First, you need to determine how your strategy calculates the order quantity, which can be based on: 1. Quantity of shares 2. Amount of money 3. Percentage
This article elaborates on the points of using "Fixed Order Amount" .
The amount of margin required for a trade depends on your risk tolerance.
Using "BOT | Trend" as an example, In the backtested performance, a fixed "initial capital leveraged by 1x" is used as the order amount for each trade, with a maximum drawdown of 25%, meaning the assets decrease by 25% from the "peak performance point" to the subsequent lowest point (1000 ➡️ 750).
Therefore, there are two key points to note here:
* The amount of margin required should consider “How much risk you can bear? ” Assuming you currently have 1000 to operate "BOT | Trend," and you can tolerate a maximum loss of 500 (-50%), then the total amount of each trade (margin * leverage) can be set as 2000, and so on. Example: Now you have 2000, and you can tolerate a maximum loss of 400 (-20%), then the total amount of each trade (margin * leverage) is 1600.
Practice: Now you have 5000, and you can tolerate a maximum loss of 2000 (-40%), then the total amount of each trade (margin * leverage) is ______ (Hint: What is 25% of 2000?).
* Timing to start running quantitative trading. Running a "trend-following" quantitative trading strategy should not start during a continuous profitable period but rather when the strategy incurs losses (relative low point of equity). This is because for trend strategies, sideways market conditions can cause the strategy to go long at highs and short at lows, resulting in a depletion of funds during this period. Starting during a continuous profitable period is likely to encounter fund depletion right after entering because markets alternate between trending and ranging phases.
