First of all, thanks for the comments, I really appreciate the feedback.
RE sharks, minnows & manipulation
Exchange traded products like futures always behave somewhat differently than cash markets or continuously traded markets such as foreign exchange because there is an open and a close to the market. The market that closes, and then the day's profits and losses are calculated, margin calls are made, is going to experience short squeezes or profit taking bahvior as traders square their positions or trim losses ahead of the close.
I would have been much better off yesterday had I took profit earlier in the day ahead of the NY open. As it is I carred 2/3 of my overall long on the way down. I was out of the office for 90-minutes and when I came back we had already lost a lot of ground in the first hour of trading on the NYMEX even though the IPE and ACCESS had been very well bid up to that time.
I find the NYMEX so much more volatile than the ACCESS (afterhours trading system for the NYMEX) or the IPE (now called ICE). I think this is the difference between an electronic exchange and an open outcry exchange. For some reason the open outcry is especially prone to overshoot. The traders' fear, greed, optomism or pessimism must feed off one another's?
I was the world's worst pit trader on the Winnipeg Commodity Exchange. I was not loud enough or big enough to get my orders executed. I had two big brokers stand by me and execute my orders. So I have to admit that your order execution is only as good as your floor broker on the NYMEX, whereas if you trade on the IPE your bid or your offer is guaranteed to be done if the market trades on or through your level.
However, in general, large player's are not trading with their own money, but rather their firm's cash. This creates an assymmetrical reward-loss profile. Simply put, if you make money, you get a big bonus. If you lose money you lose your job, but you can usually get another job unless you're completely useless. Therefore, there is every incentive to take big bets with your firm's money as if you are successful you can translate that into a bonus for yourself, not to mention the best traders get promoted in many firms.
What does that mean? Well, if I am trading with my own money I have to be very careful and pick my entry and exit points well to minimize the size of my stop losses. If it is not my money, I could afford to be more aggressive. So if I sniff around the market and figure out where the stop losses are, I can sometimes push the market in that direction to trigger stop loss selling, for example, and then stick my bids in lower which have a good chance of getting done. If everyone is using technicals and we are all trading off pretty much the same levels then it is not too hard to figure out where the stop loss levels are either. Say, just below the previous low, for example.
So, let's say we were near the bottom and I needed to buy 200 lots. It may be worth my while to sell 100 first. Trigger the stop losses and then be an aggressive buyer of 300 lots below the current market price. Sure I might lose money if I am wrong, but the larger you are the less you care. You take a short term hit which the small trader cannot afford, but in the long run you know this strategy will work more often than it fails.
It is not fair, but that is the way it works, so you have to be aware of it and make sure when you set your stop loss and take profit levels that they are not identical to everyone else's. In general, I sell just below any major chart levels and I buy just above them. Say, 95 and 05 instead of at 00. Then if there is a stop loss point, I set my own stop loss below where I think everyone else's will be. Say, the stop losses are at or below 00 I might put mine at 85 or 15 on either side. The extra 15 points makes a small difference to my P&L and it might keep me in my favored position while everyone else with tight stop losses gets taken out.
Sometimes I think the world is out to punish me personally. I missed so many sell levels this week by 3-7 points. The rallies stopped just short of my sell levels and then it tanked. Disappointing yes. However, you have to buck it up and take it like a man. The market has nothing against me personally. It is just a zero sum game. So my loss is someone else's profit. Therefore, I have to be just a little more clever than the next person. You start out with a 50/50 chance and through hard work you try to improve your luck to 60/40. Then it is all money management. Making sure your profits are bigger than your losses. That takes discipline but a little luck never hurts.
RE one year. Well, let's just say I am in my minnow stage in the energy pond, but overall I have been swimming in shark infested waters now for almost twenty years.

The organized state is a wonderful invention whereby everyone can live at someone else's expense.
