There is an unsupported (don't even think about asking for help) hack for Ninja 6.5 if you are constantly running out of memory due to the .NET memory limitations (Ninja crashes around 1.5GB of memory use).
The hack requires:
- Expert technical knowledge
- Visual Studio installed
- x64 version of Windows
- 4GB of memory minimum
- Your understanding it is not supported at all
I've been running this for over a month. Prior to the hack I crashed ten times a day because I was always pushing Ninja so hard for backtesting and strategy development. After the hack I've crashed maybe once or twice in a month.
Directions: 0. Backup your ninjatrader.exe first.
1. Start menu -> Visual Studio group -> Visual Studio Command Prompt.
2. cd <NT install folder, ie c:\program files x86\ninjatrader 6.5> \bin
3. editbin /largeaddressaware NinjaTrader.exe
That's it. If you download a new version of NT you'll need to re-apply the hack. You can disable it by issuing editbin /largeaddressaware:no NinjaTrader.exe.
Also keep in mind NT7 will include this by default, plus so much more in terms of improved memory management. So don't even think about this hack unless you are experiencing constant crashes that you know to be directly related to OutOfMemory exceptions.
Here is a pre-hacked ninjatrader.exe file, this is 6.5.1000.10 only.
Again EXTREME CAUTION if you aren't an EXPERT don't even think about applying. I shouldn't need to tell you it's unsupported, and make a backup first. If it eats your computer I won't help.
