How GALT put/call volume history Data Feeds Strategy Selection
Strategy selection on Galectin Therapeutics Inc. options does not derive from any single metric in isolation. The put/call volume history view above sits inside a broader read: ATM IV currently sits at 122.4% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the put/call volume history data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.
How to read the GALT volume data
The volume time-series above tracks Galectin Therapeutics Inc. options trading activity day by day. Volume is a flow measure - contracts traded per day across all strikes and expirations - so spikes flag activity, not positioning. Current put/call ratio is 1.73, put-heavy - protective or bearish positioning dominates. Total call OI of 20.3K versus put OI of 2.4K gives a put/call OI ratio of 0.12 - structurally a slower-moving signal than the volume-based ratio.
GALT flow vs positioning
Volume tells you what flows happened today; OI tells you what positions accumulated. Both can move in opposite directions: rising volume with falling OI means contracts are being closed (covering); rising volume with rising OI means new positions are being opened. The combination matters more than either alone for reading sentiment. Combined with the current positive dealer-gamma regime, large OI clusters tend to act as price magnets through expiration cycles.
Using GALT OI/volume data alongside other surfaces
Per-strike OI is the input to dealer-gamma calculations: strikes with elevated call OI generate gamma walls that dealers must hedge into as spot approaches them. The gamma-exposure page combines this distribution with the dealers' assumed-long-gamma assumption to project hedge flow. Volume cross-checks recent positioning shifts in the chain that haven't yet shown up in cumulative OI. Pair both with the term-structure view on the volatility page to determine whether the activity is concentrated in near-dated event hedging or longer-dated structural positioning. Front-month expiration for GALT sits at 20 days, so near-dated volume currently dominates the flow reading.

Frequently asked GALT put/call volume history questions
- How much GALT options volume traded today?
- As of May 29, 2026, Galectin Therapeutics Inc. (GALT) traded 153 total options contracts, split as 56 calls and 97 puts. Volume measures today's flow only; standing inventory is captured by open interest, which reconciles after the close.
- What is the GALT put/call volume ratio?
- As of May 29, 2026, the put/call volume ratio is 1.73. Equity-only PCR has three competing interpretations - sentiment-contrarian (extremes signal turning points), hedging-flow (high PCR can be portfolio insurance demand rather than bearish bets), and informed-flow (the volume signal carries short-horizon predictive content per Pan and Poteshman 2006). Resolving which frame applies requires context on whether the flow is opening or closing and which strikes carry the activity.
- Is GALT options volume elevated?
- Elevated flow relative to the GALT recent average is one of the strongest signals of institutional positioning, pending news, earnings expectations, or hedging activity. The most informative reads combine elevated volume with directional structure (single-leg or vertical), aggressive execution (at the ask or sweep), and an upcoming catalyst on the calendar.
