Just exited my position after the funding rates flipped—brutal timing honestly. The apr structure suddenly became more favorable on another major platform, leaving me scrambling to adjust. What frustrates me most is how quickly these rate dynamics shift. Earlier entry on a different asset faced similar whipsaw action. The unpredictability of how capital costs swing across venues makes it genuinely tough to maintain consistent positioning. You plan your entry based on one fee structure, then overnight the math changes entirely.
