You can test for stocks from more than 40 countries and US and Brazil are also included.
Stockalyze has built-in Trading System that uses RSI(14). If you want to use RSI(2) then you will have to create your own Trading System in Stockalyze which is very easy and you can do that without use of formula or learning to program. Have a look at help page here
to know how you can define your own Trading System. You can also watch demo video
and see how to do it.
In Lite Mode you can define your Trading Systems but will not be able to save it and so you cannot use it. But you can definitely get first hand experience about how to define your own Trading Systems.
Please give it a try and let me know how it goes.
