IPO Base

IPO Base tracks a recent listing's first consolidation through a full state machine — from post-debut pullback to defined base to breakout. The IPO base is the deliberate exception to standard base rules, and the build relaxes them the same way: a 10-bar minimum, a depth floor with no ceiling, and the first chart bar treated as the debut.

How to Trade the IPO Base?

• Defined base: buy point at the base high, invalidation at the base low — a watchlist flag, not an automatic entry.
• Volume-confirmed breakout: a triangle marks a close above the base high with volume 40% over average — the conventional buy point.
• Quiet breakout: a circle marks a clear without the pickup — thin floats push through on noise, so treat it as unconfirmed.
• Shakeout vs invalidation: a snap-back probe below the low prints a diamond — a supply test; one that holds prints a cross, and the base rebuilds from the same high.

Best on daily charts of recent listings; the dashboard reads like a watchlist row, from depth and tightening to volume dry-up and the lockup countdown.

IPO Base Settings

• Recent Listing Window (Days) (default 365): detection arms only while the listing is younger than this.
• Lockup Window (Days) (default 90 to 180): bounds of the shaded insider-lockup expiration window.
• Pullback Confirmation (Bars) (default 5) and Minimum Pullback Depth (%) (default 5): when a decline off the debut high starts a base.
• Minimum Base Length (Bars) (default 10): bars before the range earns a buy point.
• Shakeout Snapback (Bars) (default 2): closes below the base low tolerated before invalidation.
• Volume Average Length (default 50) and Volume Pickup Above Average (%) (default 40): the breakout-confirmation yardstick.
• The dashboard, level price tags, event markers, and lockup shading are display options.

Frequently Asked Questions

How does an IPO base compare to a flat base?

A flat base demands a prior uptrend, a multi-week minimum, and a tight depth ceiling; the IPO base waives all three because a new issue has no history to satisfy them. The price of flexibility is reliability — first bases fail often.

Why is the first chart bar treated as the debut?

The script has no listing calendar, so it anchors to the first bar of available history — accurate on daily charts of recent listings, where the pattern applies anyway. On long-history symbols the window passed long ago.

What does the lockup shading mean?

It marks the typical window when insider lockups expire — scheduled supply that can hit mid-pattern. A base can absorb that supply or break on the added float; the dashboard counts down and reports while the window is open.
