If your buy signal fires and I can still lose half my position before it ‘works,’ then what exactly did the signal signal? It didn’t tell me *when*, it told me *eventually*. DCA already assumes *eventually*. Except with DCA, I skip the hundreds of hours of chart-staring, the false conviction, and the psychological torture of watching a ‘confirmed’ signal bleed out for six months. So what’s the edge? You spend hundreds of hours overfitting a signal to historical data, backtesting every variable to death, and then tell your audience a 50% drawdown is ‘within expected range’?
