1. Compatible with exchange.IO("currency", "BTC_USDT") switching method, please refer to {@fun excahnge.IO}.
2. Support switching trading pairs in the backtesting system, the name of the denominated currency cannot be changed when switching trading pairs in the backtesting system. For example: BTC_USDT can be switched to LTC_USDT, not to LTC_BTC.
3. The number of trading currencies is 0 after switching to the trading pair initially set on the non-backtest page. For example, when backtesting the initial trading pair set on the backtest page is BTC_USDT, the number of BTC is 3, the number of USDT is 10000. At this time, switch to LTC_USDT immediately, the number of trading currencies is 0 after switching, i.e. the number of LTC_USDT in the account is 0. That is, the number of LTC in the account is 0, and the switched trading pair shares the number of USDT, which is 10000.
