Managing the Partially filled order

[nandhumca]

Hi, From my strategy, I want to place 100 order if the criteria met. Also I want to set Profit Target and StopLoss for filled order.
If the order is partially filled (for example 20 contracts) and price moved beyond some price,
1. I want to cancel the order for 80 quantity.
2. I want to place PT and Stop Loss order for partially filled order until the price move beyond my price limit. This is where OnExecutionUpdate triggered multiple time with OrderState.PartFilled.

Please provide some sample or code / api reference for above 2 requirement.

Hello nandhumca,

I'm not aware of a specific sample that contains all of that that but I can reference some more simple examples of using OnExecutionUpdate. You have the correct approach to use OnExecutionUpdate, you would need to monitor the incoming executions to check if it was part filled and the quantity that was filled.

To cancel an order you can use CancelOrder: https://ninjatrader.com/support/help...thod_to_ca.htm

2. I want to place PT and Stop Loss order for partially filled order until the price move beyond my price limit. This is where OnExecutionUpdate triggered multiple time with OrderState.PartFilled.

You can use OnExecutionUpdate to submit profit target/ stop loss orders. How you do that would depend on when you wanted to submit them. If you wanted you could do that based on each partial fil however if you submit them on each partial fill and it continues to fill you would need to continue to update those targets to have them be the correct quantity. You could also monitor for the Cancelled event for the entry, after that was cancelled you could submit the target all at once for the partially filled amount.

In the following link you can find a sample of submitting targets from OnExecutionUpdate and then using a price action (breakeven) to control it later: https://ninjatrader.com/support/help...and_onexec.htm

Thanks Jesse. I will explore the links.

In case of any exception in submitting stop loss or profit target, I want to flatten the position. How to do that ? Similarly I want to handle all the negative scenarios of order. So that I will not ended up with unhandled order. Kindly share your input or share some samples.

My order is in below state (screenshot attached) and I couldn't cancel it manually also.

I am able to catch below error on OnOrderUpdate method. But I couldn't Exit from short/long and cancel my StopLoss and Profit Target Order. am i missing anything ?

if(error == ErrorCode.UnableToChangeOrder){
ExitLong();
ExitShort();
CancelOrder(shortStopOrder);
CancelOrder(shortTargetOrder);
}
}

Hello nandhumca,

For a rejection you would generally need to manually manage the position as the strategy would get disabled. You can make a more advanced strategy that includes rejection handling, you do still need to be around to close the error text boxes when that happens. https://ninjatrader.com/support/help...tsub=rejection

If you get an order stuck on the sim account you would need to reset the sim account to clear the orders. https://ninjatrader.com/support/help...TheAccountsTab

Regarding the code you provided, you cannot call both exits at once. you would need to track what position you are in and call the appropriate method. When cancelling orders you should also wait for confirmation of the cancel before submitting exits, that will prevent an inflight execution where the exit is submitted but the target is filled as well before the cancel. Exit orders are also ignored depending on other factors, you can read about the order handling rules here: https://ninjatrader.com/support/help...antedPositions

Hi , My concern is more about trading on live. If my order stuck in live with cancel pending for long time or no way close it , what to do ?

[NinjaTrader_Jesse]

Hello nandhumca,

Stuck orders are not something which can occur in live trading, that is a item that can happen on the sim account based on various circumstances. The sim account in some cases will need reset to clear orders, with the playback connection you would disconnect/reconnect to do that.

Resetting Sim Accounts to clear Cancel pending certainly works ... but I have explored this in the Forum previously, and it is my belief that this is aberrant behaviour that should be "enhanced". It's a Sim Account, completely within control of the platform. If an Order is Cancelled, it should, of course, go through the Cancel pending state, but should be easily cancelled after that. This is both logical and sensible. Surely this can be fixed by the Development Team? One should not need to completely erase an Account's history simply to clear a condition that should not exist in the first place.

Thanks.
