How to read this page
- A flag is a stock a screen would have listed that day, under the same rules as the live screeners, applied to daily bars.
- Returns run from the close on the flag day to the close 5 and 20 trading days later, before costs and with dividends ignored.
- Win rate counts flags that moved the way the signal points: up after a breakout or episodic pivot, down after a breakdown.
- Each event is counted once, on the first day it shows, even if the screen listed it for several days.
The screens tracked
Donchian breakouts and breakdowns. A close above the highest high, or below the lowest low, of the previous 20 or 55 days: the turtle breakout rules, run on the same US stock and ETF list as the Donchian channel screener.
Episodic pivots. A gap up of 10% or more on at least 2.5 times normal volume, in a stock that had not already run, still holding above the gap day's low, with the Qullamaggie screener page's usual filters: price at least $3, at least $2 million a day traded, and an average daily range of at least 3%.
One flaw to know about: the past was scanned with today's symbol lists. Stocks delisted in the last year are missing, which flatters the history a little; merged and renamed stocks can be missing too.

Frequently asked questions
Why do recent flags show Pending?
The 5 or 20 trading days after the flag have not passed yet. The table fills them in as the days go by; flags are never removed or rewritten.
Do these numbers include costs or stops?
No. They are raw close-to-close returns with no commissions, slippage, stops or position sizing. Trading these setups lives on stops and sizing, so real results would differ, usually by a lot.
How often is this updated?
Once a day, after the US close. New flags are added and pending ones mature.
