yes that's right. if taxes are an issue, zimbabwe or may be the republic of congo might appear attractive. but then it turns out there might be some benefits to having a stronger government afterall.

Anyone trading TSE stocks through interactive brokers from the US? I'm wondering how bad the latency is. Thanks.

here's the nasdaq requirements https://www.sec.gov/pdf/nasd1/4000ser.pdf

say you have 10 methods. let's make it easy and say each of them works 50% of the time and fails the other 50% of the time. you don't know when each of them work, and when each of them fail, just overall they work 50% of the time. how would you make money in the long run?

better lucky than smart

So how did it work out for you after quitting? Do you now live large in Miami with mansions, art, and boats?

I don't know, my experience with MM / microstructure is that markets can trend during the day which means you could have a whole day where the price has momentum pretty much in one direction -- and whatever price action rules you came up with will very likely bias your trades in one direction...

Okay so with the TF you were you earning 1 tick spread on average per round-trip trade? How long were you holding a typical trade? How did you close your positions -- with opposite limit order quotes? If so, how did you ensure it would close quickly enough? How did you ensure 50/50 long short if...

what was your commission costs per day? what is your commission per trade or per share? what was the commission minimum on a trade? if you claim to be doing HFT, what was your network latency? what type of hardware and network connection were you using? were you colocated near an exchange...

Your PL curve proves that you did overfit -- if you think that a year of profits is "proof" that your system did what you intended to do, then you probably haven't studied random walks enough. By the way, you said earlier you used hundreds of variables to fit the short term price action. Then...

Curve-fit means you have too many parameters in your model such that it fits perfectly the data you trained on (past data) but has very little ability to generalize to future data. So you will have a perfect back test but it will perform absolutely horribly during live trading. This is not a...

if that is the case, why is everything made in china nowadays??? if automation is so widespread, why aren't more things made in the USA by robots??? still think labor cost arb is more profitable than automation.

good point. labor cost arbitrage is probably one of the reasons for sustained corporate profits in the last 20 years.

Yeah, I know exactly how that game is paid. "My base salary is only $150K", key word "base".

LOL, look at the fine they want from him: $130K. that's probably about his bar tab on a good night.

just fyi, here's a breakdown of who are the 47% http://www.dailyfinance.com/2012/09/19/mitt-romney-surprising-facts-pay-no-income-tax/

] okay two things that are believable: profitability didn't last (of course, it's curve-fit), and he couldn't sell the algo. other than that, the rest of the story is still fishy.

This whole article appears a little fishy. He curve fits the hell out of 10 second price action, and he talks about how much time he spent making a perfect simulator. Then no mention about transition to live trading and says he made 500K with almost no drawdown, but profitability only lasted a...

You know that's what they were saying about FEMA until the hurricane literally hit people's back yards. Then suddenly, it's thank God for FEMA.. Perhaps there are reasons for having embassies, the CIA, the NSA. Perhaps a good reason we haven't had a terrorist strike recently might just be due to...
