错误 "symbol" 币安 Api

Question

我正在尝试制作一个简单的交易机器人来在 Binance 上进行交易。

当机器人尝试下订单时，它没有通过，我收到以下错误： “BinanceAPIException：APIError（代码=-1121）：无效符号。”

据我所知，我有正确的以太坊和 USDT 代码。几个小时以来，我一直在努力寻找答案，但找不到任何有用的东西。

提前感谢您的帮助，

请看下面的代码。

错误在这一行 TRADE_SYMBOL = 'ETHUSD'。您需要将其更改为 ETHUSDT

错误 "symbol" 币安 Api

Wrong "symbol" Binance Api

python

bots

binance
