Welcome to

Welcome, Guest!

This forum was established to help traders (especially futures traders) by openly sharing indicators, strategies, methods, trading journals and discussing the psychology of trading.

We are fundamentally different than most other trading forums:
  • We work extremely hard to keep things positive on our forums.
  • We do not tolerate rude behavior, trolling, or vendor advertising in posts.
  • We firmly believe in openness and encourage sharing. The holy grail is within you, it is not something tangible you can download.
  • We expect our members to participate and become a part of the community. Help yourself by helping others.

You'll need to register in order to view the content of the threads and start contributing to our community. It's free and simple, and we will never resell your private information.

Your MultiCharts will now use up to 3G of virtual memory

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


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:

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.


Due to time constraints, please do not PM me if your question can be resolved or answered on the forum.

Need help?
1) Stop changing things. No new indicators, charts, or methods. Be consistent with what is in front of you first.
2) Start a journal and post to it daily with the trades you made to show your strengths and weaknesses.
3) Set goals for yourself to reach daily. Make them about how you trade, not how much money you make.
4) Accept responsibility for your actions. Stop looking elsewhere to explain away poor performance.
5) Where to start as a trader? Watch this webinar and read this thread for hundreds of questions and answers.
