place order issue

[overstartup]

When i want to have position side. It gives error "{1: Operation failed. }" . But if I sent it to"net" it works fine:

Anybody can help to solve it?

OkexTradeMode trademode = preOrder.OrderMarginMode == MarginMode.Isolated ? OkexTradeMode.Isolated : OkexTradeMode.Cross;
                    OkexMarginMode marginmode = preOrder.OrderMarginMode == MarginMode.Isolated ? OkexMarginMode.Isolated : OkexMarginMode.Cross;
                    OkexOrderSide orderSide = preOrder.Signal == SignalResult.Long ? OkexOrderSide.Buy : OkexOrderSide.Sell;
                    OkexPositionSide positionSide = OkexPositionSide.Net;
                    if (preOrder.Signal != SignalResult.Net)
                    {
                        positionSide = preOrder.Signal == SignalResult.Long ? OkexPositionSide.Long : OkexPositionSide.Short;
                    }

                    var orderResult = api.PlaceOrder(preOrder.Symbol, trademode,
                                                       orderSide, positionSide,
                                                       OkexOrderType.MarketOrder, preOrder.Quantity, currency: "USDT");
