Inverted pairs are “synthetic pairs” and inversions of naturally occurring trade pairs. For example, this page currently displays the ETH/OTN pair. This trading pair (with Ethereum as the base currency and Open Trading Network as the quote currency) does not exist on any exchanges listed by us. But the un-inverted version of this trading pair (i.e. OTN/ETH) does exist on one or more cryptocurrency exchanges. You may click here if you’d like to un-invert this pair.
