Classic Bar Setups

What are Classic Bar Setups?

Classic bar setups are the named one- and two-bar entries of late twentieth-century trading literature: patterns like Larry Williams' Oops, Joe Ross' gimmee bar, and 80-20 style reversal bars. What separates them from generic candlestick names is that each ships as a complete rule: a precise bar geometry, an entry level, a direction, and usually a stop, rather than a shape left to interpretation.

Most of them encode the same underlying event, a trapped initial move. Oops fades an opening gap beyond the prior day's extreme once price trades back through it; the gimmee bar fades a push into the edge of a trading range when the pressing bar closes against its own direction; 80-20 bars (open near one extreme of the day, close near the other) flag potential next-session reversion. Each is a bar-scale false breakout with the trigger written down.

How traders use it

• As mechanical triggers at chosen locations: because each setup defines its own entry and stop, traders bolt them onto a location thesis (a level, a session open, a range edge) as the execution rule.
• As backtest material: the definitions are objective enough to code, which is also the honest warning; results vary with market regime, so they need testing on the instruments and eras actually traded rather than trust on reputation.
• As a vocabulary for trap logic: even traders who never take the setups verbatim use them as clean descriptions of failed opens, failed range pushes, and failed breakouts at bar scale.
