Traders needs to learn when is the right time to enter the market and not to judge when to enter with a particular signal. Signals are unprecedented and may change faster than it's expected.
The right time to enter the market really determines the success of trading, but it's not an easy thing to do because it's the same as knowing which price is the highest and also the lowest price, all you can do is predict or analyze but it won't be 100% correct, but agree to start trading not always when the market starts to turn green because consistent traders who often trade understand that even in red market conditions they can still enter the market and benefit from the red conditions, continue to carefully learn each state both green and red so that trading does not always depend on just one state.
A good and experienced trader will benefit from any market condition, whether it's red or green because they have so much knowledge and experience about the movements of the market that they would at least have a general idea of which way the market will move next and they place their trades accordingly, even when the market is green, you might have to face losses and even if it's red, it doesn't necessarily mean you should buy.
A good trader is someone who can easily determine which time is the best for them to buy or sell, you can't just buy when it's red and sell when it's green, that's now how trading works, I say that because lot of newbies think that as soon as the market becomes green, everyone gets in profit which is not true.
