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.
If one don't know about the perfect timing of entrance and exit then there is no need to be involved in trading as trading is not possible without the knowledge of necessary things. Although at start everyone is in fear so they make wrong decision but if one don't learn from mistakes and regularly lossing due to misunderstanding so its a foolish idea.
Sometimes market become green but users wishes to wait more so they are also going towards wrong path which will lead you to the miss your destination. keep your eye on price then go with it if you desires to make beneficial decisions that will be in your favour. Know about the signals and timing to get the maximum advantage and don't be too lazy or too quick in making decision.
