I agree with you, because you cannot enter, the only thing that can be 100% suitable, even the same strategy works differently for different traders.
Always search for a good plan and strategy and test before demo account and after it, you can start real trading with a real account.
I'm new to trading and would like to trade with a simple strategy than has lower risk and capital involved. Can anyone recommend such strategy suitable for a beginner?
Buy and hold indices is pretty much the only successful strategy that anyone can do with barely any research, no experience, and not rely on luck.
scalping contains huge risk when time trading in practical but despite of having much practice sometimes scalping can make huge losses.
