1c is nothing for the $40 stock, but 1c is A LOT for $1 option (1% for one way and 2% for two way). This is not include your commission, let say $2, and your total cost is 6% per trade regardless you win or loss. Don't try to argue your edge will be more than 6% as it is rare and not for retail traders that looking only at tea leaf(chart, indicator, MA, CNBC and etc). A roulette in casino will only need the 2.7% "commission" and they never loss in long term.
Note:
My commission with TOS is only $1.00 due to the size of my account

. I know IB will be cheaper but I need a more reliable platform because I only trade SPX and RUT in volume (slightly OTM with about 2 months out) and i need a good filled.
** I never trade SPY options - READ this reply again for 5 times and you know what I mean**
I will no longer respond to this thread. All the best to JC.
