Your second screenshot shows ANT at 0.0121 ETH, so your 700 is approx 8.47ETH. There's your profit.

However, there's no guarantee that's the rate you'll actually get on any particular exchange. If you want a direct ANT-ETH swap, you'll have to make do with whatever rate you can find available since it's not a massively popular pairing.

On the other hand if you want a better reflection of the full value change, you can switch to BTC as an intermediate currency first, but you'll end up paying more in fees/charges.
