This strategy was decoded from a public trading video but did not clear Strategy Decoder's codifiability bar: the extraction could not pin the rules down precisely enough to be turned into a reviewable specification. It is kept here as a reference post-mortem rather than as a strategy you can trade or backtest.

Why this strategy was archived

The Coppock Curve is a long-term momentum oscillator built from a weighted moving average applied to the sum of two Rate of Change readings. Designed for stock indices and traditionally read on a monthly chart, it was conceived to flag major bottoms rather than to time short-term swings — a signal generator with a deliberately slow clock. This entry decodes Quantified Strategies' short "Coppock Curve Trading Strategy (Backtest & Rules)", which frames the indicator the way it should be framed: against S&P 500 data, with backtesting as the arbiter.

**Why this entry is archived.** Our extraction captured the structural layer — the Coppock Curve itself, its Rate of Change and Weighted Moving Average components, and the stock-index context it is applied to — but not a rule set complete enough to automate. The signal conditions are referenced rather than specified: no captured lookback parameters, no explicit trigger level or crossing condition, and no timeframe attached to the setup, which matters unusually much for an indicator whose behavior changes character between monthly and shorter charts. Coding it would mean filling those gaps by guesswork, and a strategy we cannot reproduce faithfully does not belong in the active catalog. The short-form format compresses a backtested idea into seconds; that is a constraint on our extractor, not a criticism of the video.

**What it still offers.** The framing is sound and worth borrowing: an old, well-documented indicator, applied to the index it was built for, and judged by backtest rather than by a handful of flattering chart examples. If you are researching long-horizon momentum, treat this as a pointer — the indicator's classic construction is public and testable, and the video tells you where to look. For entries where full entry and exit logic was successfully extracted, see the momentum and oscillator concept hubs and the active catalog.

Frequently asked questions

Why is this Coppock Curve strategy archived?

Our extraction identified the indicators and the market context but not a complete, automatable rule set — the signal conditions, parameters and timeframe were not captured precisely enough to code or backtest without guesswork. That places it below the codifiability bar we require for the active catalog.

What is the Coppock Curve?

A long-term momentum oscillator that applies a Weighted Moving Average to the sum of two Rate of Change readings. It was designed for stock indices on a monthly chart, with the aim of identifying major market bottoms rather than short-term entries.

Is the video still useful?

Yes, as a research pointer. It applies a classic indicator to the index it was built for and treats backtesting as the standard of proof, which is the right starting posture for anyone evaluating long-horizon momentum signals.

Where can I find codifiable momentum strategies on Strategy Decoder?

The active catalog and the momentum and oscillator concept hubs list decoded video strategies where complete entry, exit and parameter rules were successfully extracted.
