Wide-range breakout, trailing stops, and pyramiding

Four sequential rules

A wide-range breakout procedure can be written as four sequential rules: require at least a 20 percent high-low range on a 15-day chart in an uptrend, enter a half-dollar above the current high, place a two-dollar initial stop, and add to winners every two dollars.

Those four steps are a breakout system: a complete entry, exit, and abstention procedure that waits for price to leave a defined range and then applies the same testable rules through the holding period.

Why range size comes first

The same case study treats the size of the trading range as more important than the visual chart pattern, because a narrow range produces more false breakouts than a wide one.

The first rule is a wide-range filter: a pre-entry screen that requires a large high-to-low range on a short lookback so the breakout is not taken from a tight, false-breakout-prone band. The stated screen is a 20 percent high-low range on a 15-day chart, and only in an uptrend.

Initial and trailing stops

The entry is a half-dollar above the current high, and a two-dollar initial stop is written as part of the same procedure.

Trade management in the case study pairs the breakout with tight initial and trailing stops. A trailing stop is a risk bound that starts as a fixed initial stop and then follows the position so a loss or exposure decision stays limited before and after entry. An early pullback or consolidation after entry is treated as a reason to exit sooner rather than later.

Adding only after a stated move

The fourth rule adds to winners every two dollars. That is pyramiding: a rule for adding to a winning position only after price has already moved a stated increment in the trade's favor.

A stiffness reading as another breakout screen

A related stiffness-based breakout implementation buys when a three-bar smoothed stiffness reading crosses above a buy threshold of 90 and a second-data-series market trend average is non-declining. It then sells on a cross under a sell threshold of 50 or after 84 bars.

Stiffness itself is computed by counting closes above a moving average that has been lowered by two-tenths of its own standard deviation, then scaling that count by the moving-average length over the stiffness lookback.

Default stiffness parameters used across the supplied implementations are a 100-bar moving average, a 60-bar stiffness count, a 90 buy threshold, and three-bar exponential smoothing of the indicator.

Time without progress as an exit

A stiffness system test pairs the same entry and exit thresholds with a 21-day inactivity stop on long positions that requires a 100 percent minimum change. An inactivity stop is a time-based exit that closes a position if price has not made a required change within a stated number of bars, which makes time without progress an explicit exit rule.
