There are never certainties when trading. No charting can perfectly predict behavior of an entire market, whether manipulated by makers, influenced by algorithms, or dangling between retail bulls fighting against retail bears.
The best you can do is find something you trust and stick to it. And there's no one answer.
And to your specific issue, there's multiple strategies that do wait for confirmation of reversal and can limit losses if incorrect. Beer candles, also known as Heiden-Ashi candles, if properly used, are a phenomenal way to make sure you only enter after a reversal or after a period of indecision. This way, though you might not bottom tick, you stand a great chance of catching the trend. This is because the nature of the candle is an average of the period. It starts at the middle of the body of the last candle. So if it is pointing up with no lower wick, you are in an uptrend.
It won't make you rich to merely trade using these candles. But it will tell you when the trend are starting and give you decent warning that they have ended. It is up to you to put on protection through stops and hedges if a trend that you have entered does fail quickly.
What makes people really good is when they can line up 3-4 indicators that they FULLY understand. One might signal entry. One might signal overbought / oversold. One might signal institutional interest. One might signal potential of reversal. There's lots. Many many here will give insight and do regularly as to one's they trust.
Long story short, you cant be perfect. But you can employ sound and consistent strategies to give yourself the best chance. And many here are picking up on these through learning from others. It's amazing to see it work. The most successful traders are closer to a mile deep and inch wide than vice versa. The biggest obstruction, and I speak for experience, is attempting to become a jack of all trades.very few even have the time for that, even if they do have the intellectual capability.
