Hey 1) what is the price average of 1 spy contract ATM one month out on average ? 2) what happens if i have A SPY AT 278 and i sell one at 278.5 what are my risks ?
you better start reading a few good books on options ... there is just no start at answering your questions ...
Pushing a wheelbarrow full of steaks and pork chops through the lions exhibit at the zoo doesn't make you a zookeeper -- -- it makes you a meal.
Here's a pretty readable book on options. It's probably a good idea to read it from cover to cover and then return to the forum to ask more questions.
