### Overview

This strategy combines MACD, EMA and RSI indicators to implement trend following and reversal trading. It generates buy signals when MACD goes up through signal line and close price is above EMA; and sell signals when MACD falls below signal line and close price is below EMA to capture trends. Meanwhile, it trades reversals when RSI reaches overbought or oversold levels.

### Strategy Logic

1. Calculate MACD diffs and EMA.

``````fastMA = ema(close, fast)
slowMA = ema(close, slow)
macd = fastMA - slowMA
signal = sma(macd, 9)
ema = ema(close, input(200))
``````
2. Generate buy signal: MACD diff (macd - signal) goes above 0 and close price is above EMA.

``````delta = macd - signal
buy_entry= close>ema and delta > 0
``````
3. Generate sell signal: MACD diff goes below 0 and close price is below EMA.

``````sell_entry = close<ema and delta<0
``````
4. Trade reversals when RSI reaches overbought or oversold levels.

``````if (rsi > 70 or rsi < 30)
reversal := true
``````

1. Combine trend following and reversal trading to profit from both trends and reversals.
2. Use MACD to judge trend directions and avoid false breakouts.
3. Filter noise with EMA.
4. Enhance profitability with RSI for reversal trades.

### Risk Analysis

1. Reversal trades may incur losses in strong trending markets.
2. Improper parameter tuning may increase trading frequency and slippage costs.
3. Reversal signals may have some lag, missing best entry prices.

Solutions:

1. Optimize parameters to find best combination.
2. Adjust reversal RSI thresholds properly.
3. Consider adding stop loss to control losses.

### Optimization Directions

1. Test EMA lengths.
2. Optimize MACD parameters.
3. Test different RSI reversal thresholds.
4. Consider combining with other indicators.

### Summary

This strategy combines MACD, EMA and RSI to organically implement trend following and reversal trading. MACD judges trend directions, EMA filters noise, and RSI captures reversal points. Such multi-indicator combination can better determine market movements, improving profitability while reducing false signals. Parameter optimization and stop loss management could be further improved to reduce unnecessary losses. Overall, this is a solid strategy framework with potential for steady profits.
