This may sound shallow or trite, but it always amazes me that the numbers of buyers and sellers in the e-mini S&P future on a given day are always equal. Okay, there may be some arbitrage, but there isn't always, and there doesn't need to be.But suppose, at the beginning of the day, 10 people set out with the intention of selling no matter what, and 5 people set out with the intention of buying, no matter what. By the end of the day, there will either be 5 prints or 10 prints, but certainly not 10 sells and 5 buys.At the beginning of the day, it is not known what will trigger 5 sellers to postpone, or 5 buyers to accelerate. So, in my opinion, the number of buyers and sellers is not so much discovered, as it is manufactured. The number of buyers and sellers must be made equal.The way I see it, there is not so much actual flexibility in the underlying demand for, or supply of stock in different timeframes. Therefore, the job of the ticker, is simply to keep painting pictures until the number of buyers and sellers is equal. See what I mean?I guess what I am saying, is that the position you hold, will not be dictated by the information you know. Rather, the number of sellers necessary to balance buyers, will select who should hold stock, among people who know or believe different things, or something.See, your information is constant, but your position must be flexible. Therefore, your information cannot dictate your position. It's like conservation of entropy, or something. The marketplace must select people to be wrong, or something. Ugh, I just about give up!It's like suppose there are 10 buyers and 20 sellers at 50. The market dips down to 45 for one second, which shakes out 10 sellers below 50, who sell to 10 buyers at 45. The market can immediately bounce back to 50, and be at equilibrium again.Maybe I am overblowing the significance of this, but it seems interesting that you may be a buyer at 45 no matter what. But whether you actually get to buy at 45 is the market's choice. So the market has this endless supply of people waiting to be wrong.And I know this is just a rehash of the old trader's lesson that it doesn't matter whether you're right, it matters whether you're right the subset of times you actually get filled. But the point is, the marketplace must manufacture ideas at random to reward and penalize.It's like, if the market needs a seller, the chances it will do the unique thing that cause you to sell are not 10%, they are 100%. I guess I am just saying the market churns out ideas to manufacture counterparties, the number of counterparties doesn't move the market.Okay, now I almost completely give up. MP
