#Refreshing All Charts - Open

I try to test with simple indicator that I know for sure all charts refreshing while I try to switch Pairs, so when I try to switch one chart then all of other charts starts refreshing, but I do not want to all charts starts to refreshing cause few of them for Trading Strategy.

Q:  How can I prevent that all chart refreshes while I switch Pairs for just one chart, please?

Thanks in advance.

( I hope I will get good answer till Monday )
