A $1.00 move in crude is enormous. If it moves $15 in one day, you will have bigger problems than a futures trade. still, I was not aware there was a daily limit or a contract limit. 50 cars=20 cars regular contract, which is not what I would call size in this market. Still, for most daytraders you cna make or lose a hideous amount of money on half that. For someone not used to this market, I would say start at no more than 10 contracts on the mini. The key to this market is the weekly inventory data, reported tuesday afternoon by the API and Wednesday morning by the Government. Nat gas data used to come out wed at 2 butI think that changed in the last coupel of weeks, now theyare reported on thursday mornings, I believe. Stand aside ahead of the gas data, as it can be volatile.
I reiterate that crdue is a great daytrade market, much better than currencies and easily equal to bonds or index futures.
