Memory usage warning

My computer's memory is 64g. The memory option in the sqx configuration is set according to the picture. I empty all the databanks, and then load strategies. Sqx will prompt "memory usage warning". I check the task manager. At that time, the memory usage was only 30g and the CPU usage was only 10%. I don't know why.

You can increase the max memory size on Configuration -> Memory tab as it is on the printscreen


StrategyQuant is java based application and with this option you set max JVM heap size. It is displayed in "Heap memory chart" on Engine panel.

The maximum usage shown on the heap memory chart is less than 30g, but I set the set maximum memory to 60 in configuration——memory Options tab.

Please open file StrategyQuantX_nocheck.config and check if there is a line with memory option 60 GB ......option -Xmx60g


Did you reset SQX to apply the setting ? Is it a fresh install or updated version ?

By any chance do you have 2x 32gb memory sticks? Is it possible SQX is only recognizing one of them? I ask because SQX was having issues recognizing 2 CPUs on a dual socket CPU computer and I can't tell if this is related.

1.My memory is really 2 * 32g. Does sqx not support 2 * 32g of memory?

2.Now there is a strange phenomenon in memory. All the databanks of sqx are empty, but sqx takes up 43g of memory.

My SQX is a fresh install.

After modifying the configuration - memory option, I restart sqx.

which version of SQ are you running exactly? I tried it with the latest 131 Dev 3 and setting memory works correctly there, I can set it to 60 GB and it is respected in SQ.


It shouldn't matter at all that you have 2 memory sticks, I have 4 on the test computer.

@Jordan, check the bottom of the page, theres a section for the development version of 131 if you want to test it out with the newest code to see if it works.
