Testing horizontal price channels with stops and scale

Editorial view: treat a sideways price channel as a draft hypothesis, not a finished signal. The archive workflow asked for chart scale that made the walls coherent, an upswing off support, a stop-loss under that floor, an exit at resistance, and a liquidity filter that the range could actually be traded.

  • Finding a horizontal channel was a visual search for repeated highs and lows, not a concealed formula, and favored names that had already printed peaks usable as resistance.
  • The same support and resistance lines looked doubtful on a one-year chart and more consistent on a three-year chart.
  • A channel long waited for upswing confirmation, used a stop-loss under support, and treated resistance as the planned exit.
  • The liquidity filter used about 10% volatility, typical volume of 50,000 shares or more unless the bid-ask spread was only a small part of the range, and still did not guarantee a fill.

Treat the channel as a hypothesis

Editorial reading: a sideways price channel is a draft hypothesis, not a finished signal. The same walls can look false on a short chart and coherent on a longer one.

In the archive, a long was described as live only after an upswing had started from support, a stop-loss sat under that floor, the planned exit was at resistance, and a liquidity filter suggested the range could actually be traded.

A visual search, not a hidden formula

The process for finding stocks in a horizontal channel was described as a visual search for chart patterns rather than a concealed formula.

Channel construction favored names that had already printed one or more peaks that could serve as resistance. Those prior peaks and troughs were the support and resistance structure: a floor, an alternative floor, or a ceiling that could mark entry, invalidation, or a planned exit.

Chart scale can change the picture

Chart scale is the lookback window used to judge whether the same support and resistance lines form a coherent channel.

On one worked idea, a one-year view made the same horizontal channel look doubtful, while a three-year chart made those support and resistance lines look more consistent.

Confirmation, stop-loss, and a planned exit

The stated long process was to confirm that an upswing had started, use a protective stop-loss, and exit when resistance was expected. Upswing confirmation meant waiting until price had started rising from the lower boundary before treating a channel long as active.

The stop-loss was a predefined protective exit placed below chosen support so a failed channel long stayed bounded.

On one worked chart, reconstructed support sat near 6.50 or 6.75, the stop-loss at 6.25, and resistance as the long exit at 8.00.

The liquidity filter

The liquidity filter checked that volatility, typical volume, and the bid-ask spread fit the width of the support-resistance range.

Stated screens included about 10% volatility to span that range and typical volume of 50,000 shares or more. When the bid-ask spread was only a small part of the support-resistance range, typical volume was allowed to fall below 50,000 shares.

A spread check did not guarantee liquidity. Filling the intended size in one example implied buying close to 1,000 shares.

How often the rules left a long in place

Using those confirmation rules, a reviewer would have been long on only two of the first twelve names examined.

In a later set of twelve channel ideas, two had turned down, nine were still sideways, and one had gapped up.

Franklin Covey three-year daily close versus the $8.00 / $6.75 channel

Stepping back across three years of daily prices, the same $8.00 ceiling and $6.75 floor sit on a long base after the 1999 collapse from the high teens, which is why the service treated the band as tradeable; that floor then gave way in the summer of 2001. The path is read from the three-year daily print; the two walls are the dollar levels named in the review.

Closes are approximate readings from the printed daily chart, so turning points are rounded to the nearest tenth of a dollar. Resistance at $8.00 and support at $6.75 are the levels stated in the review, not interpolated from pixels. The source marks 27 April 2001 with a vertical line.
