This strategy uses moving average crossovers to determine price momentum direction, supplemented by golden/death crosses to judge overall trend, to implement trend following.
The strategy uses EMA and SMA crossovers to determine price momentum direction. EMA reacts faster while SMA reacts more steadily. When EMA crosses above SMA, it is judged that the upside momentum is strong, go long. When EMA crosses below SMA, it is judged that the downside momentum is strong, go short.
In addition, the strategy also uses the crossover of fast period SMA and slow period SMA to determine the overall trend direction. When fast SMA crosses above slow SMA, it is a golden cross, indicating the market is in long-term uptrend. When fast SMA crosses below slow SMA, it is a death cross, indicating the market is in long-term downtrend.
The strategy identifies long opportunity when EMA crosses above SMA. If it is a golden cross at this time, it means going long is supported by both short-term momentum and long-term trend, which is a better long timing. If it is a death cross, going long is only supported by short-term momentum and against long-term trend, which is a more risky long timing.
Risks can be reduced by combining other indicators for signal confirmation, optimizing MA periods, or setting stop loss.
Overall, this is a relatively stable and reliable trend following strategy. It considers both short-term price momentum and long-term trend direction, generating trading signals through MA crossovers. Compared to single MA strategies, it has higher reliability by combining dual indicators for confirmation. But as a trend following strategy, its parameter optimization and risk control are very important. It needs repeated testing and tuning to truly realize its potential. With continuous optimizations and improvements, this strategy can become a valuable component of a long-term quantitative investment portfolio.
