Here are my thoughts on psychology of forex trading...
The biggest battle a trader has is not with central banks, not with brokers, and not with trading algorithms, it is in fact your inner voice and your trading mindset. Many traders burn out due to the fact that trading is an intense psychological battle of fear and greed and trying to preempt market behavior. Don't worry, even professional traders get it wrong more than they get it right!
A great analogy, and as covered in the chapter on ‘Reality of Trading’, is that of professional golfers, only a very small percentage make a rock-star living from it (approx 0.5%) whereas a few have a comfortable lives (approx 1.5%), even more break even (about 12%) and the rest are mediocre and do not make enough money to get on the radar (majority). Same is true for traders and unlike what many forex marketers promote, trading for a living is a tough gig.
Saying that, trading does not prejudice, does matter your race, your religion, your wealth or even your education, all traders are equal and you are pretty much only as good as your last month.
A healthy respect for the markets is essential and you need to take responsibility for your actions - not everyone gets it right all the time and knowing when to fold and cut your losses is essential as the market may not come back in your favor and it is better to take a 10% or 20% loss than risk being liquidated and losing 100%.
Some questions to ask yourself...
How far are you willing to let a losing trade go against you? (what is the maximum level of draw-down you will accept?)
What win/loss ratio do you expect you will have trading with real money?
Are you prepared to stay up staring at screens half the night to wait for a position to come back into profit from loss?
Can you handle stressful situations where markets are volatile and unpredictable?
Do you realize the difference of trading a demo account to a real money live account?
The biggest aid to your trading mindset is a trading plan and this should have if-then scenarios so that the psychological impacts are minimized as you have a pre-defined plan of action.
The core and underlying driver of trading psychology is FEAR and GREED. Trading decisions are made based on either the fear of losing/risking money or the greed associated with making a profit. This is seen all the time in the timing of the exit and entry of a trade and can take the form of entering & exiting trades too early or too late. Self doubt is the byproduct of the fear and greed foundation and is a constant nagging voice in the back of the head of a trader that questions all aspects of the trading psychology.
So the biggest battle faced by a trader is not the large banks, it is not the brokers, it is not other traders, it is not the central banks, it is themselves.
Handling stress is the next major obstacle that traders need to manage. If a trade goes against a trader then of course stress is going to come into the equation, if a trader has full belief in his/her system then of course the faith in the system should reduce the stress levels applied, however due to the uncertainty of the markets there is always going to be some level of stress, especially when the trade size and consequent risk is applied.
