This discussion was never about the best single metric to use... and the debate about PF began when you ignorantly proclaimed it flawed. You continued to demonstrate your witlessness by claiming that PF as a metric somehow degrades as trade frequency increases, by being clueless of how PF and Sharpe can diverge, and by relentlessly digging yourself a deeper hole here. Are you as resolute about not admitting you're wrong when a trade's not working out?
