CPU utilization

[spenbm01]

Can anyone help me figure out why my CPU utilization for NinjaTrader.exe is consistently running between 40% and 52% with TradeStation?

What is your OS and hardware specs?
When do see this CPU level? All the time or only during specific events?

XP Pro Version 2002 SP2

Pentium(R) 4 CPU 2.60GHz

2.59GHx 1.00 GB of RAM

I see the problem daily. Sometimes NT and TS will open and NT will run at the regular 1% to 5%. Then, all of a sudden, everhthing slows down and I check NT and it's running between 40% and 52% constantly. I have to shut everything down and start over.

This only happens after an ATI function has been called? I suspect that there could be consistent calls to NT from TS? If it is part of your TS script, could you try and isolate the call that causes this?

Sorry, I'm not sure what you are asking. I'm using the NTExternalFeed strategy that NT supplied, if that helps.

Instrument ER2U06 5 min chart. No pattern. I am in Sim mode. It happens sometimes when there is no position open, sometimes when there is an open position.

Thanks

- NT version?
- TS version/build?

Also, please check your Diagnostics settings:
- Tools->Options->check "Show Diagnostics tab"->Ok
- Diagnostcis tab: only "Connect", "Order" and "To file only" should be checked
- Log tab: are there some funny messages?
