Sorry but I cannot agree with this at all!
Many of us veterans have tried many times to explain that losses are not a bad thing - they are the inevitable and integral part of a business/profession that deals in probabilities.
You will never avoid losses entirely nor should you even try to avoid them!!! They are the “overheads” of our business in the same way as any other business has costs to manage in order to make profits.
And the emphasis is precisely and squarely on managing your losses, not trying to avoid them.
You cannot be a trader and make profits from your trading unless you are active in the markets - we all know that. But if you are in the markets then every trade you take has a probability of success and a probability of a loss. The sole aim of trading is to ensure your gains exceed your losses in the most optimum manner.
A loss is only a negative function if the trade was taken/retained for the wrong reasons. Reasons such as contra to method entry rules, too large exposure, moving/removing stops in the hope that it will “come right eventually”, intuitive/spontaneous trades without justification, revenge trades, doubling up to retrieve a loss, etc, etc.
But when a trade is put on according to one’s pre-set rules and parameters then those that lose are totally within expectations and anticipated accordingly.
So how can such losses be ok?
That is the realm of risk/money managment. An issue that is clearly ignored by many new traders. The overall aim is to ensure that you know your overall ratio of losses to gains as well as how much are losses compared to those gains. e.g. if you know from testing/experience that you normally win 60% of your method’s trades and that you normally lose about 30 pips compared with an average gain of 60 pips then you know that you should make a consistent profit over a period of time.
You need to risk losses in order to chance winning.
This is only a very basic overview of the concept but the underlying aim should be not to fear losses but to control them as part of your overall strategy.
Well that’s enough waffle from me for one day!
