The chart is one month of many

Open a futures platform and search for crude oil. You will not find one instrument. You will find a column of them: February, March, April, each with its own bid, its own ask, its own chart. Every one is a different promise - same grade, same place, different month - and the market prices each on its own merits.

Which one is 'the price'?

The quoted headline price is almost always the front month - the nearest liquid contract. It carries most of the volume, reacts fastest to news, and is what your CFD most likely references. But it is not more real than the others; it is only busier. A refinery buying for next winter cares about a back month, and that month can move on a forecast the front month shrugs off.

The same day, different everywhere

News lands on the whole column at once, unevenly. A storm shutting production this week slams the front month and barely moves next year. A treaty changing long-run supply does the reverse. Watching how a move distributes across the months tells you what kind of news the market thinks it received - which is the curve, and it gets its own lesson shortly.

Reading habits to build now

• Know which month your chart shows. On a futures platform it is in the symbol; on a CFD platform it is in the instrument's specification page, not on the chart.
• Check where the volume is. Near expiry it migrates to the next month, and the chart of the old front month becomes a picture of an emptying room.
• Treat 'crude rose 2%' as incomplete until you know which month - moves of different sizes across the column are the norm, not the exception.

One commodity, many charts. Hold that, and the next lesson - what your platform does to pretend otherwise - will read as the compromise it is.
