When you log in for the first time to META1 exchange it is possible that the values between pairs are inverted. For example, in the following case we can see we are trading USDT/META 1, but according to the exchange the price is below zero

The reason why the price is below zero is because we are dividing the META1 token by USDT. In order to change that, we click on the inverted arrows on the top left corner of the exchange and click on the switch trading pair option icon.
