first off, you probably cant.........
2nd off,,,,,,, you can buy CALL options..... this limits your risk to the amount that the option cost...........
lets say your looking at march corn (which i am)..... its currently at 402 after the overnight session dropped 7 cents......... and all you know is that corn is going to go up.............. you would not want to simply buy it, with only 2500....... your margin will be about 1100.......... if it goes 20 cents against you (back to 382), what will you do then......... your account will be at 1500 and 1100 will still be margin...... you can stay in but will you blink........ there is a lot to this.........
there is a gap that needs to be filled, ending at 396, i happen to know a lot of buy orders are sitting at 395....... to get long once this gap is filled..
here is my analysis of march corn.......
Longterm trend is UP
shorterm trend is sideways to lower
we have a high yesterday of 410.5 to consider, we have a low yesterday of 404............ over night traded lower, its going to open this morning at 402 (because thats where the night session ended)...... it closed yesterday at 409, so its going to open down 7 cents from yesterdays close, are you with me........
this tells me, there are still sellers in this market, especially early today and i wont buy today unless we trade thru the high of 410.5 yesterday.. if it breaks 410.5 today, ill try and buy the first pullback....... if this doesnt happen, then ill never buy today......
i think the market will try and trade lower today, maybe down to 395 area.. if this happens -- a possible short term sale could be executed but id be hesistant to stay overnight (short) in this market...........
today looks like lower early, then we shall see..........
ive got a cattle and hog trade working, but ill check in and out..
