Hi jackt,
That’s correct – the system will download pairs simultaneously, however it will only make one request at a time per-pair. If you are concerned about requesting too much data I would suggest manually downloading one pair at a time. The main intention of the multiple-pair feature is so you can easily generate MT4 or CSV exports for all your desired pairs in one go.
Also, remember that the data is cached on your local disk so once it is downloaded it will no longer request the data from the remote servers.
Hope this helps.
