This strategy combines EMA and RSI indicators to identify trend direction and make trading decisions. It goes long when price is above EMA and RSI is below the buy point, and goes short when price is below EMA and RSI is above the sell point. It also uses the relationship between the last two candle closes to determine trend direction for trend trading.
Calculate 200-day EMA as the trend line indicator. EMA responds quickly to price changes and effectively determines trend direction.
Calculate 14-day RSI to judge overbought and oversold conditions. RSI below 50 is considered oversold, while above 50 overbought. Also use the upward or downward trend of RSI to determine entry and exit timing.
Compare the size relationship between the last two candle closes to determine trend direction. Incremental last two closes signal an uptrend, while decremental last two closes signal a downtrend.
When in an uptrend, price above 200-day EMA, and RSI below 50 and rising, a buy signal is generated.
When in a downtrend, price below 200-day EMA, and RSI above 50 and falling, a sell signal is generated.
ATR and highest/lowest prices of last 14 candles are used to calculate stop loss and take profit.
Adopt a trailing stop strategy for risk management.
The combination of two indicators improves accuracy in determining trend direction. EMA judges major trend and RSI&Candle relationship judges local trend and entry/exit timing.
RSI effectively avoids false breakouts. RSI overbought/oversold status avoids unnecessary trades caused by EMA’s lagging.
Trailing stop effectively controls loss caused by occasional large amplitude fluctuations.
Optimized parameter combination enhances robustness.
EMA and RSI are likely to generate incorrect signals in large amplitude sideways markets, which should be avoided.
A too tight stop loss causes frequent stops while a too wide stop loss fails to control loss. ATR parameter should be adjusted properly.
Probability of pullback after breakthrough is high. RSI parameter should be relaxed to avoid missing trends.
Adjust ATR parameter and stop distance to find better stop loss points.
Optimize EMA and RSI parameters to find better parameter combinations.
Add other indicators for filtration, like MACD, Bollinger Bands etc, to improve signal accuracy.
Test parameter differences among different products to further enhance robustness.
Try disabling strategy during specific time periods to avoid wrong signal-prone hours.
The overall strategy is quite stable with steady returns, maximum drawdown and Sharpe ratio. It can be further improved by parameter optimization and stop loss adjustment. Also need to watch out wrong signals during specific market conditions, and avoid them via auxiliary indicators or time filters. This strategy has the potential to become a long-term stable strategy through continuous optimization.

// Release : v6.0
// Description : If the last two closes are in ascending order, the rsi is below 50 and ascending, and the current candle is above 200 ema, then LONG.
// If the last two closes are in descending order, the rsi is above 50 and descending, and the current candle is below 200 ema, then SHORT.
