Your remarks would have been more profound had you spelled it "sown" rather than "sewn". In my opinion.

Hire programmers who have read and understood and, ideally, implemented & tested the IEEE spec for floating point arithmetic. (link). Then tell them to store all values and perform all arithmetic in "double" (64 bit) precision floating point numbers, and to use the rounding modes and the...

The New York Post got it wrong? They erred on the side of sensationalism? Unthinkable.

I think Wealth-Lab Developer can do it too.

ASSUME that you have chosen a preliminary design (which is a point in N-dimensional space, one coordinate for each of the N system parameters). One thing you could do, is simulate other designs that only move each coordinate, at most, +/- 15 pecent away from the preliminary design. (or 20...

Write a list of the submeasurements you want to include. Next to each item, write down whether Larger Is Better, or Smaller Is Better. For example, next to "Compound Annual Growth Rate In Percent", write "Larger Is Better". Next to "Length of longest drawdown in weeks", write "Smaller Is...

Here's some general purpose advice: Do what you think is right. Mr. Soros is doing what he thinks is right. If you have a different opinion, do that and ignore Soros.

If you want serious diversification into lots of global futures markets, Pinnacle isn't the best choice. Mostly they specialize in North American and Western European futures markets. Among the many futures contracts not covered by Pinnacle, areSwiss Govt Bond @ Eurex ("CONF") BUXL @ Eurex...

That son of a bitch Claude Shannon has beaten you to the punch. Google "Shannon's Demon" to find his 1966 method for making money from a random walk. Professional money managers use variations of Shannon's Demon today. But they call it "optimal rebalancing" and/or "volatility pumping" to...

Yes there is an optimum way to manage the account. However it is different for each trader. For Trader A, the optimum plan is to withdraw 10% of the account each quarter. For trader B, the optimum approach is to add $500 to the account each month. The trick is to decide what is optimum for...

Find a tradeable with a very wide bid-ask spread. I suggest Propane futures at NYMEX (the nice people who also let you trade Crude Oil). Perform the following steps 3 times a day:Flip a coin. If heads, go long 5 contracts at market (pay the ask). If tails, go short 5 contracts at market...

There are several ways to define the "volatility" of a futures contract. Different definitions will give rise to different measurements, and result in different rankings. "Volitility" might conceivably mean:"Implied Volatility" (expressed in percent) of an at-the-money call option on the...

Why? Because you appear to have tremendous conviction on the trade. Which expiration? Your decision.

Of course not. Sit quietly for 120 seconds and ponder the question "Name 3 types of traders who would not be grievously wounded by 9/11 part 2". If you need inspiration, thumb through the tables of contents of the Market Wizards books and ask yourself "What happens to this strategy in a 9/11...

Howard Bandy's book Quantitative Trading Systems (link) . . . {alternate link, at Amazon} agrees with you. On pages 313 to 315 he lays out his conclusion Stops Hurt Systems. It includes this little snippet:The worst way to exit is the maximum loss stop. For one reason or another you may...

Load up some 1 minute bars (which might be the appropriate granularity, but use your own judgment based on the system's characteristics). For each bar, plot a dot on a scatterplot. Let X = (volume of this bar) and let Y = (price change, from last bar to this bar). Use your own judgment to...

Buying puts offers greater leverage. From Stanley Druckenmiller's interview in The New Market Wizards (p. 208):George Soros came into my office and we talked about the trade. "How big a position do you have," he asked. "One billion dollars," I answered. "You call that a position?" he...

When selling naked options, or when selling option combinations that get you short the wings, one possible scenario to consider is a very large price gap against your position. If you use "distance to my stop price" to calculate "risk", remember that the underlying can gap waaaay beyond your...
