It doesn't matter. But put simply, the dome is like an invisible/transparent paper that sits on the exchange without sitting on it (a bit like a transparent mirror). I think I butchered that one, however, the point is that it is not important when it comes to trading. How or what the connectivity, that falls in the field of computer engineering, not trading. All you have to do is enter the trades on the dome, and create a chart from the data supplied, with either your software, or, one built into NT. NT is Ninja trader. Sorry.
I don't think this is super important. Maybe this helps you understand the esignal/DOM/order stuff. I don't need any comments unless you really want: http://www.ninjatrader-support.com/automatedTrading_Esignal.htm -Stephen
Too dangerous, for the individual. Got to realize that you are trading against someone/thing else. Black boxes are most likely programmed to hit stops.
A black box is another word, I guess, for automated trading on the biggest scale. Consider 1000 or more contracts that need to be bought or sold in a short time frame. It would be impossible for a human to do so, so the computer is pre-programmed to do the buying and selling in an efficient manner. Anyway, the charts are only good to look at, the money/profit made from trading is derived from trading skill + experience + luck.
Does anyone have a site that CLEARLY explains ALL the types of orders. It should include the basic ones including the 'negative limit stop limit order'. -Stephen
