Lol, ok... you are entitled to your opinion.

Just go to the dictionary... most definitions will start with something like "intentional perversion of truth in order to ___". Unfortunately, in the subjective theory of value, there is no "true" price. So, if you think there is a "fraud" in your mind... then just don't bother participating...

I guess we'll have to agree to disagree earth. It's you who doesn't understand that if two parties both agree to a trade willingly... then there is no fraud. Before that, whatever the bid/ask, it's just a negotiation.

I've seen this confusion a million times. IMHO it's caused by subscribing to the labor theory of value instead of the (better suited) subjective theory of value.

Presumably because that's where people think there's a bigger information asymmetry and more profit to be made by fishing in the middle. But, as seems to be the point of the entire thread, there are just some "dumb default" bid/asks which can be made to rest in the order-book for the sake of...

I know earth... but I'm pointing out that there's a contradiction in your thinking overall. If there's nothing wrong with what you suggest, why would there be anything "illegal" about the bid/ask spread? That said, I think it may just be that English isn't your native language. Perhaps the...

Lol... starts thread named "illegal option orders in the orderbook", asked about quote stuffing and replies "There is nothing unethical in this".

We're clearly doing things much differently.

You mean quote stuffing... not a great long-term practice. I think you'll eventually get nailed for doing that kind of thing. Hard to pull off at a retail level too. Not to mention, if you're not extremely careful, you might cross with someone who knows more than you. Better to just do an honest...

And what you do suggest as an alternative? I actually hesitate to use anything too avant-garde since I'm a pretty risk-averse sort of person. Plus, at the end of the day it is just a guess... basically. Ok, maybe a well-informed guess, but still. Not to mention, the data providers are doing...

Lol. I was just using a 90 day EWMA (a=0.94) like everyone else apparently, but switched to garch a while back... tough for me to say if it made a huge difference. I don't trade anything too close or too far from expiration though.

I don't trust closed-source software. Those pricing engines are all over the web, they could have been written by a cock-eyed half-wit, they're too slow to actually implement in a trading system. Sometimes I'll play with them for fun or just to double check something. They're good for messing...

Well get to it earth! Determine what you think the "correct" price is, calculate your IV and start printing some extra pocket change. Personally, I prefer to do it the other way around... I make an estimate of what the vol will be and then look at the price. I figure it's easier and since it's...

That's probably because people on the buy-side will be more interested in the ask and people on the sell-side will be more interested in the bid. I think it's important to remember that IV is, in a sense, a make believe number... it's trying to quantify expectations; of which there may be quite...

Yeah, but Des, ever since you've changed your privacy settings... your messages don't show up in your followers' news feeds. IDK if you (or many of the followers) are aware of that, but it's a bummer nonetheless and makes following somewhat pointless.

I used the roster of the '27 Yankees to predict the outcome of today's game and it worked great.

Of course there's a human behind the curtain trying to game you. Trust no one, ever!

I thought the latest versions of Microsoft operating systems (since 10.x or so) basically were spyware/adware themselves. Is that even a question anymore? https://news.ycombinator.com/item?id=13438446 https://news.ycombinator.com/item?id=35787707 https://news.ycombinator.com/item?id=34712640...

And yet he comes back for more!

:-) True! Nonetheless... I prefer a full roster so every little bit helps IMHO.
