Overview

The Fast RSI Reversal Trading Strategy generates trading signals by combining Fast RSI indicator, candlestick body filter, min/max price filter and SMA filter to determine trend reversal points for low-risk reversal trading. The strategy aims to capture short-term reversal opportunities.

Strategy Logic

The strategy is mainly based on the following indicators for judgement:

  1. Fast RSI Indicator: Calculates RSI using RMA function to make it more sensitive in order to capture overbought/oversold signals faster.

  2. Candlestick Body Filter: Requires candlestick body size to exceed 1/5 of EMA body average to filter low volatility situations.

  3. Min/Max Price Filter: Judges if price reaches new high or new low to confirm trend reversal.

  4. SMA Filter: Requires price to break SMA line for additional confirmation.

Trading signals are generated when multiple conditions above trigger simultaneously. The specific logic is:

Long entry: Fast RSI below oversold level AND Candle body > 1/5 of EMA body AND Min price breakout AND Price crosses above SMA

Short entry: Fast RSI above overbought level AND Candle body > 1/5 of EMA body AND Max price breakout AND Price crosses below SMA

Exit: Fast RSI back to normal range

Advantages

The strategy has the following advantages:

  1. Captures volatility from short-term reversals
  2. Fast RSI indicator is sensitive
  3. Multiple filters reduce false signals
  4. Controllable risk, small drawdown

Risks and Optimization

The strategy also has some risks:

  1. Failed reversal risk
  2. Limited optimization space

Can further optimize by:

  1. Add trading volume filter
  2. Implement stop loss
  3. Optimize parameter combination

Conclusion

Overall this is a low-risk short-term mean reversal trading strategy. It identifies trading signals with Fast RSI and uses multiple filters to reduce false signals, achieving controllable risk reversal trading. The strategy can be further optimized and has great potential.
