Huge Ram usage on MT5

 

Hello,

Anyone can help me please, i watch 28 pairs everyday and i do some intraday checks on all of them, i use only one chart and then use a symbol changer to faster switch the pair to analyse. I noticed that the ram usage is always increasing, getting to 7GB ram today. It is normal ? why the MT5 always increment ram usage when i switch the chart ?

Thanks in advance.
