SPEARMAN RANK TREND OSCILLATOR Guia de trading

The Spearman Rank Trend Oscillator measures how cleanly recent prices are ordered from oldest to newest. Values near +100 indicate a smooth rising sequence, values near -100 indicate a smooth falling sequence, and values near zero indicate choppy, poorly ranked movement.

What does the indicator show?

• Rank Trend Line: Fast Spearman rank correlation scaled from -100 to 100.
• Signal EMA: Smoothed rank trend used to judge acceleration or fading momentum.
• Rank Bias: Slower rank trend that defines broader directional context.
• Long, Short, and Weakening Markers: Events for trend starts, pullback rejoins, and trend weakening.

Key Settings

• Fast Rank Length: Main window for short-term rank trend detection.
• Bias Rank Length: Slower window used as a directional filter.
• Signal EMA Length: Smooths the fast rank trend.
• Trend Threshold: Level required before a trend start is considered strong enough.
• Pullback Rejoin Level: Level used to detect pullbacks that rejoin the existing bias.

How to use Strategy Parameters (Condition Source)

Within the Strategy Tester module, this oscillator is useful for trend-start entries and pullback continuation filters.

1. Signal Events

• longSignal - Main bullish event from a rank trend start or pullback rejoin.
• shortSignal - Main bearish event from a rank trend start or pullback rejoin.
• bullTrendStart and bearTrendStart - Fresh ranked trend starts.
• bullPullback and bearPullback - Pullback rejoin events in the direction of bias.
• bullWeakening and bearWeakening - Warnings that the current trend is losing rank quality.

Strategy Example: Enter Long when bullPullback is true and bias > 0, which targets continuation after a controlled retracement.

2. Rank Values

• rank - Fast Spearman rank trend from -100 to 100.
• bias - Slower rank trend used as trend direction.
• signal - EMA of the fast rank trend.
• histogram - Difference between rank and signal.

Strategy Example: Avoid trend entries when rank is between -20 and 20, because that usually indicates chop rather than clean directional order.
