SPX is an index measuring a broad group of large U.S. stocks, not a share you can buy. An option is a contract whose value depends partly on another market, called its underlying. The strike is the specified exercise level. At expiration, a call pays off if its underlying finishes above the strike; a put pays off if it finishes below. Expiration is when the contract ends, and settlement determines and delivers what is owed under its terms.
A level is a reference price, and a zone is the small area around it where you observe the reaction. Call Wall marks heavy call positioning and Put Wall marks heavy put positioning. Positioning means the contracts participants are estimated to hold. Magnet marks a strike around which price may spend time. Support is an area where a decline may slow; resistance is an area where an advance may slow.
Dealers buy and sell contracts and use other positions, called hedges, to offset risk. Gamma measures how quickly an option's sensitivity to its underlying changes as that market moves. Estimated dealer gamma exposure combines that sensitivity with estimated positions. A dampening backdrop means hedge adjustments could oppose price moves; an amplifying backdrop means they could reinforce moves in either direction. Gamma Flip is the daily reference used to frame that distinction. Vol Pivot is a separate reference whose loss can accompany wider price swings.
VWAP means volume-weighted average price: prices with more supplied volume have more influence on the average. This viewer calculates it from chart-bar midpoints rather than individual trades in the index. A bar, also called a candle, summarizes the opening, highest, lowest, and closing prices during one interval. Standard deviation measures the spread of those midpoints around the average. The inner boundaries sit one standard deviation above and below VWAP. Price between them is balance; above is discovery up; below is discovery down. Outer bands mark larger distances from the average.
Flow here means estimated buying or selling pressure from dealers adjusting hedges. Read its recent direction alongside price. Scope identifies the contracts or reference set a level covers: all-expiration combines expiry dates, while 0D means options expiring today. A daily reference belongs to the daily level set and is not automatically a same-day option level.
A rejection tests a zone and moves away; a reclaim moves back across it and holds. Acceptance means price stays beyond a zone instead of quickly returning. A held retest revisits the area, stays on the intended side, and starts moving away again. A pullback temporarily moves against the recent direction; continuation resumes that direction, while rotation moves back through a range or toward an average. Invalidation is the behavior that cancels the idea.
