Does everyone here use a margin account? I do not at the moment as it goes with my risk adverse thing, figured why not just gamble my own money. I get the concept and all, just wasn't sure what most do. Can you choose to use it on some trades and not others, etc?
Also, I know they charge interest by how exactly does it work? For example if I covered 10 puts instead of 1, am I charged interested from the day the sell is filled? It is annualized?
Example: Option X has strike price of 5$(ignore premium for now), I normally could only afford 1 put as my account is then locked of 500$ balance. But if I use a margin and say but 5 puts(2500$), would that be 2500$ borrowed or 2000$ or can I choose? Let's say the margin rate is 6%, how much interest would I actually owe on the 2000$ as I would obviously need to factor that in to any type of profit calculation....

Gives an example but it is a little confusing to me. It mentions a 100,000$ debit balance(how much equity/cash I have on hand) would be 6.825% or 18.96 a day, but do I pay that every day no matter what or only if I am using all 100k?
