Calculating the amount of risk is very important if you follow your money management strategy carefully. I advise you to use it every time you open the Forex position manually. It will take you a minute of your time but it will save you from losing what you don’t want to lose. Calculating the size of the position is also the first step in organizing your forex trading which is definitely a feature of the professional forex trader.
The importance of thorough position size calculation is emphasized in forex books. Position size should be done along with setting the correct stop-loss and take-profit levels. It is difficult to lose all the money in your account if you manage risk and position size every time you enter the Forex market.
