It may be tempting to try to predict where price movement is headed, but some variables in the markets are impossible to foresee. No matter how confident you are in a trade, there is no way to guarantee that it is going to be a winner.
Same thing applies to an account manager. No matter how competent they are, drawdowns will be inevitable, which is why it is important to make the difference between normal market events and incompetence.
Anyone pretending like they can predict the outcome of a trade, or pretending that they never lose are blatantly lying.
One of the most frequent causes of volatility in the markets is big economic news. It may be the release of new employment statistics, a new trade deal with a country, or anything that can influence the economical situation of a country and its currency.
By being a technical trader, you take the risk of unforeseen events surprising you and derailing your trading plan.
Even if you choose to trade based on fundamental news, there are certain events that will be too complicated and unpredictable to take into account. It is possible that you correctly determine that the results for a certain report are going to come out as positive, yet still be on the wrong side of a movement. How people react to news is the most important variable, which is highly unpredictable.
You will have to accept the fact that some trades will be taken out by unexpected volatility before you can achieve consistency.
Other Market Participants
To truly understand how easy it is to lose a trade, you should keep in mind that anyone in the market with deep pockets could take you out of a trade.
You never know when a huge transaction is going to be made, pushing the price to trigger your stop-loss. No indicator can predict how other market participants are going to act, at least not yet.
Taking this into account is necessary to progress and to learn how to control your emotions. It will help you accept that you should never be angry at the market or at the chart, as it is only reflecting the decisions of other traders. To be a perfect trader and to only enter winning trades, you would have to read the minds of everyone currently opening and closing trades in the markets, which will never happen.
Unexpected Price Levels
However confident you are in a trade, there are probably certain variables that you are not seeing. Maybe a very significant moving average is going to be tested. How are you supposed to be aware of this level if you are not using moving averages? You cannot possibly expect to take into account every single indicator or every significant price level.
You would also have to look at every time frame possible, and perfectly analyse every single possible combination of timeframe and indicator simultaneously, which would be foolish to try.
Important Mindset: Lower Your Expectations
The point of trading is to make money. If you are consistently making money, either by trading on your own account or with an account manager, then you are already better off than 90% of the people.
It is not a game of having less losing trades than others, or having the longest possible winning streak. You could lose twice as many trades as the next trader, but make twice as much money as them.
Many traders try to keep their record sheet as perfect as possible simply to impress their entourage. If that is your case, you should rethink your philosophy before it starts becoming a problem.
