# Support/Resistance & Levels > Pivot families, the Fibonacci suite, supply & demand zones, and anchored references. Levels are the horizontal prices traders plan around: where a market has stalled before, where a formula projects the next reference point, or where resting orders are likely to sit. Some are read directly from price history, like support and resistance zones, prior highs and lows, and the bases that launch strong moves. Others are calculated, from classic pivot formulas to Fibonacci ratios applied to a chosen swing. This family collects both kinds along with the craft around them: how raw touches get merged into zones, how a level's freshness is judged after repeated tests, what separates a real break from a fake-out, and where anchored references such as period opens, VWAP, and option strike walls fit in. Every page connects the concept to the Library indicators that implement it. ## Pivot families Formula-based reference levels projected from the prior period's prices, from the classic floor-trader calculation to Camarilla, Woodie, Fibonacci variants, and the Central Pivot Range. - [Pivot Points](https://www.luxalgo.com/library/concept/pivot-points.md): 2 implementations - [Floor Pivots](https://www.luxalgo.com/library/concept/floor-pivots.md): 1 implementations - [Camarilla](https://www.luxalgo.com/library/concept/camarilla.md): 1 implementations - [Woodie Pivots](https://www.luxalgo.com/library/concept/woodie-pivots.md): 1 implementations - [DeMark Pivots](https://www.luxalgo.com/library/concept/demark-pivots.md): 1 implementations - [Fibonacci Pivots](https://www.luxalgo.com/library/concept/fibonacci-pivots.md): 1 implementations - [Central Pivot Range](https://www.luxalgo.com/library/concept/central-pivot-range.md): 1 implementations ## Fibonacci suite Ratio tools measured off a chosen swing: retracements and the golden pocket, extensions and projections for targets, plus time, geometry, and confluence applications. - [Fib Retracement](https://www.luxalgo.com/library/concept/fib-retracement.md): 8 implementations - [Fib Extension](https://www.luxalgo.com/library/concept/fib-extension.md): 3 implementations - [Fib Geometry Tools](https://www.luxalgo.com/library/concept/fib-geometry-tools.md): 2 implementations - [Fib Projection](https://www.luxalgo.com/library/concept/fib-projection.md): 1 implementations - [Fib Time Tools](https://www.luxalgo.com/library/concept/fib-time-tools.md): 1 implementations - [Fib Clusters](https://www.luxalgo.com/library/concept/fib-clusters.md): 1 implementations - [Golden Pocket](https://www.luxalgo.com/library/concept/golden-pocket.md): 1 implementations ## Horizontal S/R The core support and resistance craft: how touches are detected, merged, and scored into zones, how broken levels swap roles, how freshness fades as tests accumulate, and why round numbers matter. - [S/R Zone](https://www.luxalgo.com/library/concept/s-r-zone.md): 19 implementations - [Level Interaction Rules](https://www.luxalgo.com/library/concept/level-interaction-rules.md): 6 implementations - [Level Clustering Algorithms](https://www.luxalgo.com/library/concept/level-clustering-algorithms.md): 6 implementations - [Support Level](https://www.luxalgo.com/library/concept/support-level.md): 1 implementations - [Resistance Level](https://www.luxalgo.com/library/concept/resistance-level.md): 1 implementations - [Level Freshness & Decay](https://www.luxalgo.com/library/concept/level-freshness-and-decay.md): 1 implementations - [Round Numbers](https://www.luxalgo.com/library/concept/round-numbers.md): 1 implementations - [Role Reversal](https://www.luxalgo.com/library/concept/role-reversal.md): build pending ## Supply & demand methodology Zone-based analysis that marks the origins of strong moves as supply or demand, then grades each area for quality, freshness, and position on the higher-timeframe curve. - [Supply & Demand Zones](https://www.luxalgo.com/library/concept/supply-and-demand-zones.md): 6 implementations - [Zone Scoring & Refinement](https://www.luxalgo.com/library/concept/zone-scoring-and-refinement.md): 1 implementations - [Curve Position](https://www.luxalgo.com/library/concept/curve-position.md): 1 implementations ## Anchored/reference levels Reference prices anchored to something specific: prior highs and lows, period opens, all-time and 52-week extremes, overnight and extended-hours trade, VWAP from a chosen anchor, and option strikes with heavy open interest. - [Prior Period Levels](https://www.luxalgo.com/library/concept/prior-period-levels.md): 3 implementations - [All-time & 52-week Extremes](https://www.luxalgo.com/library/concept/all-time-and-52-week-extremes.md): 3 implementations - [Monday Range](https://www.luxalgo.com/library/concept/monday-range.md): 1 implementations - [Overnight & ETH Levels](https://www.luxalgo.com/library/concept/overnight-and-eth-levels.md): 1 implementations - [Anchored VWAP As Level](https://www.luxalgo.com/library/concept/anchored-vwap-as-level.md): 1 implementations - [Period Opens](https://www.luxalgo.com/library/concept/period-opens.md): build pending - [Naked POC As Level](https://www.luxalgo.com/library/concept/naked-poc-as-level.md): build pending - [Max Pain Level](https://www.luxalgo.com/library/concept/max-pain-level.md): build pending - [Option Strike Walls](https://www.luxalgo.com/library/concept/option-strike-walls.md): build pending ## Exotic level systems Rule-based price grids from Murrey Math and Gann's Square of 9;
