Good grief, you're either an outstanding troll, or, well, I don't know. What you think the words "simulated trading" that are emblazoned on every page and every chart mean?
Ok, I think the IB Demo is connected to the network of the Market Maker education school or so. Somehow it looks very realistic, but I'm no more sure about how the IB demo internally really works. As said it looks very realistic. If you want to test it yourself you can find TWS here, there are versions for Win, Mac, and Linux. I'm using the Linux version. It's a Java application: http://www.interactivebrokers.com/en/p.php?f=tws tab Software/Standalone Downloads/...
And I thought that I have seen it all on ET over the years. But trying to avoid MM games that are played in real market while trading sim is something else. If OP meant this thread as joke, have to say I had a good laugh.
Hello! You made a fundamental mistake of how markets work. "Market maker" isn't one single entity as a whole. Big guys do compete with one another. A market doesn't work like a casino where players are always against the banker. What truth is the majority must be the losers because market is a negative sum game. But it doesn't mean your loss must be market maker's gain. It could be anyway (another player, an investment bank, or whoever you can imagine).
To simplify the case let's assume there are 4 traders in the market. Market maker A, individual A, individual B, individual C. Assume market maker has perfect information and complete control on the market. Individual A is on the buy. Individual B and C is on the sell. As a "godly" market maker, you still can't make all individuals lose. Either side must win. The rule is the majority will lose i.e. the selling side. What if there are more than one competing market makers? Things aren't as tightly controlled as you imagine under the hands of market makers. The bigger the market the harder the market maker controls it. What they target is the general public. You are just a needle in the haystack. You win if you know where the "smart money" stands. Who really cares a tiny person like you trade? They won't spoil their big plans just to make you lose. After all, Lehman did fall down. Big guys are never God!
