Robert thx for clarifying. I actually looked at lightspeed before (maybe around 4 yrs ago) cause you guys had API accesss but was turned off cause of the high portfolio margin requirement. I think it had a net liq requirement of 500k vs. 100k at IB or 120 ish at tos. Is that still the case or can I have portfolio margin with less net liq nowadays.That must be a lot of volume.
To be clear, if you trade one side and let the option expire, exercise or assign, they charge you $1.10 plus reg and exchange fees. If you round trip the option, another $0.10/option plus reg and exchange fees. So if you trade one side and don't close the trade, these rates are a little high. If you RT the option, they charge your $1.20 which matches our listed rate of $0.60/option with no volume commitment. Then we give volume discounts.
