Glass Almanac is an independent guide to crypto derivatives data: open interest, funding rates, liquidation feeds, and the dashboards built on top of them. CoinGlass is the best-known example of that kind of dashboard, so it is the tool we write about most. We are not CoinGlass, and we are not an exchange, a broker or a data vendor.
The reason this site exists is narrow and specific. Derivatives dashboards present modelled estimates and measured observations in the same colours, on the same screen, with the same air of authority. A liquidation heatmap looks as solid as a trade print, and it is not. People move stop-losses on the difference.
Who runs this site
Glass Almanac is a small editorial desk, not a newsroom and not a research house selling signals. The people writing here come out of derivatives trading and security work rather than crypto marketing. The perspective is unglamorous: exchanges throttle their own feeds, aggregators inherit those gaps, and the resulting numbers get quoted for years without anyone checking the footnote.
We publish in English and localise the four main guides into several other languages. The utility pages, this one included, exist in English only.
What we cover
Our subject is the data layer, not the trade. We explain how a metric is constructed, where it comes from, what it can and cannot support, and what it costs. We also cover platform mechanics such as pricing tiers, app releases, account requirements and phishing risk, because those are what readers search for when something has gone wrong.
We do not cover token launches or price commentary, and we have no view on where any asset is going. If a page reads like a trade idea, we have failed and we would like to hear about it.
How we research a page
Every page is written against a research dossier compiled before drafting begins. The rules do not change.
- Primary sources first. A platform's own documentation, pricing page, API reference or store listing beats any write-up about it.
- Every figure is attributed in the prose, so a reader can check it without hunting.
- Volatile figures carry a date. Derivatives data changes by the second, and an undated number is a liability.
- Where two credible sources disagree, we publish both and name them rather than picking the tidier one.
- Where a claim cannot be confirmed, we say so on the page. "We could not verify this" is a finding, not an omission.
- We paraphrase. Short attributed fragments aside, we do not reproduce other people's sentences.
Measured, modelled, unverified
This is the spine of the whole site, so it gets its own heading. A measured figure is something an exchange or an index actually reported: a settled funding rate, a published open interest number, a store listing's version string. A modelled figure is an inference produced by somebody's algorithm from assumptions they usually do not publish. Liquidation heatmaps are modelled. So are risk composites with undisclosed weightings.
Why the label matters
A measured number can be wrong because a feed was throttled. A modelled number can be wrong because the assumption behind it was, which is a far harder failure to notice. Both appear on the same dashboard in the same colours.
Corrections and revisions
We get things wrong. When we do, we want to know quickly. Write to contact@coin-glass.app with the page URL and the source that contradicts us. Corrections of fact go to the front of the queue.
When a page changes materially, we change its updated date. Corrections are made in the text rather than buried, and where a figure has moved we say what it was and when it was accurate. We do not silently delete claims that turned out to be wrong. See the contact page.
How the site is funded
Some outbound links here are sponsored, and we may earn a commission when a reader uses one. Those links are marked wherever they appear, and they sit in fixed positions inserted by the build system rather than sprinkled through the prose.
What that money does not buy: a mention, a ranking, a rating, a softened criticism, or sight of a draft before it goes live. No advertiser has ever reviewed a page before publication, and none has ever changed an assessment after it. If a commercial arrangement conflicted with something we needed to publish, we would publish it and lose the arrangement. The full commercial position is on the disclaimer page.
What we will never do
- Give financial, investment, legal or tax advice. We hold no licence to do so and do not want one.
- Predict a price, publish an entry, a target or a stop, or suggest a strategy is profitable.
- Recommend leverage, or imply a modelled level is a safe place to put a stop-loss.
- Accept payment for a positive review, a ranking position, or the removal of a criticism.
- Claim to be CoinGlass, imply their endorsement, or present a sponsored venue as official.
- Ask for a seed phrase, a private key, a password or a two-factor code. No one legitimate ever will.
Reaching the desk
One address handles everything: contact@coin-glass.app. Corrections, translation errors, press questions and commercial enquiries land in the same inbox and get an honest answer. What we cannot do is help with an account on someone else's platform, because we have no access to one.
Frequently asked questions
Is Glass Almanac affiliated with CoinGlass?
No. Glass Almanac has no commercial, corporate or editorial relationship with CoinGlass or with Coinglass Technology Co., Limited. We write about the platform the way a reviewer writes about a product: from the outside, using public sources. The official CoinGlass site is coinglass.com. We cannot access, modify or recover anyone's CoinGlass account, and we never receive payment from them.
Do sponsors get to see articles before publication?
No. Sponsored placements are outbound links inserted by our build system in fixed positions, and they are labelled as advertising wherever they appear. No advertiser reviews drafts, suggests wording, requests changes or receives advance notice of what we publish. If a commercial partner ever asked for a favourable assessment, the answer would be no and we would say so on the page.
Why do you keep saying a figure is modelled?
Because the distinction decides whether a number is safe to act on. A liquidation heatmap is built by estimating leverage from open interest, not by reading any exchange's risk engine. CoinGlass itself says actual liquidation amounts may come in below the levels shown. A modelled estimate with a few percent of error is a very different object from a measured trade print, so we label it every time.
