Formula for finding out the real current funding rate

API Futures API
1

Hi everyone,

I’m trying to figure out the formula for the real current funding rate, which I’m struggling with. Let’s take BTC-USDT as an example.

The APIs provide the following value: https://fapi.binance.com/fapi/v1/fundingRate?limit=200

{
"symbol": "BTCUSDT",
"fundingTime": 1669132800000,
"fundingRate": "0.00007881"
},

However, on the website I’m seeing a totally different value, which is 0.0035%. Is there some formula to calculate this real value that is displayed on the website? Which one is it? Thanks a lot!

The funding rate on UI is the current funding rate, which is not in returned from the API.

Thanks for answering! But how can I get the current funding rate then? Or maybe there’s some formula to calculate it from the funding rates that the API returns?
Coinglass somehow gets it, both for USDT-M and COIN-M futures: Funding Rates For Perpetual Swaps-Funding Rates Compare-Funding rates arbitrage-Coinglass

I am also experiencing a similar issue. I am using the WebSocket URL “wss://fstream.binance.com/stream?streams=!markPrice@arr” to retrieve funding rates. I noticed that the values are in decimal format, but when I multiply them by 100, I obtain the accurate percentage format.
