PerpA useful first visit takes one contract
Open the funding workbench and choose BTC, ETH or SOL. Binance appears first. Select the platform or contract name to open its details; the percentage alone does not tell you its interval or settlement status.
Look for the source label and fetch time before interpreting the sign. A positive rate means longs pay in the usual funding convention; a negative rate reverses that direction. The rate is a percentage, while an account funding entry is an amount. The payment guide walks through the difference with changing position sizes.
The Binance number is present, but some actions are paused
That is an intentional boundary of the current feed. Coinalyze supplies predicted funding for the three Binance contracts. Our integration has not verified their settlement schedules or obtained actual settlement events. You can inspect and watch the prediction. You cannot use it here for eight-hour conversion, a holding-period charge or an active alert rule.
A fresh price on the heatmap does not fill those gaps. Spot prices, predicted funding and actual funding settlements are three different records. For the exact meaning of the fields, open the source notes.
Add ETH or SOL directly from the watchlist
Choose Watchlist in the sidebar. The contract picker shows BTC, ETH and SOL with a button for each supported platform. Select the combination you want; selecting a saved button again removes it. You can also use the star beside any current-rate row.
The view remembers the exchange as well as the asset. If a saved contract seems missing, clear the asset or platform filter. Adding an unavailable contract does not repair its source or enable alerts.
By default the list is saved for this browser session. Choose Remember on this device only if you want it to persist locally. Both language views use the same list. Clearing the list also clears its associated alert rules. An exported watchlist is a download, not a cloud backup or an import service.
Keep the table beside the chart when checking a payment
Select 7 or 30 days, then switch between Chart and Table. CSV exports the same actual events as that view, across the supported sources that returned records. The details below the chart show coverage and gaps. A missing Binance series is not a run of zero-rate settlements.
Hover over a chart point or use the table to read an event's time and rate. When comparing against a statement, set the page to UTC first. A record near midnight can be labelled with different dates in two time zones.
Set a rule only after checking its status
Add a contract to the watchlist, choose a threshold crossing, a direction change or an approaching settlement, and save the rule. Up to 12 rules can be kept. The threshold input expects percent: entering 0.01 means 0.01%, not 1%.
Rules watch for new changes after they are saved or restored. They do not immediately replay an already satisfied condition. There is a five-minute cooldown per rule. An unverified schedule, stale data or a hidden page pauses the rule; a closed page cannot send an alert. The Test alert button checks the on-page display only.
Use the cost panel as a worksheet
Enter a positive USDT position notional, choose long or short, and inspect the selected contract above the inputs. Historical mode uses obtained settlement events; future mode requires a verified schedule and states its fixed-rate assumption. Both time inputs use UTC.
To include trading charges, enter your own opening, closing and combined slippage percentages. Zero is an initial input, not a claim that trading is free. Keep your position size fixed in this worksheet; if it changed, calculate the relevant event-sized pieces separately. PerpFox does not read or upload your position.
When the page does not behave as expected
| What you see | What to try |
|---|---|
| Old data after refresh | Read the fetch time. The button requests our cache; it cannot force an upstream update. |
| Empty watchlist | Check filters and whether you are using the same browser session or a device where local saving was enabled. |
| Copy failed | Select BN8812 manually. Some browser contexts do not allow clipboard access. |
| Rejected amount | Enter a plain number without grouping commas or scientific notation. Notional supports up to eight decimal places. |
| Paused calculation | Check schedule, freshness and historical coverage. Typing a custom rate cannot create a missing schedule. |
If those checks do not explain the issue, send the page URL, contract and UTC time via Contact. Do not send account passwords, verification codes or API keys.
