This lesson opens with The United States Oil Fund and the April 2020 roll.
- What happened
- The United States Oil Fund held front-month WTI crude futures and rolled them forward on a published schedule set out in its prospectus. Retail inflows during the March and April 2020 oil collapse were very large, exceeding $2.2B of net new assets in March and a further $2.6B by 17 April, which pushed the fund toward the CFTC and exchange position limits that cap any single participant's share of a contract. In an 8-K dated 16 April the sponsor said that from 17 April the fund would hold about 80 percent of its portfolio in the front month and about 20 percent in the second month, and over the following two weeks it spread the holdings across later expiries and, on 30 April, extended the roll period from four days to ten. On 20 April, the next session, the front-month contract traded below zero for the first time since WTI futures began trading in 1983.
- The decision point
- The fund's holdings were published daily, its roll dates were in the prospectus, and its size relative to the contract was computable by anybody with a calculator. That combination is the most readable position that can exist in a market: a party that must trade a known quantity, in a known direction, on known dates, regardless of price. Everything else in this lesson is an attempt to infer positioning that in this case simply did not need inferring.
What you will be able to answer
- →What are the three measures?
- →What makes a position readable?
- →How do you compute a footprint?
- →Where are you in somebody's reading?
Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.
It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested
Whether trading ahead of the fund's roll amounted to legitimate anticipation or something worse was debated at the time and is not resolved here. The CFTC subsequently brought an order concerning the fund's own disclosures rather than concerning other participants' conduct. Per P6 this lesson uses the case for its readability point only.
The contract arithmetic in part two uses stated inputs of $4.8B of inflows, a $20 reference price, a 1,000 barrel contract and 400,000 contracts of daily roll volume, to demonstrate the method. Actual open interest, volume and the fund's precise holdings varied daily and are not reconstructed here.
The 80 and 20 percent split from 17 April is from the fund's 8-K dated 16 April 2020; a later 8-K refers to it as filed on 17 April. The four-day roll is ETF Strategy's description of the fund's usual practice, and the ten-day roll is from the fund's 8-K of 30 April 2020, which says the May roll began on 1 May. ETF Strategy also notes that the fund had already rolled out of the May contract before it settled below zero, so the readable trade here is the June roll and the fund's size, not a holding in the contract that went negative. The negative price is from the EIA's This Week in Petroleum of 22 April 2020.
R401-01 uses the same April 2020 period through the negative settlement and a broker's customer losses. This lesson uses the fund's published roll as a positioning case. Two different parties and two different mechanisms in one month, and the split is deliberate. Keep it.
