There is no magic indicator to make a killing entry into your positions. You should use a combination of indicators like EMA, MACD, RSI and gut feeling, which you could develop only after extensive observations in the market and many months of trading. This is not something that could be taught in few posts. If you are beginner you should start with demo account and test on it many indicators and combination of indicators till you achieve some positive return with them.
Why I often make mistake in entry point, what is the best indicator to know when to entry
You should try out different indicators/strategies using the demo account to find what is the best indicator(s) that suits your trading style. There is no best indicators. You have to do it by trial and error and made adjustment accordingly to achieve the desire results. This will take time and you have to be patience.
As said by others, there is no "holy grail" indicator. And if there is, if everyone has access to it, then it will quickly become completely unusable and completely false. Try out strategies that you can find over the internet. Try and see what works with you, since the only strategy that will really work with you is your own one.
Good luck on your journey,
good entery points for inter day or swing trading could be --> 200 EMA on hourly and four hourly chart.... the price moving above that line would be a buy signal and below it could be a sell signal....
