Analytics glossary

These are all the analytics available on the main Markets page, divided into standard metrics shown in the table by default and advanced metrics you can expand, sort, or filter on.

Standard Metrics

Odds

Current market price for the 'Yes' outcome, expressed as a percentage. Normal range: 5% - 95%. Extreme values (<5% or >95%) indicate high certainty outcomes.

Liquidity

Total available liquidity for trading. Deep: $50K+ (easy large trades). Moderate: $5K-$50K (some slippage). Shallow: <$5K (high slippage risk).

Volume

Total trading volume since market creation. High Activity: $100K+ (popular). Moderate: $10K-$100K (average). Low Activity: <$10K (niche/new).

24H Vol

Trading volume in the last 24 hours. Indicates recent market activity and interest.

Open Int.

Open Interest: total value of outstanding positions. High: $100K+ (many committed). Moderate: $10K-$100K (decent). Low: <$10K (limited).

Expires

The scheduled date and time when the market closes for trading, shown as a full calendar timestamp.

Competitive

Composite score (0-1) estimating how contested and efficiently priced the market is.

Advanced Metrics

Mid Price

Average of best bid and ask prices, representing fair market value. Mid Price = (Best Bid + Best Ask) / 2

Spread

Difference between best bid and ask prices. Tight (1-3%): liquid market. Wide (4-10%): moderate liquidity. Very Wide (>10%): illiquid market.

24h High

Highest 'Yes' price reached in the last 24 hours. Useful for identifying recent price peaks and resistance levels.

24h Low

Lowest 'Yes' price reached in the last 24 hours. Useful for identifying recent price floors and support levels.

Hi-Lo 24h

Hi-Low 24h Range: spread between the 24h high and low price as a percentage. Higher = more intraday price swings.

Hi 24h

Gap between the 24h high and the current price, as a percentage. How far the price has pulled back from today's peak.

Lo 24h

Gap between the current price and the 24h low, as a percentage. How far the price has bounced from today's trough.

Δ 1h %

Percentage price change over the last 1 hour. Stable: -5% to +5%. Volatile: -15% to +15%. Extreme: beyond -15% or +15%.

Δ 4h %

Percentage price change over the last 4 hours. Useful for identifying short-to-medium-term momentum shifts.

Δ 12h %

Percentage price change over the last 12 hours. Useful for identifying half-day trends.

Δ 24h %

Percentage price change over the last 24 hours. Key indicator of daily market sentiment shifts.

1h Vol

Trading volume in the last 1 hour. Useful for detecting sudden activity spikes.

4h Vol

Trading volume in the last 4 hours. Helps identify medium-term activity trends.

12h Vol

Trading volume in the last 12 hours. Shows half-day trading patterns.

Liq-Vol

Liquidity-to-Volume Ratio. Compares available liquidity with trading volume. Higher ratios indicate that the market is well-supported, leading to tighter spreads.

Turnover

Turnover Ratio = 24h Volume / Liquidity. High (>2): rapid capital recycling, potential volatility. Low (<0.5): stagnant capital.

Vol/OI Turn.

Volume/OI Turnover: how many times open interest turned over via trading in 24h (volume_24h ÷ OI). 1 = OI fully recycled once. Higher = more active relative to committed positions. Distinct from Turnover Ratio (which divides by liquidity, not OI).

I.P. Bias

Implied Probability Bias: how much 'Yes' price deviates from 50/50. Range −1 to 1. Positive: market favors 'Yes'. Negative: favors 'No'. Near 0: evenly split.

DS Ratio

Depth-Stress Ratio = Open Interest / Liquidity. >1: OI exceeds depth (high slippage risk). <1: book can absorb OI (lower risk).

Price Mom.

Price Momentum: rate of price change [−1, +∞). Can exceed 1 for near-zero-price markets. Positive: recent upward movement. Negative: recent downward movement. Near 0: stable.

Vol. Mom.

Volume Momentum: rate of volume change [−1, +∞). Values near −1 indicate near-zero recent volume; large positive values signal a surge in activity relative to the recent baseline.

Trend Str.

Trend Strength (R^2 value, 0-1). Strong (0.7-1): clear direction. Moderate (0.3-0.7): some direction. Weak (0-0.3): random/choppy.

Trend (m)

Trend Slope: rate of price change from linear regression. Positive: uptrend. Negative: downtrend.

Reversal

Reversal Rate [0-1]: frequency of price direction changes. Low (<0.3): trending market. High (>0.6): erratic/choppy price action. Near 0.5: random-walk behaviour.

Adj. Vol.

Adjusted Volatility score [0-1]: price uncertainty weighted by liquidity depth. Near 0: highly certain outcome with a deep order book. Near 1: close to 50/50 with thin liquidity.

Urgency

Resolution Urgency (0-1) - how close the market is to resolution, considering time, liquidity, and price certainty. High (0.7-1): resolution imminent.

Norm. Spread

Normalized Spread: bid-ask spread divided by mid-price. Values >1 occur for near-zero-probability markets where the spread is wider than the quoted odds. Range [0, +inf).

1h Vol %

1h Volume as a fraction of all-time volume. Near 1.0 means most of this market's lifetime volume traded in the last hour - a strong freshness signal for breaking markets.

4h Vol %

4h Volume as a fraction of all-time volume. Measures how concentrated recent 4-hour trading is relative to the market's full history.

12h Vol %

12h Volume as a fraction of all-time volume. Measures how concentrated recent 12-hour trading is relative to the market's full history.

Slippage

Expected Slippage: proxy execution cost of a large market order - min(1, (vol_1h / liquidity) * normalized_spread). Low (<0.05): cheap entry. High (>0.2): costly, illiquid. Range [0, 1].

Hover over any information icon for detailed explanations and the formulas used to calculate each metric.

Activity tab showing Recent Trades, Top Holders (Yes), Top Holders (No)

Clicking the Activity tab lets you see Recent Trades and the Top Holders of each YES/NO market.

The Recent Trades section breaks down the most recent trades in a specific market. In this view, you can see the wallet that placed the transaction, whether it was a buy or sell, the size of the order, whether they bought YES or NO, and the time the transaction took place.

Top Holders (Yes) and Top Holders (No) with Rank, Wallet, Shares, Unrealized PnL

The Top Holders view for both Yes and No sides shows the top holders of each position, including their wallet, a link to their Polymarket profile, total shares owned, and unrealized PnL, giving you a better idea of where money is flowing.

Use the trading toggle at the top of the window to switch to the Trading View. Here, you can monitor live market prices, view the order book, analyze market depth, and open or manage your positions.

To open a position, select your desired market (YES or NO), then choose whether to place a Market or Limit order. Enter the number of shares you wish to purchase or the dollar amount you want to spend. Click the Buy button at the bottom of the sidebar to submit your order. Once the transaction has been confirmed, the position will be added to your portfolio.
