1. Suitable only for volatile markets
Grid trading relies on price fluctuations within a range, accumulating profits by buying low and selling high. If the market experiences a one-sided rise or fall, it may lead to 'selling off' assets (one-sided rise) or continuous margin calls (one-sided fall). Therefore, it is necessary to choose targets that fluctuate frequently but have no obvious trend.
2. Set a reasonable price range
A range that is too wide will reduce transaction frequency, while one that is too narrow may lead to fees eroding profits. Adjustments should be made based on the target's volatility and historical price range to ensure that the grid spacing matches the fluctuation amplitude.
2. Parameter Settings and Optimization
1. Number of grids and spacing
Too many grids will reduce single transaction profits, while too few may lead to missed trading opportunities. It is recommended to adjust based on capital, target volatility, such as a fixed amount or percentage (e.g., a 5% price difference per grid).
2. Profit-taking and stop-loss mechanism
Set the highest price as the profit-taking point and enable the stop-loss function in the parameters. If the price breaks through the range, it is necessary to decide whether to close the position or wait for a return, avoiding continuous losses.
3. Capital and position management
Ensure that sufficient funds are reserved to meet continuous margin call needs, avoiding interruptions in strategy due to insufficient funds. For example, the initial investment should cover multiple purchases at the lowest price grid and leave a margin.
3. Selection of Targets
1. High liquidity and strong volatility varieties
Prioritize markets with good liquidity and 24-hour trading (such as cryptocurrencies, mainstream ETFs), avoiding unexecuted orders due to insufficient liquidity.
2. Asset types
Commodities, broad-based index funds, and other targets with relatively stable price centers are more suitable for grid strategies, while individual stocks carry higher black swan risks and should be approached with caution.
3. Avoid targets with overly strong one-sided expectations
For example, stocks or currencies that are in a clearly rising trend may miss long-term gains due to premature liquidation of the strategy.
4. Fee and Cost Control
1. Calculate the erosion of profits by fees
Frequent trading may cause fees to exceed grid profits, ensuring that the price difference per grid is sufficient to cover trading costs (e.g., the price difference per grid should be at least twice the fee).
2. Choose low-fee platforms
Especially in high-frequency trading scenarios, low-rate exchanges or brokers can significantly enhance net profits.
