O'Neil Base Analysis

O'Neil Base Analysis runs the base life cycle of O'Neil base analysis shape-agnostically. A candidate anchors at a high and matures once it passes the prior-uptrend, length and depth checks, waiting with a dotted live pivot line. A closing breakout draws the base box, grades quality, stamps the stage label and opens the failure watch, buy zone and stop line drawn.

How to Trade the O'Neil Base Analysis?

• Pivot buy vs weak-volume breakout: a close through the pivot on volume at least the surge above average is confirmed; without it, alerted as unconfirmed.
• Buy zone discipline: entries belong in the narrow zone above the pivot: beyond it prints Extended; a heavy-volume close back inside the base is the early warning.
• Base failure: a drop to the stop below the buy point is an automatic sale under the fixed loss rule — no debate.
• Base count: a pivot forming sufficiently above the prior one advances the stage; late stages turn labels cautionary, and a decline below the prior base's low resets the count.

O'Neil Base Analysis Settings

• Prior Uptrend Minimum % (default 30) and Uptrend Lookback (bars) (default 40): the prerequisite advance.
• Minimum Base Length (bars) (default 5) and Maximum Base Depth % (default 33): what counts as a base rather than a correction.
• Pivot Margin Above Resistance % (default 0.1), Buy Zone Above Pivot % (default 5) and Base-Failure Stop % (default 7): entry and loss geometry.
• Volume Average Length (default 10) and Breakout Volume Surge % (default 40): breakout confirmation; Breakout Resolution Gain % (default 20) ends the failure watch.
• Stage Increment Threshold % (default 20) and Late-Stage Threshold (default 3): base counting.
• Tight Closes: Max Average Change % (default 4) and Volume Dry-Up Window (bars) (default 5): quality grading, plus display toggles.

Frequently Asked Questions

How does this differ from a cup-with-handle detector?

A Cup With Handle Base detector targets one named shape. This build validates any consolidation against the shared prerequisites and runs what every shape shares — pivot, volume confirmation, counting, the failure rule.

What does the Q score in the stage labels mean?

Three checks over the base body: tight bar-to-bar closes, recent volume below its average (the dry-up), and up-day volume exceeding down-day volume — the quiet-accumulation signature of a sound base.

Which timeframe should I use?

Weekly charts — the defaults are sized for them, the shortest standard bases running about 5 weeks. On daily charts raise the Volume Average Length to 50 and scale the lengths to match.
