The enduring futility of indicators in CFDs

Been watching the $GER40 today, up over a percent and pushing 25000. Price action has been fairly clean. My perennial question, especially in CFD markets where leverage amplifies everything, is why so many still cling to lagging indicators as their primary decision-making tool. We see moves like the $KES at 122.55, another grind higher, and while volume might give a hint, a moving average cross tells you what you already missed. It feels like chasing the tail rather than anticipating the dog. Am I completely off-base here, or is there a genuine, consistent edge to be found in them that I'm missing?
