Hello @ll,
I am trying to implement a trading platform the allow change one currecny into another. The probelm is that I only found 3rd parties solutions with limited coverage in number of supported currencies. I need some suggestions.... How could I implement this service with largest coverage? Shall I use some free solution or implement all currencies support one by one and how? Is there any tutorial for imlementing exchange? I can code in many languages like php, sql, asp,, js, sql,etc...
Thank you

If you can build in any language as you claim, you could build it yourself without the need of a tutorial honestly and no there isn't any. If there are some, don't follow them because the open source projects could either have backdoors, security issues or simply outdated. I advice you to either stop this idea or hire someone with a lot of skills in coding and security to do it for you, you don't want to risk your customers funds (or yours too).
