Right now it works by Taking a 5%fee from the ammount recieved. -> next it takes that number and divides it by the price of steem / price of tron.

so say you send 100 tron -> it says - 95 / (Steem/tron) that number changes by the second though so it's hard to give an exact ammount.

That being said the exact prices of the exchange change from second to second so the ammount recieved is going to vary a little bit (however this can work out in your benefit.

Esentially look at it like this -> quick simple way to make the exchange from tron back to steem. No need to worry about private keys, or verifying emails at exchanges and what not, just a quick way to get some liquid steem from tron thats just sitting idle.

I am using this exchange as a major learning tool, so while right now it is very minimalistic, It will serve as a way for me to learn various aspects of development.

I have the idea of a frontend in mind, however the more complex the process is, the more issues can arise from it.
