Most YouTube indicators promise 90% win rates on a three-month backtest. A real trading system has to answer a completely different set of questions before a single trade opens: what is the market regime right now, how stressed is the environment, how much capital should actually be deployed, and what triggers the exit when things go wrong. Here is the difference, and why it matters more than any signal.
That TradingView Indicator Is Not a Trading System An arrow on a chart answers one question. A real trading system answers all of them, before you ever open a position. There's a formula that has completely taken over YouTube's financial content. Someone pulls up a chart, drops an indicator on it, and shows you 8 trades from the last three months where the arrows pointed up right before the stock moved higher. "90% win rate," the title says.
