What you need to work on is finding actual setups with edge. When you are right you need to make a lot and when you lose, your risk should be limited. This is the core of profitable trading...
...It will take thousands of hours to develop and years to master, there is no way around it. This is what it takes.
I agree with you.
Most young traders concern themselves with entry, and entry is 1% of a method, risk management is 99% of a method and it entails much. Part is what is happening before the trade, where price is, beginning of new trend, middle, end? buying into resistance, selling into support, Trendlines off 60 minutes, daily, weekly, different patterns of S/R, and of course bar by bar patterns of timeframe you trade, some days 90% of trades are invalid cause the risk too great. Then, your signal you say you get in too early, so you not waiting for deep enough retracement, this is often a youth mistake of wanting to get in as nervous tension of possible missing the trade, there will always be other signals. Better the entry, usually means less risk and more profit potential. Then there is managing the trade after you get in, have to be able to identify price action for signs of price slowing down or speeding up. Some of this is of the 10,000 hours to learn how to read price. And learning where much of retail traders get in or exit is also bonus information. Helps to be able to read volume.
Price do go up and down, how high is high and how low is low, buy the high and sell higher, buy low and sell higher, but can you define TREND? So unless you can have answers in a split second, you not ready to trade live.
There are those who hope for luck and this is often hopeless, and other's make their own luck by understanding their profession.
Good luck.
