If you plan to use one MoonBot terminal for different exchanges, you can register keys from another exchange in the same bot and switch between exchanges using the exchange selection drop-down list. However, we recommend making copies of the MoonBot terminal, and in each of them register API keys only for the selected exchange (MoonBot1=Binance, MoonBot2=Huobi, MoonBot3=Bittrex). PRO version owners can make an unlimited number of API keys from the same account of one exchange with PRO support for free. This requires: 1) Copy the PRO version of the MoonBot terminal into a separate folder . 2) Run the MoonBot terminal from this folder. 3) Make sure you have a working PRO version of the MoonBot and the top left hand corner of the Settings - Login tab shows a green MoonBot ID. 4) On the tab Settings - Login click "Register another keys", enter new API keys instead of the current ones and click "Register API keys". Be careful not to leave any characters from the previous keys in the fields and when copying the new ones, do not trap a space at the end. 5) After this MoonBot with the new keys will also become PRO. The MoonBot terminal can be stored on a flash drive and run from other PCs. The FREE version of the MoonBot terminal can only be run in 1 instance.
