A two-stage momentum-shift and price-channel process

A two-gate decision process

This editorial reading treats the archive workflow as two gates rather than as a single entry rule.

A momentum-shift is a change in weekly closing price that exceeds a set percentage threshold in either direction and is used as an early alert rather than as proof that a trend exists.

A price-channel is a band built from highs and lows over a fixed lookback that marks when price has entered a new series of highs or lows and supplies candidate support, resistance, and stop levels.

In this editorial framing, the weekly shift is a falsifiable hypothesis. The later 30-day channel break is what converts that hypothesis into a hold, a protective-stop plan, or a pass.

What trend-following waits for

Trend-following is a procedure that waits for a series of higher highs and higher lows, or lower highs and lower lows, then stays with that series until evidence appears that it has ended.

It enters only after that series is underway, then stays until clear evidence appears that the series has ended. It typically forgoes buying bottoms and selling tops, treating a sustained decline as a short or a pass and a sustained advance as a hold until prices level or reverse.

Why an early momentum-shift is noisier

A momentum-strategy is a procedure that treats a large enough change in weekly closing price as a shift signal meant to catch the start or end of a move earlier than a confirmed trend.

Momentum-shift methods aim to catch the start or end of a price move and tend to produce more volatile outcomes than trend-following, including false entries on short-lived countertrend rallies.

A countertrend-rally is a short-lived advance inside an intermediate decline, or a short-lived decline inside an intermediate advance, that can trigger an early momentum-shift entry that later fails.

Gate one: the weekly shift

A weekly close that moves at least 4 percent in either direction is treated as a momentum-shift signal and can appear before a 30-day channel break.

The 4 percent weekly threshold is a convention rather than a unique constant. 3 percent and 5 percent can be substituted, with a lower threshold generally increasing signal count and a higher threshold reducing it.

Gate two: the 30-day price channel

A 30-day price channel is used as a trend-following device that records new highs and lows and treats a break of those bands as an initial trend signal.

The combined procedure uses the weekly 4 percent shift as an early alert and the 30-day channel to confirm direction and to locate protective-stop areas at successive channel highs or lows.

A protective-stop is a planned exit placed at a recent or prior channel high or low once a move is underway, tightened or loosened according to volatility and risk tolerance.

When the channel does not confirm

If a momentum-shift alert is not later confirmed by a new 30-day channel break, the move is treated as less established and the position may be closed until the next setup.

In editorial terms, that outcome is a pass: the early hypothesis is set aside rather than treated as a completed trend.
