Trading can be quite challenging mentally, both when things are going well and when they aren’t. There are so many traps that must be avoided when trading:

-Discipline: Sticking to the system
-Greed: Not bending rules looking for always bigger returns
-Looking for home runs: When a trader is losing money, it can be very tempting to take extra risks to win back those losses
-Holding losers: It can become very tempting to keep a losing trade until it “turns around”
-Overtrading: Looking for quick results with displaying patience
-Trading on history: You get in trouble when you start trading based on the results of other trades.
-Overconfidence: Taking risks based on the assumption that you have “superior skills”

Keys to being mentally strong when trading
There are many important things to consider when you are trading in my opinion:

-Avoid emotional decisions: As much as possible, avoid trading on emotion
-Create trading rules that must stick to (entry points, stop losses, etc)
-Do not makes exceptions..once you start there is no end
-Do not doubt your system every time a trade goes wrong.. no system is perfect, the goal is winning more than losing
