I am not sure if the fee is depent on the actual license price, since we still are in the XMAS sale.
An additional exchange costs half the price of a regular single license. Currently it's 0.025 BTC.
Until end of 2017, there is an XMS pack, that includes all 6 exchanges and the Tradingview add-on.
You can find the actual offers on
www.tradingbot.org at the XMAS category.

Thanks. With the Christmas pack can I work on multiple exchanges at one time? Or do I have to choose what the active Exchange is? If I bought from you do you offer any configuration and assistance getting things running?
