Neo1898 好像调用exchange.Buy这个执行开单的，都是币本位的单，如何改成下U本位的单子呢，是要自己调用交易所的api下单吗？谢谢！

Neo1898It looks like openlong has a swap contract for the bitcoin, but I don't have ETH in my account, so I got it wrong.

The Little DreamError: Failed due to insufficient balance tag This means that there is a lack of assets.

Neo1898The feeling is that var ret = exchange. IO (("api", "GET", "/api/v5/account/balance", "ccy=USDT") uses the u-bit computing privilege; But the key below, which looks like it's the same as the one in the coin base, how does it turn into the key in the U base?

The grassBTC_USDT is usually U-bit, where U-bit is usually 1 for a coin.
