What funding measures
Funding arrangements commonly help connect perpetual prices with a reference market. A positive or negative rate describes a payment convention under venue rules, rather than a reliable forecast of the next market move.
Three components of a result
A position has price profit or loss, funding payments and execution costs. Leverage affects these relative to the posted margin. A favorable price change can still leave a poor net outcome after costs, while collateral pressure can force an early exit.
Rules before conclusions
Check funding intervals, mark prices, maintenance requirements and liquidation procedures. These conditions differ across venues. Research should describe the actual contract rather than infer its terms from the product name.
