This article explains in detail a quantitative trading strategy that utilizes multi-period RSI indicators to identify reversal points. It analyzes multiple RSI indicators simultaneously to spot market turning points.

I. Strategy Logic

The strategy employs 3 groups of RSI indicators with different parameters:

  1. Calculate RSI values for period 2, 7, and 14 respectively.

  2. When RSI-2 is below 10, RSI-7 below 20, and RSI-14 below 30, a bottom is identified.

  3. When RSI-2 is above 90, RSI-7 above 80, and RSI-14 above 70, a top is identified.

  4. Generate buy/sell signals based on RSI unanimity.

  5. Preset adjustable parameters for indicator consensus, controlling signal frequency.

By analyzing RSI indicators across periods collectively, reversal point accuracy can be improved.

II. Advantages of the Strategy

The biggest advantage is using multiple timeframe RSI analysis improves identification of key points and filters out false signals.

Another advantage is the flexibility to adjust consensus parameters and adapt to different market environments.

Lastly, the RSI combinations also provide more tuning options.

III. Potential Risks

However, the following risks exist:

Firstly, RSI itself has inherent lag in identifying reversals.

Secondly, multiple indicators introduce signal ambiguity requiring clear rules.

Finally, reversal trades have a failure rate requiring psychological preparation.

IV. Summary

In summary, this article has explained a quantitative strategy of identifying reversals based on multi-period RSI analysis. It improves recognition of market turning points by judging RSI unanimity. But risks like lagging and wrong signals need to be managed. Overall it provides a flexible RSI strategy optimization approach.
