genesis : how do I play futures on corn newbie

Maggie Tucker : Buy Low, Sell High -go Long Contract if prices going up or Call Options if Purchasing Options if price is Going Up.  Or if Price is Going Down - You would Short the Contract or if Purchasing Options you would get a Put Option.  Always get a Contract Farther Enough Out  on Expiration Date so You Don't Actually Have To Take Delivery of the Product.  On Options You Don't Want them to Expire Worthless.  Hope This Helps
