    Hedge Industry - Bye Bye?

    Lots of funds will close down simply because it's in the managers best personal interest to do so. Most funds have a "high water mark" clause, so it's going to be a long time before some of them will be compensated highly again. So better to close out (for the manager, not the investors), and...

    64-bit vs 32-bit

    I'm not sure one more limitation has been pointed out: On 32bit XP each process (application) can only address up to 2 GB. There's a special trick to get it to 3 GB, but that requires a specially created executable and a custom configured kernel. 32bit XP can address a total of 4 GB, with...

    No notice on IB short buy-ins - Real-time notice needed

    Right now it's very risky to short low volume stocks at IB. I have suspended shorting for low volume stocks, and i know others have too Always expensive to get auto-covered.

    Margin Call - huh

    It all depends on your broker. Interactive Brokers will liquidate you in realtime. Others give you 3 days to wire in the funds. Call your broker and ask what the policy is. Being in denial doesn't help.

    why fade

    it's all a matter of time frame. Example for long: What's "going against the trend" on one time frame, is (hopefully) buying on a pullback on a higher timeframe. Blindly fading current (short term) trend can be deadly. It has to be done in the proper context.

    IB-Commissions Changes

    If it wasn't for Sterling, this would be a very attractive offer, and something I'd consider. But everyone i know who uses Sterling complains almost daily, SW is slow, API is horrible, and the API support is non-existent. If you considered adding FIX, you would attract many more of the...

    Need 2 etf's that nullify each other for SIPC.

    another choice: buy SPY and sell ES you get to collect dividends on SPY and the premium (though small) on ES

    New Symbol for ER2?

    at IB i think it's supposed to be "RUT", but the choice i get makes no sense.

    Combining multiple systems

    Back to the original post: In my experience the real value of running multiple system is the ability to code simpler systems. In stead of having multiple filters for all sorts of conditions, I find that I do better by having different independent systems exploit each type of entry condition...

    Bset Number of Trades to Judge System Performance

    It's ideal if you can have different instruments as well. I've found, however, that systems that work well on stocks, rarely work well on currencies. So while theoretically a good idea to test across all asset classes, my experience is that this rarely works.

    Dumb question about internet speed, as well as Shaw Nitro

    more important than raw download/upload speed is latency, imo. 400kbit/sec is a lot of orders per second, so i doubt that this is the problem you're having. Dedicated lines, such as T1s, often run with significantly latency than a cable modem or DSL. DNS servers is another slow point...

    IB disconnections

    I suggest you switch to the JVM that IB supports. They are pretty clear on their web site that they support JVM 1.5 (they don't list JVM 1.6) I'm on JVM 1.5 and generally TWS works fine. Everyone i know who've tried 1.6 end up switching back to 1.5 for a variety of reasons (connectivity, UI...

    Bset Number of Trades to Judge System Performance

    It's entirely a function of the complexity of the system. If you have just few entry filters, then 100 trades are probably enough. If you have more, then very quickly you'll need 1000s of trades. In my experience, the only realistic way to obtain good statistical coverage is to run the same...

    Raising money - what am I doing wrong?

    Generally, you'll have a very hard time attracting any money unless you have at least a 3-year documented track record of consistent returns. We all have a few months that are especially good, so that you made money since April doesn't count for much if you want to raise funds. Just look...

    Measuring Choppiness

    My favorite chop-index is calculated as follows for e.g. 10 periods (close-close(10))/sum of individual bars (O-C) range That gives you an idea of how much of the 10bar move was noise vs. directional. You can also experiment with squaring the distances, using absolute values etc.

    can someone tell me what happened here? IB

    If you want the closing print, you have to use a MOC order. A DAY/MKT order simply executes when you place it. There often is a significant difference between the last print at 15:59 and the official close.

    Stealing another trader's TA system

    It's very likely another good trader can guess the essence of your system. A bigger risk, in my opinion, is that the prop firm analyzes your trading as they have all the data. There are a few well documented examples where good prop traders strategies turned into training material offered by...

    Mind Tools

    For pulse, i used one of the wrist band blood pressure/heart rate monitors you can get at any drug store or Amazon. I've recently switched to http://www.heartmath.com/. That's what I use now.

    Mind Tools

    Here's a technique that worked well for me when i started out. I noted that I trade worse when I was stressed out or anxious (typically due to one or more losing trades). I started monitoring my pulse and chose not to enter new trades if my pulse was above 75-80. Just monitoring my pulse gave me...

    IB TWS P&L wrong

    I've seen the problem with positions spanning multiple days. I've noticed that today's unrealized P&L sometimes seem to be based off a print after the close of yesterday.
