RedLotus28 : You can try Papertrade first before considering real trading.

10baggerbamm : so the first thing if you don't understand options is read everything you can there's plenty of online videos for understanding option basics understanding the terminologies understanding your risk is it limited is it unlimited you need to understand about time value and decay and volatility premium. I would also caution you that buying a put or buying a call statistically 90% of the time you will lose regardless of how confident you are.
using your example not factoring in fees and assuming that you're buying on the ask and selling on the bid.
one contract would be at the close prices I'm using would be 13 per contract so $1,300 for December 20th expiration of 440 strike .
if on expiration day let's say 359 and 50 seconds with a market closing at 4:00 p.m. if your Tesla is any less than $453 on the common stock you will lose principle. so your break even is 453 because it would be a strike Price Plus your premium that you pay.
the $13 price of your initial purchase is based off of the time value so the greater the time that you go out the more you pay for an option contract that's number one and number two you have a volatility premium the more a stock goes up the quicker it goes up the more volatility premium that you will be paying in also inversely the faster that option contract will decay as it approaches expiration.
I hope that's clear for you I'm not 100% awake right now it's only 2:47 in the morning East Coast time
if you have any other questions ask
