How to re-adapot strategy position at run time

[ManTrader]

I need to re-adopt position my strategy to current AccountPosition without restarting the strategy.
I use IsAdoptAccountPositionAware and AdoptAccountPosition. Imagine the strategy position is 8 and account position is 8. Now I place an order manually, so the strategy position is 8 and account position is 9. I can detect that by comparing PositionAccount and Position but I don't know how to force the strategy to adopt this new position without restarting it.

Hello ManTrader,

Thank you for your post.

AdoptAccountPosition will only come into play when a strategy is started.

However, in NinjaTrader 8, you can use the AddOn Framework and create a NinjaScript that:

1. Loops through the Account.Orders collection for the account to find active orders
2. Subscribes to Account OrderUpdate events to look for any newly opened orders.
3. Tracks these Orders in the script so they can be changed or cancelled with Account.Change or Account.Cancel

I have included NinjaTrader 8 documentation on these items below if you wish to investigate further.

Please let me know if I can be of further assistance.

Thank you, I see how I can get account events and order updates, but the problem is that ExitLong doesn't work when the strategy position is 0 and account position is 1. How can I force a strategy to adopt the new position at runtime?

Hello ManTrader,

Thank you for your reply.

NinjaScript Strategies are not able to see trades that are placed manually or from another instance of a strategy - the above will only allow you to monitor and cancel externally placed but unfilled orders placed to the account, but you would not be able to close a filled order using ExitLong().

Strategies have their own internal position and are only able to see orders placed through the strategy.

I recommend you have the strategy add a button and when the button is pressed, submit the "manual" entry order from from the strategy itself.

Below is a publicly available link to an example.

You could also use the Addon approach to detect changes to the account and drop using a NinjaScript strategy at all.

Last, here is a link that details strategy position vs account position.
