when are old orders got removed?

[clearpicks]

What is the rule that old orders get removed and no longer shown in Account.Orders? Are the rules different in the cases of simulated accounts, simulated connections, real account, real connection, etc.?

Hello Clearpicks,

Thank you for your note.

Sim101 trades while connected to a live connection would stay in the database and can be searched for in Trade Performance via Control Center>New Trade Performance. Trades executed with your broker would also be saved here as well.

No trades are saved when connected to the simulated data feed.

Please let us know if you need further assistance.

Hi Alan,

Thanks for response.

I still don't fully understand the rules deciding in what situation an order would appear in Account.Orders. If the account is real (not sim101) and data connection is real, what are the oldest orders would appear in Account.Orders? are the rules different for different brokers? In the case of realtime real data connection but sim101, what are the rules then? In the case of simulated datafeed and sim101 account, what are the rules?

Thanks,

Hello clearpicks,

Trades made on the platform, either Sim101 or a real account, regardless of broker or data provider, are going to be stored locally on the database and will remain unless cleared by the user.

Above does not vary with different brokers.

No trades will be stored locally if connected to the simulated data feed.

Please let us know if you need further assistance.

Alan,

In such case, can I assume the number of orders shown in Account.Orders would increase indefinitely as long as new orders are generated each day? Is there a way to purge old orders which have been in final state for quite a long time (e.g more than 10 days)? Or is there a specific API to delete certain orders from the database?

Hello Clearpicks,

Yes, account orders would grow over time as additional trades were made.

There would be no supported way to delete trades in the database without clearing all trade history.

Please let us know if you need further assistance.

Alan,

It seems Tools -> Database Management -> Reset DB -> Reset Historical orders and Historical executions is the only way to delete old orders/executions. In case of connecting to a real trading account (e.g. InteractiveBrokers) , does NT try to get synchronized with IB TWS by retrieving historical orders? I assume NT would at least retrieve active orders and positions.

Thanks,

Hello clearpicks,

NinjaTrader does not pull historical IB trades into the database.

Please let us know if you need further assistance.

You can manually delete historical executions one at a time from the database.

Trade Performance > Executions > Right click execution > Remove Execution

To see it removed, you will have to generate the performance results again. To see it on the chart, you will have to Reload Historical Data on the chart.

However, this will NOT adjust the simulated account balance. It will only affect Trade Performance results.

For a live account, I don't understand why you'd want to remove trades.

There are many orders shown in the "Orders" tab in control center as well as in strategy.Orders. I would like to view the most recent or only open orders..

Hello Clearpicks,

You could right click in the orders tab and select a filter, for example active orders. Please see the following section of our helpguide,
