What’s new

Every change that reached tapeworm.app, newest first. Tapeworm is in open beta and ships often: current version v0.6.2, updated October 24, 2026.

v0.6.2 · October 24, 2026

Clearer status, steadier Net Liquidity

  • Net Liquidity stays up when the St. Louis Fed's data site (FRED) is down: the card now falls back to the Federal Reserve Board's own copy of the same Fed balance-sheet number.
  • One outside source being down no longer looks like an outage. Only our own market feed turns the header chip to DOWN; a single source (like the Fed balance sheet) shows as an amber "1 data source down" banner, with the chip still LIVE.
  • Fixed: the Tape flagged the feed's normal weekday 1:05–3:00 PM PT pause (around the futures daily break) as "Data feed down".
  • Dealer gamma regime now follows price against the flip: above the flip reads positive, below it negative. The two could disagree when price sat right next to the flip.
  • Steadier data on rough mornings: if our options-data connection stalls, prices and bands now still update on time; only the walls skip that 5-minute read.
  • Fixed: when one of our options-data reads failed, the dealer gamma card, walls and flip went blank until the next read. They now keep the last good reading.
  • The Tape header now shows how fresh the numbers are and when the next read is due ("AS OF … · 2 min ago · next ~10:27 ET"), turning amber if a read is late. Values that change on a refresh, like the regime or a wall, briefly light up.
  • The Tape's cards now refresh in step with our data feed, so a new reading (like a regime change) shows within a minute or two instead of up to ten.
v0.6.1 · October 21, 2026

Know when a data source is down

  • If our market-data feed falls behind, or an outside source like the Fed balance sheet, Treasury or the NY Fed stops answering, the Tape now says so at the top: "Data feed down (under investigation)", with what's affected. The header chip reads DOWN until it's back.
  • Planned maintenance and announcements now appear as a banner on every page, with the time window. You can dismiss them; outage notices stay until they're over.
  • Fixed: when the Fed's data site was down for maintenance, Net Liquidity showed a blank "no data". It now says "Fed Balance Sheet is down for maintenance".
v0.6.0 · October 19, 2026

See where price sits inside the priced move

  • New on the Tape: the EM band gauge. A ring that shows where price sits inside the move the options market priced: 50% is the anchor, 0 and 100% are the edges, past them is beyond the priced move.
  • Overnight it uses the 5 PM PT band on the next expiry, with the thinner 3 PM reopen read alongside and the gap from the prior close shown separately. In the session it switches to the frozen session band; over the weekend it shows Friday's band, grayed out and labelled as Friday's.
  • The ring keeps a faint mark at the session high, and flags a tag of the top or bottom edge that reverted.
  • Fixed: a missing options read at 6:45 AM PT could leave a market with no session band all day. The next anchor with a read now stands in, marked late.
  • Fixed: on Sunday evening the Tape could show a morning session band stamped at the 3 PM reopen.
  • The liquidity card adds the 4-week TGA flow and warns when a big one-day Treasury cash move sits at the edge of the 20-day window.
  • The economic calendar is refreshed through December 31.
v0.5.1 · October 13, 2026

Set-up lights on NQ and the Russell

  • The set-up lights now run on NQ and RTY too, not just ES. Their track records were measured on ES, and the card says so.
  • Beta Pro: import 20 or more trades and unlock Pro with one click. The button stays grayed out until you reach 20.
v0.5.0 · October 11, 2026

See any day up close

  • Blackbox → By condition has a day picker: choose a day you traded to see that day's market conditions, a chart with the walls, EM band and 240m line, and your entries and exits on it.
  • Each trade gets one line saying what was true when you entered: distance from the 240m, where price sat in the EM band, dealer gamma, walls, EM/ATR. Unusual parts are highlighted.
  • Ask Moneyness "why did I lose on this day?" or "how do I do in negative gamma?" and she answers from your own trades.
  • Market conditions are now back-filled from CME history for ES/MES and NQ/MNQ trades since June 2025, marked "back-filled"; walls (and NQ's gamma regime) are approximate on those.
  • Release notes live here and in the app (What's new, top right).
v0.4.1 · October 9, 2026

Know when your records are behind

  • The Tape's Trader card has a new first row, records up to date: solid green when your imports cover the last trading day, pulsing red with how many days behind when they don't.
  • Altimeter says so too: a bar under the header when its numbers are older than the last trading day, with a link to import.
  • Didn't trade? One click marks the day as no trades, so the light stays honest.
v0.4.0 · October 9, 2026

A smarter import, and a sharper Tape

  • Import reads TopstepX, Tradovate (and NinjaTrader web), NinjaTrader 8, Rithmic R|Trader (Apex and other Rithmic firms), Quantower and Tradervue files by themselves, and pairs files with one row per buy or sell into trades.
  • You see every trade and its P&L before anything is saved. For other files, match the columns once and Tapeworm remembers them.
  • The 240m 3/10 card now matches thinkorswim: it counts the forming bar, adds the slow line, calls out the fast/slow cross, and draws a small oscillator chart.
  • The Tape refreshes itself every five minutes while you're on it, and each walls reading shows the time it was taken.
  • The chart says when today's EM band will lock, until it does.
  • Accounts: your label shows everywhere, two accounts of the same kind must have different labels, and you can rename an account in Settings.
v0.3.1 · October 6, 2026

Privacy and page analytics

  • The privacy policy now names our page analytics (Vercel Web Analytics, no cookies) and the provider behind Moneyness's longer answers.
v0.3.0 · October 5, 2026

Crude oil and gold on the Tape

  • CL and GC join ES, NQ and RTY: dealer walls, the expected-move band (locked from each product's own session open), and the chart shading for their own trading hours.
  • Moneyness can walk you through Tapeworm itself: adding an account, importing, the trade drawer, the calendar, filters and more.
v0.2.0 · October 2, 2026

Tapeworm opens for the beta

  • tapeworm.app is live for beta testers: the Tape, Blackbox and Altimeter, free during the beta.
