If by "forex website" you mean for offering your own services to clients, then you're looking for a White Label solution.
Since you 're also looking for self-hosting and access to source code, then the best option I know of is the M4 Platform which provides all source code for a one-time fee.
There are many closed-source White Label solutions out there depending on your specific requirements.
