Real trading, is it possible to add and subtract currency pair/pairs aside the ones displaying as the quote when one downloads mt4?

I’m seriously testing everything I have been reading at the school of pipsology and on this great forum.
Here’s the thing, I realized that MT4 malfunction or is altered, my indicators misleads me and are never in agreement whenver I adds or subtracts currency pairs from the initial pairs displaying as the quote as at time the MT4 was downloaded from my broker’s platform. I
Wouldn’t want to go commit blunder when I go live. Is it really possible/advicable to add or subtract currency pairs or one should just sticks to the ones given/displaying at the dashboard at any point in time by the MT4?

Technical indicators on your charts are not dependent on the number of currency pairs you have, add or subtract to the market watch window on the MT4 platform.

To answer you question, yes it is possible to add or subtract curency pairs on MT4.

You gave me the impression from your post that you worked out how to do that already though.

already found the part that error?

Ok thanks, but I stand to be corrected. It’s not possible to add/subtract currency pair/pairs in demo trading because it alter the functioning of the MT4.
While in live trading, it’s possible.
