What is Contra?
The world is full of fraudulent FX information products.
If you are not careful, you may often be swept away without thinking for yourself.
That is why it is important to have the ability to think for yourself and verify with your own hands.
I hope that as many people as possible will use this application as a tool to resist such a trend in the world.
With this wish in mind, we have named the app Contra (against the tide).

Contra is a service that will continue to grow with you.
We are committed to improving our service and to make it available to as many people as possible.
We are looking forward to receiving your feedback on the features you would like to see improved or added, as well as your highly positive reviews.
