in E-MINI trading when it goes right right up, y not put money on it to go back down 2 points, no matter how long it takes to get back down?

I'm not sure exactly what you are asking, but if you are referring to e-mini's in the currency exchange market, it is generally a retail instrument offered by some currency brokers such as FXCM and others. An e-mini is 1/10 of a contract, so it gives a retail trader a lower exposure-$10,000 as opposed to $100,000, which is a standard contract. (I know my broker gives me the option to trade any amount, so if I want 1 I type one, 100,000 I type 100,000 and so forth-a "mini" in my case would be created by typing 10,000).Lots of brokers advertising the "emini" will give you huge leverage-200 to 1 in some cases, meaning that if you put in 250 you would have the opportunity to trade 50,000, or 5 eminis. Do not be fooled-in the USD/JPY (JPY/USD for all you academics) 1 dollar buys 123.01 Yen, 1/123.01 gives us a spot rate of .008124, so each tick, or pip, movement is worth 50,000 * .00008124 (add 2 decimals for the yen). Thats 4.062, not an entirely huge amount of money, but on announcements like the Non Farm Payrolls and others, the Tokyo Drift is Fast and Furious-it can move 50 pips or more, and you dont want to be on the wrong side of the trade trying to get out on a 15 pip spread! It can wipe you out. What is considered professional leverage can be debated, but its generally 20 to 1. Thats right, even professional traders, who in many cases have dedicated their life to the trade, trade less leverage than you would think. So in the beginning, I wouldn't even consider going into contracts that are much more than 20 times what you have in the account, but your trading style is up to you. Commodities, futures, etc. usually also have minis, but the above can generally be applied, except its not always 1/10. You said something that sounds like you are averaging down, pardon me if thats not what you meant. Again, your trading style is up to you, but most traders, myself included, would never recommend doing it (even though most of us have done it). If something goes against you, get out. Especially in currencies, because you are not buying anything; merely betting on a movement that in theory, may never "come back," or may wipe you out before it does. Good luck.
