Remarks

1. Compatible with exchange.IO("currency", "BTC_USDT") switching method, refer to excahnge.IO.

2. Supports switching trading pairs in the backtesting system. When switching trading pairs in the backtesting system, the quote currency name cannot be changed. For example: BTC_USDT can be switched to LTC_USDT, but cannot be switched to LTC_BTC.

3. After switching to a trading pair that is not initially set on the backtesting page, the amount of the base currency is 0. For example: during backtesting, the initially set trading pair on the backtesting page is BTC_USDT, with 3 BTC and 10000 USDT. When immediately switching to LTC_USDT, after switching, the base currency amount is 0, meaning the LTC amount in the account is 0, and the switched trading pair shares the USDT amount, which remains 10000.
