First, as said before, squaring something then taking the square root has become a standard way of getting the absolute value. The standard deviation formula here is the "bias corrected" version, there's the population deviation formula too that's ...

Diagnosing hardware problems is easy. It's done by bisecting the problem into smaller increments. Start by unplugging all of the drives, hard drive, floppy, CD-rom, etc. Also, disconnect all of the non-cruicial expansion cards (aka everything but ...

Sounds like you think it's the power supply. Why not just upgrade it?

Running a fund and being a private trader are two vastly different experiences. If you're going to start up a fund, make sure you... talk with a lawyer first Otherwise you're going to get hammered by regulation and liability.

Sure, but higher time frames are more "trend efficient" because of money flow and macro conditions. A trend or momentum-based approach is trivially easy to find on the monthlies. The edge lies in choosing the right pairs.

LOL. Mostly it's because people with no experience try to trade the M5. It's trivially easy to be profitable in forex by trading the monthlies. Of course that means you can't run with a jillion:1 leverage, either.

Using other distributions. See the links I posted earlier. Are you familiar with the Black-Scholes equation? url Altho it's been known for some time that this model misprices things a little bit. There's a lot of research in that area, it's nutty ...

Nod. A reversal on the 15 minute means maybe a 20 pip change in most cases. It's a short term retrace. There are some 5 minute signals that occasionally spell massive changes, but they show up on other TFs soon enough anyway. By contrast, some ...

I'm guessing you trade on a higher timeframe than intra-day, and you're probably looking at moves that last several days or longer, versus several hours and shorter.

Ok. I've not found any pairs that do. However it seems more of a timeframe issue than a pair issue. Different TFs trend to different distributions it seems.

It never had them. It's a logistic distribution. Later tonight, if I get time, I'll post some graphs. For now... url And url And url

Apples to oranges. You can track the performance of trades, ie: returns, because returns DO (at least usually) follow a normal distribution. You cannot work with price data using a normal distribution. Well, you can, but it will have an abysmal ...

Anyone doing a regular STDEV on forex data is going to get trashed by the market. The market doesn't tend to a normal distribution.

Traditional standard deviation calculations don't work in forex because the distribution isn't Gaussian. Typically, data is positively skewed (positive long tail). Additionally, when doing means you usually want to aim for the geometric mean, rather ...

Well those aren't exactly the numbers. But I've tested this, and it only seems to affect some systems. As people have said before, bringing your SL up anywhere too soon reduces the "wiggle room" and can cause trades to stop out. At BE, it means you ...

You're going to find that a lot of times price will retest S/R levels before moving on. If you jump in and move SL to BE too soon, that test will knock you out. That's, personally, why I don't move to BE in one single step... I move to half-risk ...

Uhm, no. That's not the way it works. When you move an SL to BE, you aren't opening up a new trade. You're adjusting the SL of the current trade. The analogy of opening up a new trade, hence losing pips, is incorrect. What it does, however, is mess ...

As I said earlier, yes.

That's because your video cards do the work there. If you have a lot of data imported into MT4 and load several of those charts, it can max out the ram on a smaller machine.

I've got an AMD quad core Phenom II 955 BE, overclocked to 3.6ghz, with 8gb ram. I do a lot of testing, everything from proprietary platforms and data stores to MT4 and public data. I'm running linux (ubuntu 10.04), with virtualbox. MT4 by itself ...
