Kindly check your pm. I send you a link to a telegram group full of people who does options.

Like I said just so many times. Just apply for margin. You don't need to use it. As long as your cash is positive, you will never be charged any interest for it for IBKR.

That's the difference between the initial option $8.50 (Buy to close) and the new Option $9.00 (Sell to open). 

Nope, it took me two months to recover $400 that i lost on my 1st option trading.    but i only have a capital of $4k so it's more on trial and error... Don't even think about earning $100 per week, it maybe possible with higher capital, but as of now. I'm aiming $10/contract/week now. Just to be on safer side before a market crashed. I'm playing wheels, just selling Puts then selling calls and repeat. Have not try buying a Put/Call (other than buy to close)
