Momentumdraws in its own pane

A slow blend of two long rate-of-change readings, designed for spotting major lows. On a daily chart it reads as patient momentum.

On this chart: 14 + 11 ROC, 10-period WMA.

Edwin Coppock built this for monthly charts in 1962: sum a 14-period and an 11-period rate of change, then smooth with a 10-period weighted average. The design goal was identifying the turn out of bear-market lows, and its historical record on monthly index charts is what made it famous.

The classic read is the turn: the curve bottoming and hooking upward from below zero. On daily bars everything happens proportionally faster than the monthly original, so treat its signals as swing-scale rather than cycle-scale.

A bottoming Coppock on a beaten-down quality name describes the late stage of a decline — the phase where fear is still priced into the options but the selling pressure is demonstrably fading. That combination is the textbook environment premium sellers wait for.
