Last several weeks I am getting a lot of questions about Metatrader high memory usage.A lot of traders use VPS for trading, signals, scripts. RAM memory is big problem.
What to do when MT4 is using a lot of memory? How I can reduce memory on VPS?
If you open 25 charts in MT4 and for example 500000 M30 records x 25 pairs into memory your MT4 terminal will spend 1GB memory in some moments.On other side events tabs, market watch window will spend memory too.
Try to restart VPS 4 or 2 times per month. I do that each weekend when forex market is closed.In that case whole VPS and Mt4 will refresh and work much better.
