This strategy calculates fast EMA line and slow EMA line and compares the size relationship between the two EMAs to determine the trend direction of the market. It belongs to a simple trend tracking strategy. When the fast EMA crosses above the slow EMA, go long. When the fast EMA crosses below the slow EMA, go short. It is a typical dual EMA golden cross strategy.
The core indicators of this strategy are fast EMA and slow EMA. The fast EMA length is set to 21 periods and the slow EMA length is set to 55 periods. The fast EMA can respond to price changes faster, reflecting the recent short-term trend; the slow EMA responds more slowly to price changes, filtering out some noise and reflecting the medium-to-long term trend.
When the fast EMA crosses above the slow EMA, it indicates that the short-term trend has turned upward and the medium-to-long term trend may have reversed, which is a signal to go long. When the fast EMA crosses below the slow EMA, it indicates that the short-term trend has turned downward and the medium-to-long term trend may have reversed, which is a signal to go short.
By comparing fast and slow EMAs, it captures trend reversal points on two timescales, short-term and medium-to-long term, which is a typical trend tracking strategy.
Risk Management:
This strategy judges trend based on EMA crossovers, which is simple and clear to implement. With ATR-based stops, risks are controllable. Further improvements on stability and profitability can be made through parameter optimization and filtering conditions.
