How can anybody claim that overoptimization is bad? It is simply impossible to cherry pick history data to look good. I mean, who is stupid enough to test their software on ONLY one set of data just to look good? I am sure, everybody is smart enough to test their software on multiple sets of data

I know some people recommend a minimum of 5K or 10K in your traders account. What's your minimum?

This may seem like a dumb question, but here goes. (I am a programmer, but new to MT$, so forgive the question if it is dumb.) Last night I was modifying my EA code from a directory on a flash drive, compiling it there, and then copying the .exe to the MT4 experts folder. Today, that doesn't seem...

In another post I complained about modeling quality itself. Now I found that the modeling quality is not constant for the same test that is run multiple times. This ultimately proves that the tester is not reliable (build 222). 1. First, let's make sure that we delete all history and tester cache: 2...
