How to harmonize external events and an automated strategy ?

[elirion]

Scenario:.
1) Entered 1 x long /ES contract at 5000, bracket orders at 5005 and 4995.
2) Broker daily loss limit: $100 more to go
3) Price goes to 4998, account is down $100 and hit the daily loss limit. Broker issues a cancel all orders and flatten. Account goes into liquidation mode (unable to trade anymore).
4) To the Ninjascript strategy, the position size is still 1 x long when the actual value should be 0. Events from #3 does not update this value within the strategy.

What is a good way to deal with this discrepancy ? Should I try to listen to event from #3 and exit my strategy straight away ? The broker I am using is Tradovate if that is helpful.

Hello elirion,

Any orders that are not made by the strategy instance will not be seen by the strategy and will not effect the strategy position.

If the strategy and account are long, and the account has a sell order, this would make the strategy position and account position no longer in sync.

You can place manual orders to the account so that the account position will match the strategy position.

Or you can disable the strategy, flatten the account, and re-enable the strategy using the Wait Until Flat Start Behavior.

Thanks for your advice Chelsea.

I guess there is no way to automatically manage this part without human intervention.
