The share line shows the midpoint of the UP token's order book — the average of the best bid and best ask. It is green above $0.50 (UP bias) and red below $0.50 (DOWN bias).
The price strip shows Bid (best buy offer), Ask (best sell offer), Spread (gap between them), and Last (most recent actual trade). We use the midpoint for the chart because individual trades can spike when a large order sweeps thin liquidity.
Why do trades spike to $0.01 or $0.99? Polymarket uses a limit order book. A large market order fills at progressively worse prices. A buy might fill 100 shares at $0.15, then 50 at $0.30, then 10 at $0.95. That $0.95 fill is just one piece of the sweep — it doesn't mean the market price is $0.95. The midpoint stays stable.
Why Only One Share Price Line?
For binary options, UP price + DOWN price ≈ $1.00. They are mirror images. If UP is $0.15, DOWN is ~$0.85. Showing both creates clutter without adding information. The single green line tells the full story.
BTC Lines And Strike Label
Settlement (cyan) — Chainlink BTC/USD reference via Polymarket RTDS. This is the settlement reference we use for strike and calculator logic. It normally updates around once per second and should reconnect automatically if the socket goes stale.
Strike (white dashed) — The BTC price when the market was created. If BTC is above this at expiry → UP wins. Below → DOWN wins.
Strike label — The right-side label now shows strike, current dollar delta, percent delta, and an ATR-normalized edge score. The score maps 1.68x 5m ATR to 100%.
Market Focus Panel
The top-right focus panel is back to being a market summary, not a duplicate paper summary. It now shows the live Polymarket share price, Polymarket settlement BTC price, strike, dollar delta, percent delta, a combined flow read, and time to expiry in seconds.
Orderbook Pressure (Chart & Focus Panel)
Shown as a compact score and label in the focus panel. Ranges from -100 to +100. Positive values are buy pressure, negative values are sell pressure, and near-zero values are balanced. On the chart it is drawn as a thin dotted line so it stays visible without overwhelming the share line.
Target Distance
Shows the gap between the current settlement reference (Chainlink BTC/USD) and the strike. Green ▲ means BTC is above strike (UP winning). Red ▼ means below (DOWN winning). Uses the Chainlink reference because that's what determines the calculator's market context.
Edge Signal
Compares price feeds to identify potential trading opportunities:
Fut-Stl — Futures vs Settlement spread. When futures diverge from the settlement price, this indicates potential directional momentum.
Spot-Stl — Spot vs Settlement spread. Similar signal, slightly slower than futures.
Fut-Spot — Futures vs Spot spread. Large positive = aggressive buying in futures = bullish momentum.
Stl age — Seconds since the Chainlink settlement source itself last changed. With RTDS this should usually stay very low; if it climbs for too long, the socket is stale and needs recovery.
Trading insight: The settlement reference should behave like a live stream, not a slow staircase. A few repeated values are normal, but the age badge should keep refreshing and the reconnect watchdog should recover the feed if updates stall.
Market Depth Bars
Shows bid (buy) vs ask (sell) volume at different depth levels:
T1 = Top 1 price level (tightest, most relevant)
T3 / T5 / T10 = Top 3 / 5 / 10 levels
All = Entire visible orderbook
Green bar = bid volume (buyers). Red bar = ask volume (sellers). The score shows the imbalance percentage.
ATR And Range Read
The chart no longer draws the normal-range bands. Instead the top-right summary shows a compact range status and ATR snapshot:
In Range / Above / Below — where the share price sits versus its recent normal range
ATR 5m / 15m / 1D — the current BTC volatility context from Binance klines
Paper Trading Lab
The right-hand paper section now shows a click-to-expand strategy list instead of large static cards. The rows are pulled from the best finalized backtest candidates across all completed days, with a broader 16-strategy deployment and better long/short balance.
PnL% is the most important live paper number and is colored green or red first.
Win is closed-trade accuracy in the live paper session.
Fill is how often a signal actually became a trade after the one-cent through-price rule.
Session shows how long the current paper file has been running since the latest reset.
Open the row to inspect live status, backtest source stats, and the recent closed trades.
The live paper engine still uses fixed 1% sizing from the shared bankroll, only counts a fill when the market moves through the quoted limit, and now archives each session to file when you reset so earlier paper runs remain available for later analysis.
