Very interesting post on our forum that I thought some may find interesting. Some users report that it does work and does help.

WARNING: THIS METHOD WAS NOT CONFIRMED BY OUR ENGINEERS. YOU MAY EXPERIENCE UNEXPECTED BEHAVIOR .

Post by Enalmada made here - MultiCharts: Trading Software for Automated Trading and Backtesting • View topic - Your MultiCharts will now use up to 3G of virtual memory

The actual post:
Despite having 6g of RAM I have had constant trouble in my portfolio backtester and multicharts running out of memory at around 1.8G. This post gave me the idea to solve the problem with LARGEADDRESSAWARE flag. I didn't have visual studio so I found an alternate solution. I hope this post helps others solve their memory problem until multicharts is compiled 64bit. (It would be awesome if multicharts came with LARGEADDRESSAWARE set by default until then...i dont think there is any downside to it)

I was able to set the flag quickly and easily with a free tool called masm32:

- If you are 32bit then set 3G switch as per these instructions ( I Got Pro Tools 7.3 to recognize 2.7GB of memory- Here's how - Avid Audio Forums) otherwise read on...
- Go to MASM32 Downloads
- Download from the link at the top
- Unzip and install it in a directory. Lets say C:\masm32
- Go to your multicharts directory C:\Program Files (x86)\TS Support\MultiCharts and copy multicharts.exe and MCPortfolio.exe to a backup location and also into C:\masm32\bin
- Open a command prompt and go to the masm32\bin folder
- Type this C:\masm32\bin\editbin /LARGEADDRESSAWARE multicharts.exe
- Type this C:\masm32\bin\editbin /LARGEADDRESSAWARE MCPortfolio.exe
- In your explorer window, move the Multicharts.exe and MCPortfolio.exe back into multicharts directory.

Your multicharts will now use up to 3G and I have not seen an out of memory error since.

See this post for full information of the instructions systems...

Same trick a couple years ago for NinjaTrader:

Ninja 6.5 largeaddressaware hack
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
- …

But with Ninja, I was constantly running out of memory. I don't recall ever hitting the limit with MultiCharts, I wonder how much tick data these guys are testing to hit the limit.
