EIA crude oil inventories: the Wednesday report and CL order flow

What the report contains

EIA collects weekly data from refiners, terminals, pipelines and importers. The headline is the week's change in commercial crude oil inventories, excluding the Strategic Petroleum Reserve. The report also gives stocks at Cushing, Oklahoma, the delivery point for NYMEX WTI crude futures, stocks of gasoline and distillates, refinery inputs and utilization, domestic production, imports and exports, and product supplied, a proxy for demand.

Weekly figures are noisy. A tanker arriving a day earlier or later can swing imports and stocks by amounts that dwarf the underlying trend, which is why four-week averages and seasonal comparisons are used.

Figures CL traders compare

Why crude futures react

A larger-than-expected draw suggests tighter supply relative to demand, a larger build the opposite, and CL reprices on the difference with what was expected. The API survey released the previous evening already shapes expectations, so the EIA surprise is measured against both. Products can tell a different story from crude: a crude draw with large product builds may reflect refiners running hard into weak demand. The reaction's sign and size depend on which figures surprise and on the market's current concern.

Order flow in CL around 10:30 a.m. ET

Crude oil futures show one of the clearest pre-release patterns of any weekly event. In the minutes before 9:30 CT, the heatmap usually shows resting size near the inside thinning and the spread widening, and the DOM numbers shrink. At the release, the first trades can sweep several levels in a fraction of a second.

The first minute's high and low often act as references for the rest of the session. The footprint then shows whether aggression continues through the extreme with delta confirming, or whether large passive size absorbs it and price rotates. Because the headline can be contradicted by the products or Cushing figures, reversals within the first minutes are common. MCL, the micro contract, trades the same underlying with a thinner book, so the same move can look more abrupt there.

In Senzoukria

The calendar row for crude oil inventories is described as “Oil inventory — WTI/CL driver.” The Quant mode card classifies it in the Energy family and lists CL and NG first among the contracts concerned, with the US index, rates and dollar contracts after them. With the CL / MCL preset chosen in the news wire, “What moves my session” narrows to US releases in the next twelve hours.

On a Rithmic account with order-by-order depth, the heatmap's Liquidity Tracker column shows, level by level over the last 30 seconds, whether the liquidity that left the book was withdrawn or executed, which is exactly the distinction the pre-release thinning raises.
