哪个大佬帮我看看代码哪里出问题了
我用python写的，想持仓量大于0的时候进行平仓操作,然后回测的时候报错了，显示这个raceback (most recent call last): File "<string>", line 1606, in Run File "<string>", line 57, in <module> File "<string>", line 20, in main TypeError: 'NoneType' object is not subscriptable
amount = 2
if exchange.GetPosition()['Amount'] > 0 ：
exchange.Buy(-1,amount) #买入平空
