Exit rules before entry: trendline, support, and stops

A buy story is not a sell rule

The source argues that traders can usually justify a purchase with a story or an oscillator trigger, yet often have no written rule for when to sell. That gap is the winner-loser-game: amateur results are driven more by unforced exit errors than by a shortage of buy ideas.

An entry-exit-system is a written pair of if-then rules that specifies both how a position is opened and the exact chart or risk event that closes it.

Why a fixed drop from the buy price is incomplete

An initial protective exit of 8% to 10% below the purchase price is described as incomplete because it ignores price level, bid-ask width, and ordinary weekly volatility. That band is a percentage-from-entry-stop: a fixed drop from the buy price used as an initial protective exit, not a complete sell rule.

A trendline break as the written sell signal

A rising market is defined as higher highs and higher lows. Connecting those lows forms an up trendline, and a lower low through that line is treated as a sell signal.

A trendline is a line connecting successive higher lows in an advance, or lower highs in a decline, so a later close through the line can be treated as a defined exit signal.

Support failure as an alternative exit

Pattern support and familiar chart formations are offered as an alternative exit trigger so a position can be closed when structure fails rather than when a narrative expires.

Support-resistance is a previously observed price shelf or pattern floor whose break is used as a sell condition, distinct from a percentage drop from the purchase price.

Accredited Home Lender as a sell-first case

In the Accredited Home Lender case, combining a fundamental deterioration with an August 2006 trendline break is presented as a usable sell point, after which a later break coincided with a rapid loss of remaining gains.

By December 2006 the same name's earnings growth is described as already negative after price had fallen 50%, which the source uses to argue that sell timing should rest on technicals while fundamentals serve as an early warning.

A mortgage-industry index is described as having topped in December 2004, about six months after that stock's earnings-growth peak, as sector confirmation of trouble ahead. That pairing is the technifundamental workflow: watch earnings or sales deterioration as an early warning, and still time the actual sell from price structure.

Bind the sell rule with a stop placed in advance

The source says prudent operators can place stop orders in advance at a projected trendline or a marked support price so the exit is executed automatically.

A stop-loss is a precommitted price or exposure bound that closes the trade when hit, instead of waiting for hope, a new narrative, or a later fundamental confirmation.
