first off,

DON'T trade options if you do not fully understand them.
They are a powerfull instrument ( derivative )!
You could do some homework on https://academy.investopedia.com/products/options-for-beginners
and when that fully understood https://academy.investopedia.com/products/advanced-options-trading.

There is no free (easy) money in the market.
Thinking so, not comming fully prepared, will set you up for large losses.
