Invested: 0.1600 DAI
Fees: 0.0036 DAI
Earnings: 0.2340 DAI (net earnings 0.1310 DAI)

Should net not be 0.2340 - 0.1600 - 0.0036 = 0.0704?

[Adamantios]

balance == 0 won't match the trader's behaviour in case the remaining balance is dust.

[jmoreira-valory]

if balance > 0 --> It has not been redeemed (regardless it's dust or not)
if balance == 0 --> It has been redeemed

[jmoreira-valory]

Invested: 0.1600 DAI
Fees: 0.0036 DAI
Earnings: 0.2340 DAI (net earnings 0.1310 DAI)

Should net not be 0.2340 - 0.1600 - 0.0036 = 0.0704?

@DavidMinarsch Yes, I just inserted an additional transaction manually as an example and didn't edit the numbers correctly.
