Bonjour,
Market makers like rebates and need ‘uninformed’ traders.
You can encourage uninformed traders by setting the trading fee to 0% - see my post on loss leader markets. https://dydx.forum/t/loss-leader-markets/2361/9
Rebates are easily achievable by a parameter change to make them permanent.
You can’t have both at the same time, of course, but I’d say that uninformed traders are more important to a market maker (having been one myself).
Cordialement, Tresgard
