Explore Polymarket OHLCV charts with recorded volume, side-by-side outcomes and settlement references. Understand what each candle actually measures.
Omens · Updated
A line chart follows a price through time. An OHLCV candle also shows where a period opened and closed, its highest and lowest recorded trade prices, and how many shares traded. Omens brings that view to Polymarket crypto and esports outcomes in a browser-based analysis terminal.
What OHLCV means for a prediction market
Each candle describes one outcome token over one interval. The interval could be a second or a minute; it is different from a market round, which can last five minutes or much longer.
| Field | What it measures |
|---|---|
| Open | First recorded execution price in the interval |
| High / Low | Highest and lowest recorded execution prices |
| Close | Last recorded execution price in the interval |
| Volume | Shares in the recorded executions, not a count of quote updates |
A trade chart and a quoted price answer different questions
Omens builds outcome candles from available recorded and recovered executions. A last-trade price can differ from the quote currently displayed on Polymarket: Polymarket describes its displayed price as the order-book midpoint, with a last-trade fallback when the spread is wide. Neither a midpoint nor an old execution guarantees the price of a new order.
Polymarket’s price-history endpoint returns time-and-price observations. That series alone cannot recover every execution, its size, or the true traded volume within a candle. Recorded execution volume is a separate measurement.
Compare outcomes with the underlying reference
Open a market from the directory and compare its Up/Down or Yes/No charts. Candle prices are displayed in cents. Inspect recorded volume below the price chart and use the trades list to examine individual executions.
For supported crypto rounds, the related reference chart provides context for the market’s price to beat. Outcome-token prices, a crypto asset’s spot price and its settlement reference measure different things. The source and settlement rules for that market determine which reference matters.
Read quiet periods and missing history carefully
A display-only flat candle can carry a prior price forward with zero recorded volume. It is not another trade. A missing collection interval does not establish that the source had no trading. Available history varies by token, time range and recovery source.
Changing the interval aggregates the available observations; it cannot manufacture missing executions. Check the market’s history and the time range before comparing totals or drawing conclusions from a sparse chart.
Move from the chart to historical statistics
The terminal shows round-level traded value and average traded price. The Analytics workspace lets you inspect past rounds and price-conditioned settlement frequencies, with eligible sample counts. These are descriptions of observed history, not forecasts.
