ETH 15m Market Card Spread Data
Analyze ETH 15-minute Polymarket spread data with compact bid/ask views, liquidity summaries, and historical order book context.
ETH 15m market card spread data is a compact way to scan whether a market is tradable. The useful signals are best bid, best ask, spread width, available size near the top of book, and how those values change as expiry approaches.
Metrics to Show on a Market Card
- UP and DOWN best bid and best ask.
- Current spread and spread percentile for the market lifecycle.
- Top-of-book size and deeper available liquidity.
- Time to close and reference ETH price movement.
Why Spread Data Matters
A narrow midpoint can still hide poor execution if size is thin. For ETH 15m markets, spread data helps identify whether a signal is actionable, whether the market is stale, and whether a backtest should reject an entry because liquidity was not there.
