Subject: Bracket Order Setup in NinjaScript - Handling Fast Market Conditions

[Tradewave]

Hello,

I'm currently working on a NinjaScript strategy and I'm seeking advice on the best approach for setting up a bracket order to handle fast market conditions.

Here's my current approach:

1. In the OnBarUpdate method, when a valid long condition is met, I enter a long position
   
   
2. If the long entry is filled, I set the stop loss and limit orders for the bracket in the OnExecutionUpdate
   
   

The problem I'm facing is that in fast market conditions, the long entry may get filled, but the stop loss or limit orders fail to be placed because the stop loss price, which is referencing the Position.AveragePrice with an Offset, can be above the market. This results in an error like:

Time Category Message 6/7/2024 8:30:01 AM Order Sim101, Stop price can't be changed above the market. affected Order: Sell 1 StopMarket @ 5366.25

The behavior I want to avoid is having a naked long position with no stop order, which is what happening in this edge case.

I would greatly appreciate any insights, suggestions, or alternative approaches to handle this scenario effectively. The goal is to ensure that the stop loss and target orders are always placed, even in fast market conditions, to prevent naked positions.

Thank you in advance for your help!

Hello Tradewave,

If the calculated price for the stop is equal to or above the bid (for a sell stop) or equal to or below the ask (for a buy) stop, you could submit a market order to immediately exit the trade instead of submitting a stop order with an invalid price.

Below is a link to a forum post with suggested sample code.
