Custom flat files are 10 to 100 times faster than databases... And can be serialized in RAM for even greater speed. You need an very high level of complexity in your data analysis... To justify using SQL databases.... Which probably means you are overfitting. Keep it simple... it's all...

Not very useful... Unless you opine which methodologies are more correct... And which vendor is pushing out sub-optimal numbers.

You would give fellow prisoners the chance to gamble on financial markets... In exchange for packs or cartons of cigarettes... Which you would then exchange for sexual favors and/or drugs.

If this is the case... The tournament is very poorly designed... And rewards a random luckbox.

No, it's not that simple.

5-10 years is VARIED market environment... Would be a reasonable sample to judge a money manager... Even then you have to drill down... And understand the strategies employed IN DETAIL. Simply allocating capital based on short-term leaderboards... Is a highly suspect statistical...

You can enter the initial order manually... But it has to be Automated to scalp once it's hit... So overall perhaps 50-70% of orders will have no human intervention... Which leverages a Pro Trader's time by a factor of 3. I would consider that the minimum for Automation. In terms of...

With a lot of these gray area things... You have to be persistent. My home TD Canada Trust branch manager... Became obsessed with some Ontario business license. So I went to another branch... And if they had any questions... I refered them to my lawyer... So opening a US Corporation...

I only have one Canadian bank account for the Delaware LLC. Of course a Delaware LLC has to file with the IRS... But a single-owner one is viewed as a "disregarded entity"... And has very limited filing requirements... Especially if your country (Canada) has a good Tax Treaty. I'm still...

Withholding is not a function of structure... It depends on the Tax Treaty rate and minimum is 15%. I reside in Canada and did this with IB: Form a US Corporation like a Delaware LLC... Which might cost $2,000... And call an institutional salesman at IB USA in Greenwich, CT... Then...

You don't have "failsafes". You are entirely dependent on a retail broker server... Where no one gives a shit about 3 or 30 seconds or whatever... Because the average reporting time is, like, 1000 ms... Plus you're entirely exposed to being swept in a fast market... Because you are not...

I'm not sure why anyone would leverage Preferreds at 4:1 at a 5 year high... Sure you might be yielding 25% for a while... But such a strategy is way too simplistic to work in the long run. Way, way way back in August 2011 PGF dropped 15% in 3 days... Which would have forced you to...

This sounds like a non-trader's idea of trading. One word: over-fitting

You won't build a better spreader than CQG or TT... People with 9 figures in capital have been doing this for years... And you have chosen to go HTH with these people. In poker it's called poor table selection... Like sitting in at the Big Game at the Bellagio with 10 BB. You have to be...

The best philosophy is to view oneself as disposable... And carry cyanide capsules in case anything goes wrong.

You can use various... as long as you can interpret it in real-time. The point is to avoid having orders cancelled by IB. IB is highly intelligent in this regard. Since I trade well hedged, lo vol stocks... I often have 200-300 orders worth > $1,000,000... With < $30,000 in Buying...

You can always take a screen shot.

This is why you don't get conned out of $500/year. http://theothermccain.com/2012/11/12/when-youre-down-to-your-last-4-million-hallucinogens-may-seem-fun/

This. The whole idea of large alpha in 2012 = "tenuous". There has been a major Cultural Shift... People get that retail trading = casino. 100% of my profits come from capturing $0.03-$0.04 spreads... Whereas in the 90s there was lots of alpha. Probably 90% of IB's profits come...

You are over-complicating a very simple concept... This is a not a good sign. Whether a game has a "social function" or not... Has no mathematical relevance from the perspective of the competitor. Successful traders have a near-instant understanding... Of the basic gambling concepts...
