Wow, you made $11.33 in 20 days, that's terrific!

Watch out everybody, a market maker star is born!

It would appear that the majority of your trades were positive, so that is commendable.
However, if you charge your clients 30% of the profits + a $10 VPN fee, while conducting the same trades for them via API, that means they are sitting on a net loss of $2.40. Maybe you can squeak out a few more trades before the end of the month to put them back at a net zero.
