I think I have fulfilled all the requests from the forum

Except for my super fancy dancy button.

Is there a reason you don't show the service fees per exchange? Since you know the exact amount to trade you can calculate it and display it in the table. Also, the new fee column and Rate column should be sortable.
If value is odd or n/a or 0, then amount does not meet min/max requirements.
You should calculate that in the backend, and make everything consistent.
