Copper (HG) September (U) contract study: year-by-year results, the day-by-day shape of the move and where highs and lows printed.
Contract Almanac · Copper (COMEX)
Every September copper contract 2010–2025, measured over its tenure as the lead contract · Typically leads Jun 27 – Aug 27
The September contract holds copper from late June through late August, after the summer seat’s damage is done, and its file is the quiet convalescence: 6 of 16 higher with a nearly flat average, small magnitudes, and late lows. Copper’s late summer has mostly been a market catching its breath.
Each year is one contract, measured from the open of the day it took over the lead to the close of the day it handed off, the same roll convention used across all Traders Brief research. A copper contract holds the lead for roughly two months, and the March and December contracts closer to three, so tenures run 40 to 70 trading days, far longer than an energy tenure — these are seats, not months, and the day counts read accordingly. All highs and lows are the contract’s own trades, marked by trading day of the tenure, not calendar day.
