    IB changes margin rules abruptly without informing

    Wrong order gets through all the time through TWS and once it was identified, IB will reverse the order immediately. I have SPY shorts through several times in an IRA account, and it was immediately covered by TWS. njrookie

    are you in the 1%?

    I encourage folks to read the entire paper, instead of drawing a quick conclusion. The paper demonstrates if you pick the top 500 based on prior year's performance only, they also earn 0.3% per day the FOLLOWING year and outperform the hell out of the rest of the traders. If a fraction of...

    statistically speaking, randomness means you cannot predict what is going to happen next based on past information, including price/volume/fundementals etc. some traders really mean noise which will revert when talking about market being random. i would say at least 80-90% of time, market...

    gmst, compounding for short term trader is relative. once your account reaches 7-8 figures, it is going to be very very difficult without lengthening holding horizon. the even bigger problem is: how does one know he/she is in the elite group of top 1% trader? everyone on ET thinks he/she...

    vinc, If market is purely random, nobody can out-perform market consistently. So yes this is proof that market is not 100% efficient (an efficient market demonstrates random returns) and some traders can predict a certain component of market movement. No long term trader can beat the...

    the top 500 (out of 360,000) traders are probably taking lots of breakout trade. it is also interesting that the commission is about 1/3 of the gross return. it tells how careful one needs to be for risk management and how small the edge is. at almost 0.3% per day after costs, it is very good...

    Can I keep my Sharpe ratio higher then 4 for the rest of the year?

    if you export daily returns to an excel file, you can use SKEW and KURT function to calculate skewness and kurtosis. you can use average and stdev function to calculate mean and standard deviation as well. skewness measure the symmetry of return distribution while kurtosis measures the size...

    VXX a good buy at current levels?

    statarb should be generally defined. i define it as where you have statistical edge (say a good rsq). it does not have to come from pairs / spreads convergence. when vol is high and mkt become highly correlated (risk on/risk off mode), it is usually easier for directional short term...

    Trader P/L 2012

    losing 20K is not a big deal if you have a 1000K account. Always manage the risk first. Market can do anything it likes. One always needs to know what is the worst that can happen to one's account with the existing position. In my view, the last few weeks were nothing unusual. njrookie
