NT7 performance with strategies running

[nicknamed]

Hi,
I want to test my strategy on as many assets as possible, it does not make many trades so the test should not slow down as with other strategies that generate 5000+ trades on 10M timeframe. I just do not understand one thing. When I open 18 windows (consisting 8 currencies and 2 futures - with all 5 currently available (even partly) contract months to do trades), then NT7 stops working even with RAM usage between 100-250 MB, but I have 12 windows open (8 currencies and TF contract on 4 windows) with 450 MB RAM usage and the test is running fine. While I tried more windows and I got to 500-700 RAM usage and the test sometimes run to January before NT7 hanged while another time it run only two weeks and did not even reached August 2009. So the moment when NT hangs cannot be repeated as it is always some other time. It does not seem that it is related to RAM usage issues. There is only certain visible correlation with the number of opened futures-contract-months windows. Please do you have any suggestions how can I test it on say 30 assets as quickly as possible? Is there any possibility to test the strategy on Market Replay Data without opening Workspace/Charts (as just opening workspace eats plenty of RAM)? May it be influenced by the amount of data in data directory where I have 26,5 GB of ntm and nt2 files?
Any suggestions welcomed.

btw. why when I run NT7 beta 18 it eats sometimes 50 MB just after start and sometimes 355 MB of RAM? Just plain NT7 without anything. That is something I really do not understand.

I am using 64bit NT7 beta 18 on Windows 7 Ultimate 64 bit

Hello Nicknamed,

For running strategies live:
You can run from the control center rather than a chart.

For Backtesting, you can use the Strategy Analyzer and run a report on multiple instruments at once or individually.

beta13

Hi,
well I did not mention that I had no such problems mentioned below with beta13. In other words, my scripts are working fine in version 13 and few versions under 13 (I did not test it in all as I do not have them), not working in 16 and 18, I did not test in beta 14,15,17. I would like to move to higher version but it is more buggy than lower versions in my opinion.
Thanx for the tip of control center, it did not help with performance/freezing/hanging but I can save plenty of time running strategies.
