Hello, dev.
Please modify the internal exchange. See how the best exchanges are made. In our exchange nothing fits on the screen, it is necessary to scroll many times to move from the purchase menu to placed orders, and then copy the price and the number of coins. In the internal exchange, the workspace is not efficiently distributed. The exchange is not functional and not convenient. It is very irritating. Money and irritation are not compatible.

Remove all exchange limits.

And why do you need to separate usual and trade balances at all?
