Order can't be submitted - the OCO ID xxxx cannot be reused + Buy stop error

[Theghios]

Hello forum,

I have 2 errors combined.
The first being Order can't be submitted - the OCO ID xxxx cannot be reused and the other is Buy stop or buys stop limit order cant be placed below market.

My setup is the following
Calculate.OnBarClose
OnBarUpdate() - used to calculate some conditions
OnMarketData() - used to calculate some other conditions and to enter an order using EnterShort.

I am also using checks to entry an order only once every barclose so there shouldn't be duplicate orders

I do not understand if the errors are causing one another or not. I had Buy stop or buys stop limit order solved in the past by updating to the latest NinjaTrader8 version but the OCO one is new.

Attached you can find a screenshot of the errors and a snippet simulating the logic flow

Thank you!

Hello Theghios, thanks for your post.

It looks like EnterShort("Shorto"); is being called a second time, causing this OCO error. You can confirm this by adding a Print method right before the entry order:

Print("Entering Short");
EnterShort("Shorto");

On each bar, the hasShorted variable is set back to false, so it's definitely possible the strategy will go short, then do it again on the next bar if the entry conditinos are true. You should check the Position object to ensure you are flat before entering:

if(Position.MarketPosition == MarketPosition.Flat)
{
EnterShort("Shorto");
}

For the error: Buy stop or buys stop limit order cant be placed below market.

Resolving the first problem might fix this. It means the stoploss order was placed at an illegal price level which should not happen since your parameter type for the stop is in Tick mode, so it will place the stop and target X amount of ticks away from the entry order. When the first issue is resolved please let me know if you are still getting this error.

Please let me know if I can assist any further.
