Turning flat bases into breakout system rules

A chart condition, not an order

A flat base is a stretch of narrow, low-participation price action that precedes a breakout attempt. In the archive workflow it is read as low interest and tight trading, often a visually narrow or only gently rising stretch with quiet volume.

A flat-base breakout is defined as a session whose close exceeds the highest high of the prior 60 days after that quiet stretch. The breakout session is read as a sudden one-day imbalance shown in both price and volume, preferably with a sharp volume increase.

The first-pass scan

On the latest close, the candidate scan requires a close above the prior 60-day peak close, a close below 50, a close above that day's open and at least 2, a 63-day exponential average of volume at or below 500,000 as of the prior session, a higher close than the prior session, and volume at least five times the 60-day minimum and three times the prior day's volume.

The candidate profile

After the scan, remaining names are reduced by a candidate profile. That second pass prefers a small share count, low typical volume, a strong industry-group relative-strength grade, substantial insider ownership, a large breakout-day volume multiple, little or no accompanying news, a quiet prior tape, a confirmed bullish market, no overhead supply from the prior 12 months, and listing on one specified electronic market.

When two candidates remain, the procedure prefers the stronger industry group, then the higher relative-strength reading, then the smaller share count.

Confirmation, fill, and abstention

The entry rule does not buy the breakout print. It places a confirmation buy-stop about 0.25 above that day's high for the next session so a failure to continue is not filled.

Immediately after a fill, a protective sell-stop is placed 7 percent below the execution price.

Abstention means leaving a scanned name untraded when the next-session stop is not elected or the candidate profile is not met.

The dual-average exit

While the position is open, the planned exit is a next-session market sale after a 3-day closing exponential average turns down through a 6-day closing exponential average.

In the reviewed cases, most of those average-cross exits arrived 14 to 35 days after the breakout, so the designed holding period is several weeks. Three illustrated names show a high-volume lift from a multi-week base followed by a later 3-day versus 6-day average-cross exit.

Editorial: one written procedure

Editorial: TradersWeek treats the quiet base as a chart condition that becomes a breakout system only after confirmation, abstention, and the dual-average exit are written in advance. A failed next-session stop is a designed outcome of the same procedure as taking the trade, so entry, sitting out, and exit can be tested together.
