# Classic Bar Setups Classic Bar Setups is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Classic Bar Setups detects Larry Williams' Oops, Joe Ross' gimmee bar, and 80-20 session reversals as complete rules: each label places a working entry stop, draws its protective stop, and cancels on a time-stop. An ADX sideways filter gates gimmee bars, and fills print as triangles. Mechanical bar-pattern trading for session-based markets. - Indicator in the LuxAlgo Library, by LuxAlgo, published May 24, 2026. - Access: free. - Concepts: [Classic Bar Setups](https://www.luxalgo.com/library/concept/classic-bar-setups/) (primary) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=de50pti0pnn5lpahvcllvshk - Page: https://www.luxalgo.com/library/indicator/classic-bar-setups/ **Classic Bar Setups** trades three named patterns from the systems-trading canon as complete rules rather than shapes: Larry Williams' Oops, Joe Ross' gimmee bar, and the 80-20 session reversal. Each detection places a working entry stop, draws its protective stop, and cancels itself on a time-stop, making it the definitive clean build of the [classic bar setups](https://www.luxalgo.com/library/concept/classic-bar-setups/) catalog: every label corresponds to a working order. ## How to Trade the Classic Bar Setups? - **Oops**: the session gaps open beyond the prior bar's extreme; the entry stop waits back at that extreme and fills only if price trades back through it, live during the gap session itself. - **Gimmee Bar**: in a non-trending market, a bar pressing into a Bollinger band edge closes against its own direction; entry is a stop one tick beyond the bar's far side. - **80-20**: a full-range session opens near one extreme and closes near the other; the next session waits for a push back through the far extreme, arming on first touch beyond it. - **Lines and triangles**: dashed entry and dotted stop levels draw for each order's life; a triangle marks the fill. ## Classic Bar Setups Settings - **Oops** (default on) with **Minimum Gap %** (default 0): the smallest qualifying gap; 0 accepts any open beyond the prior extreme. - **Gimmee Bar** (default on) with **Bollinger Length** (default 20) and **Mult** (default 2): the range edges the bar must press into. - **Sideways Market Filter** (default on) with **ADX Length** (default 14) and **Threshold** (default 20): gimmee bars only count while the market is range-bound. - **80-20** (default on) with **Open/Close Zone %** (default 20): how near the extremes the open and close must sit; the classic rule uses 10-20%. - **Trigger Window (Bars)** (default 1): bars an entry stop stays working before it cancels. - Style: **Show Entry Levels**, **Show Protective Stops**, and **Show Trigger Markers** (default on), **Show Bollinger Channel** (default off). ## Frequently Asked Questions ### How is this different from Candlestick Patterns? [The candlestick detector](https://www.luxalgo.com/library/indicator/candlestick-patterns/) names shapes and leaves the trade to you. These setups ship as full rules: the bar geometry merely triggers a defined stop order, hence order levels on the chart, not just labels. ### Why did a setup label print but never trigger? The entry stop never filled inside the trigger window, so the time-stop cancelled it. That is the design: a trap price never springs is not a trade. ### What do these setups have in common? Each fades a failed first move: Oops catches traders trapped by an opening gap, the gimmee bar exploits a rejected press at a range edge, and 80-20 plays for reversion after a one-way session. ## Related indicators - [Candle 2 Closure](https://www.luxalgo.com/library/indicator/candle-2-closure/) (Two-bar Reversal): markdown at https://www.luxalgo.com/library/indicator/candle-2-closure.md - [Long Wick Detector](https://www.luxalgo.com/library/indicator/long-wick-detector/) (Pin Bar): markdown at https://www.luxalgo.com/library/indicator/long-wick-detector.md - [The Strat](https://www.luxalgo.com/library/indicator/the-strat/) (Inside Bar): markdown at https://www.luxalgo.com/library/indicator/the-strat.md - [N Bar Reversal Detector](https://www.luxalgo.com/library/indicator/n-bar-reversal-detector/) (Three-bar Reversal): markdown at https://www.luxalgo.com/library/indicator/n-bar-reversal-detector.md - [Wide-range Bar](https://www.luxalgo.com/library/indicator/wide-range-bar/) (Chart & Candlestick Patterns): markdown at https://www.luxalgo.com/library/indicator/wide-range-bar.md - [Engulfing Bar](https://www.luxalgo.com/library/indicator/engulfing-bar/) (Chart & Candlestick Patterns): markdown at https://www.luxalgo.com/library/indicator/engulfing-bar.md - [CBC Flip with Targets and Filters](https://www.luxalgo.com/library/indicator/cbc-flip-with-targets-and-filters/) (Two-bar Reversal): markdown at https://www.luxalgo.com/library/indicator/cbc-flip-with-targets-and-filters.md - [Exhaustion Bar](https://www.luxalgo.com/library/indicator/exhaustion-bar/) (Chart & Candlestick Patterns): markdown at https://www.luxalgo.com/library/indicator/exhaustion-bar.md --- Source: https://www.luxalgo.com/library/indicator/classic-bar-setups/ (LuxAlgo Library).
