Funding rates are a mechanism for exchanging long and short funds set by cryptocurrency exchanges to maintain the balance between perpetual contract prices and underlying asset prices. The exchange does not charge this fee, but adjusts the holding cost or profit by having longs or shorts pay each other funds at regular intervals, prompting the contract price to return to the underlying asset price.

When the market is bullish, the fee rate is positive (long pays short), and when it is bearish, it is negative (short pays long). When the fee rate is 0, both parties do not need to settle. Taking Bitcoin as an example, the fee rate usually ranges from -0.375% to 0.375%.

The color logic for visualizing the table is as follows: when the rate is equal to 0.01%, it appears in black (baseline); when it exceeds 0.01%, it appears in red, with darker shades indicating higher rates (stronger bullish sentiment); when it is less than 0.005%, it appears in green, with darker shades indicating lower rates (stronger bearish sentiment).

This is a historical chart of BTC funding rates, used to display the changes in funding rates on different exchanges (such as Bitmex, Binance) in virtual currency perpetual contract trading, as well as the price trends of virtual currencies.

Green bars indicate a bullish trend, while red bars suggest bearish strength, assisting in predicting short-term trends; extremely high/low funding rates may signal a 'long and short squeeze,' posing risks of price reversal or volatility; when the fee rate on an exchange significantly deviates from other platforms, one can attempt arbitrage by shorting on high-fee platforms and longing on low-fee platforms; rising prices accompanied by increasing funding rates (lengthening green bars) indicate bullish sentiment supporting the trend, while falling rates should be watched for signs of weakening uptrend. This serves as a 'sentiment dashboard' for crypto trading, helping to understand the dynamics between long and short funds and aiding in trade decisions.
