The spot order is a success! But the futures order below keeps failing! I don't know what is the reason, please help me

#region
var orderData = await binanceClient.UsdFuturesApi.Trading.PlaceOrderAsync(

This isn't related to the code. Please delete your issue. @cknia

i think the API is somewhat bugged. Seems to be a combo of TIF or params in certain combo wont work.

you can try this. it works for me.....

        OrderSide side = OrderSide.Buy;

            var dd = await client.UsdFuturesApi.Trading.PlaceOrderAsync(order.symbol, side, FuturesOrderType.Market, order.orderqty, null,
                PositionSide.Both, null, null, order.clordid);

if ok, close the issue.
