Hello guys. I just bought a CL NYMEX MAR10 80.00 CALL at 0.23. Total cost according to IB order ticket was $232.75 however the order ticket also mentioned Initial margin as something $20k+. I am not buying on margin and since I am long call I am a bit confused why margin is even being mentioned. Can someone clarify this? My thinking is that total cost to me is $232.75 and no matter where the market moves, Ill only stand to lose a maximum of $232.75. Am I correct?
