Interesting, mukhang legit 

Hello everyone,

We are building an Exchange Platform, just like Bitstamp but it will be serving local currency and bitcoins of coures. Built on Ruby on Rails and 2 main modules such as Trading and Accounting were built from scratch.

Is there any good open-source libraries for trading and accounting or anything that I can look at?

We are also planning to host this on AWS. Do you think AWS is secure for this kind of project?
