uhm.... this thread actually has very little to do with options. it seems more like a thread about "hey! what stock do you think will go up?" or "hey! what stock do you think will go down?" guy, i hope you're clever enough to not take stock tips from the internet. :p

your other option is to get data for historical implied volatility and then use your model to find the prices. of course, they won't be totally precise, but most should be around the ballpark for general theoretical testing.

sorry, i was trying to buy some shares. didn't mean to move the markets that much. i'll do smaller size in sequential orders next time.

well, they have all the basics, but the features just aren't that advanced at all. it depends if you're only interested in expiration value or risk premium value calculations. they don't reflect the entire risk portfolio with much flexibility for the latter. it also won't let you fudge around...

i had a '94 second-hand nsx, and it broke down pretty often. timing belt always needed to be replaced. transmission had to be fixed a few times. the tires always wore out easily. the shifter sometimes wiggled at high speeds to remind you that it's only a japanese car. you'll be writing a lot of...

that tradestation toy is crap and not very powerful. actually, there aren't any existing commerical option trading products that are powerful. it depends on what you're doing, but if you're interested in anything beyond the most basic stuff, you have to write your own.

paying taxes and whole lot of it is good. most of the time, it means you're making money.

he pretty much outlined and explained everything in the q & a. he's a premo collector. probably short spx strangles.

if we were playing poker, i would go "all in" on that statement and take all your chips.

nope, not pushing any carts at the supermarket, but i do drive a jaguar. thanks for asking. not bitter at anything at all. why would i be? and what's up with personal attacks? you have a lot of irrational hatred for strangers in you... so how are you doing? (you don't have to answer...

i'd rather be a fugitive hiding in south east asia or something than spend the rest of my life rotting in prison.

don't take the prop job. that's your last last last resort when you got nothing else when even burger king isn't hiring. take the options marketmaker trainee job. be exposed to options volatility and master concepts of hedging, repairing positions, and options risk management. those are good...

he should had fled the country.

the word 'edge" has been so poorly overused by guys with no edge that it really has lost its meaning. it's become more of an empty buzzword these days. so next time you hear the word, just ignore it. :)

wow, so much animosity in this thread. they should rename "elite traders" to "madly depressed traders."

just because they're deciding to go to pennies, it doesn't mean their markets will be penny-wide. i doubt even a drunk marketmaker would offer a market like 0.79-0.80. they're probably just trying to beat NBBO for some of the 'dime or greater' spreads. if something is 2.05-2.15, they'll...

delta neutral is always recommended to avoid overnight gap risk when you think there's going to be an explosive gap move (foreign elections, currency instability, etc.) but are not sure which direction it is headed. you should use it as a risk-reducing function for these events because that's...

coach, your approach is that you are looking at everything at expiration. but there is no rule that you have to hold every position till expiration. values change wrt to time (and other things), and you can capitalize anytime when those values change. so look at option values from...

mte, first of all, no one is encouraging anyone to trade where he will experience 20-25% daily swings. kai is carrying excessive deltas for an account of his size. and as for this topic, i know you're looking at risk at the extreme level, when time goes to zero or vol goes to zero. but...
