I just realized something pretty interesting about how funding fees are calculated in futures trading that many newcomers might not have noticed. Usually, coins with high volatility in futures will have a high funding rate, and this is actually an opportunity to earn fees if you know how to play.

The principle is simple: when the Long/Short ratio is unbalanced, a funding rate is created to balance the market. If the funding rate is positive (meaning more Longs), then Long traders have to pay fees to Shorts, every 8 hours. Conversely, if the funding rate is negative, Shorts will pay fees to Longs.

Let me give a specific example: you open a $100 position with 50x leverage, so the total volume is $5,000. If at that moment the funding rate is 2%, then the fee you will pay is 5,000 x 2% = $100. This number is not small, especially if you plan to close the position gradually without paying attention.

The way to calculate funding fees is also not complicated: positive funding = Long pays Shorts, negative funding = Shorts pay Longs. Understanding this is the key.

Now for the best part — how to hunt for funding fees. This trick I usually apply about 5 seconds before the funding period ends. At that moment, I open a position in the favorable direction: if the funding is negative, I open a Long to receive fees; if positive, I open a Short. Immediately after receiving the funding fee, I close the position. Why? Because after funding occurs, the price often moves in the opposite direction, making it easy to get liquidated.

The calculation of the funding fee and the timing of closing are two crucial factors for the success of this strategy. Has anyone tried this before?
