Despise all the strategy being applied, trading is not 100% guarantee but if proper analysis is being put in place at least your wins will be more than you lost, and you can be said to have made profit...
If you do not adhere to risk management, you will lose your money anyway, since you will not be able to open an order in the right direction every time with 100% probability. Thus, you should minimize the loss as much as possible if the price goes in the opposite direction to your expectations, so that this does not affect your deposit as a whole.
