I like to know if this is correct in CEX.io... When Buy/Sell BTCs for US$/EUR$ and back...
Quote
To Buy&Save for the amount 0.05BTCs...
Under... "Trade: buy or sell BTC >> Buy BTC:"
Lower the (Current Market Price) “Price per BTC”, which in effect lowers the “Total: XX.XXUSD”...
The “Total: XX.XXUSD” SHOULD be lower than “Your USB Balance” total...
Example: (Currently) “Your USD Balance: 16.67” - “Total: 14.53USD” = 2.14USD Save/Profit.
