yes

Thank you!!

be careful not to day trade too often if you have less than $25000 in the account in the US.

Probably not going to be the smartest thing to do. Pretty good way to get smoked quickly as well. It'll be hard to make enough after fees with the way most of the brokerages work and you're giving up absurd edge to get the trades done if you are retail.

Yes, if implied volatility rises more than the time decay you lose that day. Also if you move towards the money your option will become more valuable through its delta.

It would probably have to be a fairly significant move on either of the above two though in order to cover your transaction costs (commissions and bid/ask spread)

"Yes, if implied volatility rises more than the time decay you lose that day"

Wouldn't it be the contrary?

BTW not only implied volatility influences the price, but of course the stock price does to. If the stock rises, the option will also rise.

duh

Braz, it's not the contrary and that second part is wrong for puts.

Brazil: You're fucking retarded.

what a bullshit rule... I found options that move significantly...

lawl you're fucking retarded dude. Just hand me your money--at least I won't charge you transaction fees or require you to post margin or even create and account for that matter.

already up 322%

^^^^ I call troll.

just open an account and short shit

^^ yeah I was looking into the whole shorting penny stocks deal but the collateral requirements are insane.

If the implied volatility rises that means the price of the option will rise. Vega tells you how much the option price will change given a 1% change in volatility.

Intraday option trading is extremely difficult but that doesnt mean there are not opportunities to make money on explosive moves particularly if you are anticipating a high volatility event that the market has not fully priced in.
