---reply:
by the last price I mean, the price of last happened trade (lastprice tab in a table there https://dexstats.info/)
by fiat price, I mean the last price converted to fiat value (USD price tab in a table there https://dexstats.info/)

without this information not possible to make a decision on trade without 3rd party sources usage and just these two numbers help a lot.

---reply:
The “differential” is an interesting idea, maybe we can similarly compare the prices to some external (?) market rate.

But how “the price of last happened trade”, which is essentially random, is going to help you “to make decisions on trade”?

---reply:
think it might be very worth to display (A/USD) : (B/USD) ratio as this number (so it'll be some kind of most liquid / recommended price)

With DEX format appearing many pairs which you'll never meet on CEX:

Let's say I have coin A and it's trading with good liquidity on CEXes in pairs to BTC/USD/ETH
But users want to sell coin A to coin B or ... Z and they will have a question - how to place good order or order on top of the orderbook fine to fill?

https://t.me/KomodoPlatform_Official/184259 - that's the situation I'm thinking/talking about.

To calculate prices you need 3rd party apps so user opening binance app to make a decision on a deal because it's showing both price per unit and total order depth and fiat price per unit
