Both sides work against this trade now: funding costs −$33 a day on $10k at the current rate, and Binance is 0.025% cheaper against Bybit than usual: you would sell low and buy high (−$2 if the spread goes back to its 7-day average of −0.139%). Swap the legs. Mind the row above: over the last 7 days funding on this pair paid +0.096%, so the current rate has only just turned against you.

The current funding rate is far above what this pair has been paying: over the last 7 days it paid 0.096% in total (about 5.0% a year). A funding rate is set anew for every payment; at this rate the next one is about −$5.54 per $10,000. In the chart: green and red are payments made, yellow is the current rate, not paid yet.
