Information about mechanics. Not advice, not a forecast, not a recommendation.
By using this site you accept these terms. If you do not, stop using it — there is nothing to cancel.
A published record of what perpetual futures cost to hold on several exchanges, computed from those exchanges' own public endpoints, together with calculators that show the arithmetic. It is information about mechanics.
It is not financial, investment, tax or legal advice, and nothing here is a recommendation to buy, sell or hold anything, or to use any particular exchange. No figure here is a forecast. Leveraged crypto derivatives can lose more than the amount deposited.
Whether these products may lawfully be offered to you depends on where you live. That is your responsibility to establish, not ours, and this site is not directed at residents of the jurisdictions named in the footer.
Figures are read from public endpoints at build time and are stale the moment they are published; rates move continuously. Fee schedules are quoted as observed on a stated date and exchanges change them without notice. Where a figure could not be verified, the page says so rather than filling the gap. Nothing here is warranted to be accurate, complete or current, and you should confirm anything that matters against the exchange itself before acting.
Links to exchanges carry a referral code, and we receive a share of the trading fees of accounts opened through them. This costs you nothing extra and in most cases returns part of those fees to you. It does not change what is measured: the numbers come from the exchanges' endpoints and are published whether they favour a partner or not.
To the extent the law allows, we are not liable for any loss arising from use of this site or reliance on anything published here, including trading losses. Nothing in these terms excludes liability that cannot lawfully be excluded.
These terms may change. The version on this page is the one that applies.
