It needs to allow me to trade with more than $1 million.
The only concern you have is only able to trade with more than $1 million in 1 order?
And btw, what kind of bot that? Is that manually operated, like you will enter some trading pairs, amount to trade, type of trade (short/long), etc? And also what kind of trades you are planning? Spot trades? Margin trades?
Try to also to look at Huobi Global (
