Help! Ninjatrader 7 crashes contiunously with strategy running

Hi,

I am testing out a live strategy running on the IB paper trader, but NT crashes continuously with the following errors in windows. The stackoverflow happens most of the time. The IB TWS version i'm using is 927.7.

Hi, unchecking IB as the backup datafeed done the trick thanks for the quick reply. I have another problem with overfills which disconnects the strategy happens quite regularly can you help with this or should i start a new thread?

murfy,

We can go over your overfills in this thread as well.

Some background information on what an overfill is:

An overfill is categorized as when an order returns a "Filled" or "PartFilled" state after the order was already marked for cancellation. The cancel request could have been induced by an explicit CancelOrder() call, from more implicit cancellations like those that occur when another order sharing the same OCO ID is filled, or from things like order expirations.

Generally overfills is a serious issue that can occur when using complex entry conditions that bracket the market in both directions end up with both entries being filled instead of one being cancelled. Overfills can also occur when you place a trade quickly hoping to close a position while a prior order to close the same position already had an in-flight execution.

The exact scenarios in which an overfill can occur is highly dependent on the specific strategy programming. By default, NinjaTrader will protect against overfills by halting the strategy, but there are options in our Unmanaged approach available should you decide to custom program your own overfill handling it is up to you to either prevent overfills from being a possibility in your code or by introducing logic to address overfills should one occur.
