The 2-1-2 Setup
The 2-1-2 is the sequence most traders learn first: a directional bar (2), an inside bar (1), and then the break of that inside bar. The inside bar is the market catching its breath; the break tells you whether the pause was a rest stop or a turning point.
Reversal or continuation — the same bar decides
After a 2d, an inside bar, and a break of the inside bar's HIGH: that is the 2-1-2 bullish reversal — the down move paused and got rejected. Break the inside bar's LOW instead and the same three candles are a bearish continuation. One setup bar, two opposite trades, decided only by which trigger goes first. That is why naming the side matters: the same sequence is a reversal one way and a continuation the other.
The trade, the Strat way
Entry is the break of the inside bar's high or low. Our engine confirms intraday breaks on a close through the level (wick pokes don't fire); daily and above trigger at the tag. The stop belongs at the opposite side of the setup bar (many traders, and our alert engine, use the setup bar's 50% line: if price retraces through the middle of the bar it broke from, the 2 has failed). The first target is the prior structural level — the last pivot in the trade's direction; the measured move (one setup-bar range beyond the break) is the standard extension.
What failure looks like
A 2-1-2 that breaks out and then trades back through the setup bar's midpoint is a failed 2 — and failed 2s are themselves one of the most powerful signals in the method, because everyone who took the breakout is now trapped. If you trade 2-1-2s, you must know the failed 2, if only to recognize when you have become the fuel.

FAQ
What is the difference between 2-1-2 reversal and continuation?
The same three-candle shape. If the third candle breaks the inside bar against the first candle's direction, it is a reversal; with it, a continuation.
Where does the stop go on a 2-1-2?
Classically at the opposite extreme of the inside bar; the stricter convention is the setup bar's 50% line — a retrace through the middle of the bar means the break has already failed.
Which timeframes do 2-1-2s work on?
The pattern occurs on all of them. Higher-timeframe versions (daily and up) carry more participation, and versions aligned with full timeframe continuity are the classic A-grade context.
