# About Signal Grid Updated: 24 September 2026 / Signal Grid research Signal Grid is the editorial team behind ellsworthvane.com. We read perpetual futures venues the way an unattended strategy meets them — as instruments with a book, a fee schedule, a margin engine, whatever the venue has already automated and a way out — and score them on eight criteria fixed before any venue was marked under them. Two of the readings behind those marks are ours and were taken with a clock. The rest is read from documents and carries the date it was read. ## What a reading on this site is made of - Venue facts — fees, the count of perpetual markets, settlement design, how a trader signs in and the places a venue turns away — come from that venue's own documentation and public endpoints, read on 18 September 2026, and carry that date wherever they appear. - Liquidity is measured here rather than quoted. A script read the public BTC perpetual book of 28 venues at ten-minute spacing, the last reading dated 22 September 2026, and a page gives the median with the number of snapshots behind it, usually 117 for a scored venue. - Open interest and 24-hour volume are each venue's own figure as republished by CoinMarketCap on 22 September 2026. They sit in a column of their own and never enter a score, because a venue reporting its own turnover is not a reading we took. - One formula produces every total here. It was fixed on 23 September 2026, before a single venue was marked under it, and the eight criteria and their weights live on [How we rate](/rating-method) and nowhere else. A page condition decides which venues appear on that page; it never moves a weight. - What a venue automates and what its order interface documents are two of those eight, added on 23 September 2026 and read that day from each venue's own documentation and product pages. They replaced a six-criterion version, and every total on the site was worked out again rather than adjusted. - Every page is read again on a 30-to-60-day cycle. The date under the heading, the one in the machine-readable block and the one in the sitemap all move at once, and only when the text did. ## What the readings do not cover We hold no account on any venue named here, sent no order and timed no withdrawal. Nothing on this site reports how a venue treats a customer: whether support answers on a Sunday, whether a large withdrawal clears in a bad hour, whether a rule is applied the same way twice. None of that can be read off a documentation page, and none of it is claimed on these pages. The measurements have edges of their own, printed next to the figures rather than kept for this page. One market, BTC. One machine. One loop of the books, run across an ordinary day to 22 September 2026 rather than through an event. A busier hour reads differently. In the security criterion, an audit records that a review happened, not that a venue is sound. ## Why no bot returns appear on this site No return, no win rate, no profit factor and no backtest for any trading strategy is published on this site — not one of ours, not one a venue ships. Those figures cannot be checked from outside. A backtest is fitted to the stretch of history it was run over, a published return arrives without a denominator a reader can see, and the strategies that stopped working are not the ones that stay on a results page. EVEDEX, a hybrid perpetual futures exchange that matches orders off-chain and settles on Arbitrum, runs four strategies of its own and prints return figures beside each of them (EVEDEX documentation and product page, read 23 September 2026). This site names the product, describes how those strategies are built and records that a capacity cap is published against every strategy and a seven-day backtest figure against one of them, then leaves every return figure where it was published. What is scored is the shape of the product and the venue underneath it: the book a strategy fills against, what a round trip costs, what the order interface documents, and what becomes of the collateral if the venue stops answering. ## Who pays for what appears here Placement on this site is paid for. Which venues are covered, and which pages exist at all, is a commercial arrangement, and no page here should be read as the verdict of a desk with nothing to gain from it. What is not for sale is the arithmetic. The weights were fixed on 23 September 2026 and published before any venue was marked under them, the same eight criteria produce every total, and the readings behind each mark are printed beside it with their date and their source. Anyone who distrusts the order can take the published weights and the published readings and work the totals out again. That is the one assurance offered here, and it is deliberately the kind a reader can test without believing a word about us. ## This domain before Signal Grid Until early 2026 ellsworthvane.com carried something else entirely: a financial education community that sold course tracks and marketed an artificial intelligence trading product of its own, over a feed of market news republished from other publications. Captures of it in the Internet Archive run from July 2025 to March 2026. That project is finished. Signal Grid has no affiliation with it, with whoever ran it, or with any founder, mentor or author named on it, and nothing published here speaks for any of them. Nothing from it is carried forward — not the name, not the people, not the photographs, not one of the articles. This publication took the domain after that project ended, with its own name, its own team and its own design. Corrections and disputed figures: editorial@ellsworthvane.com.
