Is commission charged?
Yes, per side, so a round turn pays twice. It leaves the balance, so both floors and the profit target count it.
Every fill is charged at the rate Lucid publishes. A micro is fifty cents a side, micro gold eighty, and micro silver a dollar sixty.
It comes out of the balance, so it reaches your equity, so it reaches both floors and the target. A round turn at the full micro cap on a 50K spends forty dollars of a twelve hundred dollar daily limit before the trade is right or wrong about anything.
The rate is stamped onto each fill as it prints, so a change to the schedule can never reprice a trade you have already taken.
Exchange, clearing and NFA fees sit on top of this at Lucid. Those are not charged here, so the number you see is the floor of what it would cost you and never the ceiling.
