Here's a little tiddy about how the price if Crude actually changes.
Once you read and digest this post I hope you walk away thinking two things:
1. Yeah, that makes sense.
2. There are a lot of benefits to be had by monitoring Program Trades.
It has been our observation that much of the assent of the price of Crude occurs in the pre-market.
We define the 'pre-market' using an EST (Eastern Standard Time) clock from 8:00 a.m. to 10:00 a.m. when the NYMEX pits open for business.
This is a loose definition as what we are about to illustrate can happen almost anytime but seems to re-occur in around this time period.
A Little Background
Consider this, if Buy Programs usurp the supply of futures contracts, thereby increasing price, would a series of Buy Programs that were initiated in a period when there was dramatically lower liquidity (the pre-market) have the same effect on price if they were fired off in a period of high liquidity (when the NYMEX pits were open)?
If you are a subscriber to the Law of Supply & Demand then no. If the increase in demand is constant but Supply is less, then price will have to move more sharply to accomodate demand.
Thus, if one were so inclined and had the capital they could Buy, Buy, Buy in the pre-market and push the price of Crude up $3-4 with significantly less effort if they tried this antic when the pits are open.
Crude moves to a record $139
On Friday, June 06, 2008, the forward Light Sweet Crude contract ran up to $139.
What is interesting is that the move up occurred in 2 distinct $4.50 moves.
One in the pre-market and one into the close.
Wouldn't it have been nice if you had participated in the pre-market move as opposed to the move later in the day and been able to turn off your computer and go to the beach with your kids as opposed to watching the market all day wondering?
What does the effect of Buy Programs in the Crude Market looks like using TLA Software?
You will notice in this chart that there are two primary moves in Crude this past Friday, both for an upward move of around $4.50. One occurred in the pre-market and one occurred after lunch:

In this next chart you can see MacDaddy (an algorithm that monitors the strength and momentum of Program Trades) plot a series of 5 small to intermediate Buy Program Trade Runs which push the market up $4.50.

In this final chart we can see 2 very substantial Buy Program Trade Runs firing off after lunch which lift the market the same $4.50 as the smaller Buy Program Trade Runs were able to lift the price of Crude in the pre-market.
So, what does this all mean?
The pre-market action is ripe with information. Some smart guys knew when to initiate buying. They knew that they could fire off a bunch of Buy Orders and chew through the limited amount of futures contracts in inventory in the pre-market.
The net effect of this was to lift the market. What can a Fundamental Analyist say about these types of price moves? Was there a dramatic shift in Crude Inventories before during or after these price spurts? Did a another war flare out in the Middle East? Did the dollar drop some more? Nah...Price, in the short-run, which is what most traders seem to care about, is predicated on the Buy and Sell Programs, nothing more fancy or elaborate than that.
Hopefully this example gives you some insight into this approach.
Happy Trading.
