Short answer
Your fee drops automatically based on your trading volume over the last 30 days: 0.45% under $100k, 0.35% from $100k and 0.25% from $1M.
The window rolls, so your rate is recalculated as you trade and as older trades drop out of the 30 days. There's nothing to sign up for. You can see your current rate in Settings.
If you joined through a friend's link, your 10% referral discount applies on top of whichever rate you're on.
