New coins and pairs
Most of the time, the software is able to detect new coins and new trading pairs. If it does, HTS will add this new pair into the trading pairs list automatically.
You just need to reset the software and it should be available in the drop down menu of your trade bots.
Trading pairs that do not have any trading volume left, will be blocked automatically. This avoids you placing orders that can never be filled. (It is not common to see this happen.)
