    Buying and selling the same currency

    What is the advantage of this over trading the cross currency directly. (i.e. trading EUR/CHF instead of EUR/USD and USD/CHF, supposing the latter two have a correlation that is somehow tradable)

    Buy QQQQ puts

    If you want to _insure_ this shouldn't be a concern. Insurance means you make steady payments every month (or year) that will protect you against one or two (or possibly none...) disasters.

    Buy QQQQ puts

    I actually have a related question, and hope some option expert can answer it. Suppose I want to insure myself against a >5% drop in QQQQ. I'd buy OTM put options with a strike 5% below the current QQQQ price, at regular intervals (say monthly). I expect many times the options will expire...

    How to hedge against crash?

    I'm looking for some resources on how to hedge a stock trading system against very rare adverse market events. I.e. I'm willing to suffer regular drawdowns in 99% of market conditions. However, in case of say an '87 crash, I want to limit my losses to X%. I know an investor holding a...

    is there way to statistically quantify or find an "edge" in a system?

    The problem with searching for an edge without a clear hypothesis upfront lies in data snooping. I.e. if you would simulate 1000 random walks, some would look like having an edge even though they're completely random. Thus, having a hypothesis upfront is a good starting point. But whenever...

    market-on-open for the nyse

    Isn't it the case if you want to get filled at the official open for a NYSE stock, all you have to do is submit a regular market order prior to market open? http://www.nyse.com/productservices/nysearcaequities/1157623605117.html

    Who uses Zecco.com

    They only offer Market, Limit, Stop, and Stop Limit orders. I don't need market-on-open orders as NYSE market orders submitted prior to the open are supposed to fill at the open, due to the auction process. Zecco routes all orders through Penson. I have never filled out a W-9 and they do not...

    Who uses Zecco.com

    I have a Zecco account and use it for longer term trades, i.e. I only enter/exit positions in stocks trading on NYSE with market orders at the open. It works perfect for me. I also have an account with IB for my shorter-term trades.

    Confidence intervals in strategy performance

    It's possible to compute a confidence interval for any statistic (max DD, profit factor etc.), but I prefer not to rely on normality assumptions (as the formula mentioned above seems to do). I've posted an excel spreadsheet in another thread that uses non-parametric bootstrapping (and hence does...

    Sogo Invest and Zecco trading...experiences and/or thoughts

    At Zecco only the first 40 trades each month are free, after that it's $3.50/trade. I've been trading with them since the beginning, but not as an active trader (i.e. less than 40 trades/month), and am quite happy so far. Other brokers you might be interested in, with low per-trade...
