When I was first learning, my commissions were approximately equal to my profits before commission. I've shaved those down to a tiny fraction of what they once were, so as I've scaled, they've dropped to almost insignificant. This amounted to a 18-19% tailwind just by cutting my commissions. I pay more on bad fills and mistakes (firing a limit order on the ask, to buy, when I mean to hit the bid, for example) than I do in commissions.I was wondering for those that trade 4 legged spreads on equity options, what percentage of your P&L is going to commissions. For me its about 20%, thanks
Especially when you're 12.50 + 0.15, that wouldn't make sense unless you were big volume. 24 contracts is where I would break-even on that vs. IB, and if you use not tier pricing--if you were trading that much volume and taking fills on non-marketable orders, I doubt you could get to that 12.50+0.15 with IB. Overall I pay very little in commissions, and the majority of my commissions come from marketable orders when I'm taking profits on ITM contracts. When I'm opening or stopping on OTM contracts, I'm something like 0.25 per contract (tough to be precise because I haven't crunched the numbers this way because the commissions are so insignificant now overall).
It's easier for me to count commissions as a percentage of my account than my P&L though. Sitting around 1.6% annualized right now (in a very active account).
