In straightforward words, yes, you can have any number of brokers/accounts you want to link with a single Forex VPS. However, it does bring potential issues, and that's related to the shortage of the resources of VPS to support multiple MT4 instances.
No worries, there's a solution to that as well.
You just need to upgrade RAM and/or CPU resources, and everything will run smoothly for you.
If you are from Denver, USA, then we do provide you the options of expanding the RAM and/or CPU resources. For customers from all other locations, we provide easy upgrades from your existing Forex VPS hosting, and all plans are very reasonably priced. Tap HERE to contact us.
