Senzoukria heatmap stuck on “waiting for the first order book”

What you see

The heatmap area stays empty and its status line reads “{symbol} · waiting for the first order book”. When the backend knows more, the line shows the book state instead: BOOK SYNCING, BOOK RESYNC, BOOK RECONNECT n/m, or BOOK STOPPED.

Why it happens

• Rithmic: the market is closed or in its daily break, so no book is published; or the depth subscription was refused, which is shown as a separate refusal notice.
• NinjaTrader or Quantower bridge: the bridge is not live yet, or the platform chart sends no depth.
• Databento CME: the key lacks the live licence for the order book; the notice then carries Databento’s wording.
• Crypto (Binance, Bybit): the exchange accepted the subscription but no snapshot arrived; after 15 seconds a “No market depth received” notice appears with a Retry.
• dxFeed: no depth is requested on that rail, so the heatmap stays empty by design.
• In 0.45.0, the heatmap could also fail to start in the installed app; that case shows “could not start” and is fixed in 0.46.0.

How to fix it

• Check the market hours of the contract; on CME, the heatmap fills when quotes resume.
• Check the Chart source panel of the heatmap settings and pick a source that carries depth.
• For a Rithmic contract, make sure the connection is live and the contract is the current front month.
• For a bridge, confirm the footprint shows LIVE for the same instrument first.
• For crypto, use Retry on the notice, or switch pair and back.

What it is not

• Not an empty market: a map without data and a map without liquidity look the same, which is why the line says “waiting”.
• Not a display setting: intensity or contrast cannot create a book that has not arrived.

When to contact support

If the steps above do not change anything, send the case from Menu → Report a problem, or ask on the Senzoukria Discord. Give the source, the contract, the time and the exact status line (or book state) shown.
