Is there anyway to modify the "terminal" desktop MT4 version to make the winning trades show in blue and the loser ones show in red like it appears in the mobile version.
as in the attached image they only show in (-/+)
I will be very grateful for any help
You could build your own (on a chart) to emulate that.
You'll need to research that - it definitely isn't a "couple of minutes" job that I can explain in a forum post, particularly if you don't have very much knowledge of MQL.
There are some useful links in here:
