Gated entry and scale-out after a climactic selloff

What the case records

This archive case study describes a historical workflow for a countertrend long after a waterfall decline. The long is withheld while price is still falling.

TradersWeek editorial reading: the same material is clearer as three successive gates. First classify the decline. Then allow entry only after a defined reversal trigger. Then reduce the position at successive moving averages so the bounce is judged as one entry, stop, and exit system rather than a single prediction.

Classify the decline

A climactic selloff is a fear-driven decline with a run of expanding down bars, rising volume, a near-vertical path, and wide separation from the moving averages. In the archive workflow it is identified when at least five successive down bars expand in size, volume rises, the path is near-vertical, and price stands well apart from the moving averages.

A power trend is a persistent down move with more uniform bar size, a shallower slope, and prices that stay close to the moving averages. It is identified by more uniform bar size, a shallower roughly 45-degree descent, and bars that stay near the moving averages rather than running away from them.

TradersWeek editorial reading: this first gate is a hug-versus-separation test. Wide separation from the averages supports the climactic-selloff case. Bars that hug the averages support a power trend, where the long stays withheld.

Gate the long and define invalidation

The long is withheld during the drop. A reversal trigger is an indecision, narrow-range, or bottoming-tail bar whose high must be taken out by a later up bar before a long is allowed. The archive allows the long only after that trigger bar forms and a following up bar trades through that bar's high.

The invalidation stop is a protective exit placed one price increment below the trigger bar low. In the worked example the initial protective stop sits one price increment below the indecision bar's low. A break of that low is treated as invalidation rather than a reason to add size.

If that stop is hit, the case study does not average down. It waits for a later setup at a lower price because another downward leg of similar size is considered likely.

Size the position and scale out

Position size in the worked example is set from a predefined cash risk divided by the entry-to-stop distance, then reduced to an even lot to leave room for slippage and costs.

Scale-out is staged position reduction at successive simple moving averages, with the remaining risk tightened after the first reduction. One documented path exits half the position at the eight-period simple moving average, moves the stop to breakeven, and exits the remainder at the 20-period simple moving average.

An alternative path takes the first reduction at the 20-period simple moving average and holds the balance toward a possible extension to the 200-period simple moving average.

Sampling interval and how often the pattern is used

The same bar-pattern rules are described as usable on most sampling intervals and especially on daily swing charts. One- and two-minute charts are said to produce many false triggers.

The case treats frequent weekly attempts at this countertrend pattern as a sign the trader is fading ordinary downtrends rather than isolating rare waterfall selloffs.
