How a Darvas channel becomes a complete entry and exit procedure

The channel is not yet the system

A price-channel is a box whose top and bottom are fixed from highs, lows, and a lookback so later prices can confirm or invalidate the structure.

That geometry alone does not decide when to enter, when to stand aside, or where the stop-loss sits. A stop-loss is a pre-placed exit that bounds the loss before a trade is opened and stays in force while the position is held.

Editorial view: a Darvas box becomes a breakout-system only when a channel break, that stop, and an abstention rule are written as one testable sequence.

Build the box in two steps

A Darvas-style channel is completed only after a high setup is followed by a later low setup, so the box is a two-step construction rather than a single bar pattern.

The lookback that defines the critical high, and the three-bar extreme used to lock a side of the box, are explicit construction inputs rather than discretionary chart marks.

Same box, different switches

Classic, modern, and breakout styles share the same box geometry and differ only by which entry, next-day exit, ghost-box, and volume switches are turned on.

Editorial view: those switches are how the same price-channel is turned into different complete procedures, not a change in how the box itself is drawn.

Place the stop with the box

The default stop sits at the box floor. A ghost-box rule can lift that stop in whole box-height steps after price travels more than one box height above the top.

Box height can be padded: a top trigger slightly above the ceiling and a stop slightly below the floor are used to reduce false breaks of the channel.

Write the cases that do not fire

A volume-gated entry requires a close through the trigger plus volume above a short average times a factor, otherwise that style does not fire.

The breakout style can require a prior close under the box floor, then a later close over the top, before a new box completion is allowed to arm the long.

Editorial view: those unfired cases are the abstention rule. They belong in the same procedure as the entry and the stop-loss.
