    Correlation Analysis

    What an utterly meaningless statement. This is like saying: I've studied global weather for 15 years... and can honestly say there is no place with 100% sunny days. So sun worshipers are screwed. Thankfully, there are no ultra-long term market correlations that any idiot with a NetBook...

    Forex "Pair Trading" or "Hedging"

    Short term USD/CAD and AUD/USD have vary high negative correlation... So scalping both concurrently gives you more options.

    Independent automating trading in Canada.

    It all comes down to what your average trade size is. The average trade size on the NYSE... Has come down from about 3,000 shares 10 years ago... to about 300 shares today. Flat rate brokers count on the fact that your trades will be fragmented... And you will pay a high cents/share...

    Independent automating trading in Canada.

    The Canadian model is based on NASD... But there is nothing "trivial" about being an NASD member... The entire system is geared to regulate retail brokers that deal with public Customers... So an independent trader becomes subject an onerous administrative load... And you will get a new...

    Democrats now officially pushing transaction tax according to Erin Burnet

    The US authorities can't even agree on a politically EASY short sale uptick rule. <Yawn? A tax on transactions puts Wall Street out of business... All trading moves to other countries... Lower Manhattan is taken over by 100,000 junkies again. It will never happen.

    Why does IB still use "Island"?

    Friday I had 188 trades shown as Island by SMART routing... 21% of my volume and virtually all ETF executions.

    1/4% Tax on all stock trades pushed in NY Times today

    That's exactly how online poker became illegal in USA. Even though the financial markets are 1000 times bigger... The Dems would do it in a heartbeat in the dead of night. Capitalism is hanging by a thread pending the 2010 election.

    Let's discuss academic research on mean-reverting trading strategies...

    Statement #1 is correct. Statement #2 is extremely misleading... Because cointegration will result in high correlation... Over any medium term period... For example, > 0.80 over 3 months. If correlation is lower than that... you will take too many losses to succeed. Statement #3 is...

    IB or fixed commission?

    Yes... Every execution is broken down in complete detail... In a section called "Unbundled Commission Details"... Except the Executing Exchange is left out... But you get that information in your TWS logs. Remember, the average NYSE trade today is about 300-350 shares. What IB tends to...

    Forex Is A Scam

    The Forex market is highly fragmented... And surprisingly volatile and inefficient. If you are an experienced stock trader with good feel... And you trade on a bona fide ECN like IDEALPRO... There is no reason you cannot be profitable. After > 1,000,000 stock trades... I've been...

    Forex Is A Scam

    You are misinformed and naive. > 90% of the funds out there are "skimming operations"... The Business Model is not to outperform anything... It's to stay in business and take 3% every year for eternity. If someone takes 3%/year for a lifetime... Say 3%/year for 40 years... They end up...

    IB or fixed commission?

    So you do 400,000 shares/month... You will definitely pay less unbundled, maybe $0.0045/share. But meaningful price reductions start at 300K shares/month... At 4000K with 50/50 add/take liquidity I pay about $0.003/share... So as you scale from 400K to 4000K/month... You would get a...

    Stat Arb: Pair Trading (US Equity)

    I do about 100 pairs... But have a lot of great analytical infrastructure... So 300 by 2 guys would be comparable. The bottlenecks are: (1) Finding opportunities by scanning a universe. (2) Making a decision to trade. (3) Entering an order. (4) Real time administration...

    Know how to program, don't know how to trade. Where do I begin?

    Sort the NYSE by daily volume... Look at the Bottom Third... And find a niche to specialize in. When you can make money manually... automate and scale up. The absolute last thing you wanna do... Is compete in latency wars with the Big Players... That means avoid anything very liquid...

    Fooled by Randomness

    This is pure fantasy... Just a bunch of AI jargon tossed out for effect... You must be < 20 yo. Do you go to a live doctor... Or do you have yourself diagnosed by an "expert system"? "Expert systems" of whatever AI approach you may suggest... Are too primitive to even reliably mimic...

    Fooled by Randomness

    The CAPM assumes that returns are Normally Distributed... An assumption which fails under extreme market conditions... Like when you get 3 or 4 or 5 Standard Deviation events. This is the heart of Taleb's thinking... Extreme events are more common than Normal Distribution would imply...
