Re: amazingIndustry Ah come on. Today - - FX spreads have narrowed. - You'll get arb'd by a machine if you price wrong. - There's no room left for manual screen quoting. Do this at your peril. Otherwise nothing to see here.

Agreed. But I'd also say that while paying retail commissions, trading faster than manual doesn't necessarily help.

Fastest selling, most highly leveraged retail product, with super-light regulation .. now has retail punters wondering why they're not uber-rich just yet. Oh, it's because of central banks. Ok..

Does calcing in a spreadsheet count as manual?

Similar story within brokerages, with less risk.

This is middle office mumbo jumbo & buy side voodoo. Not trading strategy development. Risk managers use these models to police the front office. Risk to Trader: "You need to unwind that, because the model says your risk is too concentrated". The middle office is another career path for...

Dude, you’re starting to sound less smart.

The skew and kurtosis moves over time.

I agree with this part. While there is a small subset of traders from a quant background, these guys are the exception rather then the rule, as far as I have seen. There are still desks full of knuckle dragging sales traders, execution guys, and prop desks that run off economic, sector...

atticus - Natural vs Iron flies? Other than order entry .. which, when and why? :( I've tend to think in terms of iron .. mainly because I "like" verticals. Edit - Not an options guy. Just thinking outside of comfort zone here.

[/B] I meant the filtering aspects, feature extraction etc. The hard bits. Anything post-trade is a dead end. Intellectual wasteland and career limiting quagmire. (Or a good job in Bangalore).

I have built one. PM me and I'll send account details back. .. Seriously though, it's not impossible to do for a price/time priority market. Difficult, but not impossible.

The "medical imaging" bit is interesting. That makes sense.

Exercise a call to sell shares? Wow. :confused:

The article leaves out anything about the actual naked short selling. Implies that writing options is "bad / illegal" :confused: Buy stock, sell options, go to prison?

+1 Target market here is the lazy & intellectually challenged. Ideal customer being a not-so-bright, but cashed up widow or orphan - windfall wealth that is unrelated to the skill of the individual. "I'm really not a math person, but I recon I'd be a great trader if I could just find the...

No bites?

I recon I could do it.. so long as overlaying a synthetic vega offset by sizing cash stops at the right price steps .. still counts as a straddle. Maybe. :cool: edit - Do margin calls count as a vega offset?

If your DMA is slow, and you're only managing a small set of names, manual can be good enough.
