This strategy calculates moving averages of different periods and issues trading signals when the shorter period moving average crosses over or crosses below the longer period moving average. It belongs to the typical moving average crossover system. The strategy supports both long and short positions to achieve two-way trading.
The strategy judges market trends and generates trading signals based on the crossover between moving averages of different periods. It uses three moving average lines of 8-period, 13-period and 21-period, where the 8-period line is the shorter period line and the 21-period line is the longer period line. A long signal is triggered when the 8-period line crosses over the 21-period line. A short signal is triggered when the 8-period line crosses below the 21-period line.
In actual trading execution, the strategy also includes a filtering condition to avoid being trapped in choppy markets. It only places orders when the closing price is higher (long signal) or lower (short signal) than the crossover point. This can effectively filter out some false signals.
The strategy has a clear logic of using simple moving average crossover to determine relationships between short-term and long-term trends and capture rotation opportunities. It supports two-way trading and is easy to understand and optimize. But some risks exist like ineffective handling of specific market conditions and lack of risk control. Subsequent technical indicator combos and parameter optimization can further improve strategy stability and profitability.
