bar arrives, which can make historical signals differ from live ones.
• The document provides no performance evidence or complete trading rules.
