For instance there are STOP, Market, Limit and MOC orders what is that each of them mean and when should I use them.

ohhh... careful... futures is one of the few places you can actually lose more than the amount you invested! If you don't know what these orders are, then I would advise that you trade stock for a while, to get used to them. Stocks are bad enough.. but futures are like stocks on crack & meth & whatever other drugs make you crazy!anyway:Stop: STOP! get me out! the price is going down and I want OUT ! ( so the price is 10 right now.. you put a Stop at 9, so that if it goes down to 5, you got out at 9! but as long as it's above $9... you stay in, and make lots of cash)Market: Slay me! take all my money, I don't care! i want it NOW! ( Market orders say - I know what I want, I want it now, just give me the best price out there, I don't care what the price is ) Limit: Wait! I know I want it... but c'mon, I don't want to pay more than $12 for it! ( Limit orders say you'll take it for $12 or less... but not a penny more )MOC: forget it, don't do it, this one is just plain dumb... worse than Market, this is Market On Close.. ( that means I want some, but wait until the market closes and then buy me some... I REALLY don't give a hoot what it might cost me! )Again: if you don't know what these order types are... you need to trade stocks for a year and forget about Futures for now... or you'll be forgetting about all the money you used to have..... :-)Good luck!
