I have to agree.The beginners have many bad habits which lead them loosing money and some genius minds looses more while chasing their lost money. In fact they need a good mentor like it is required in any other field.
Because they tend to stare at monitor for hours and this is mentally exhausting. You start to ask yourself after every retreat, seeing as your profit sink, if you have to close your order to avoid further decrease in gains.This risk to reward understanding is the bis mistake by newbies They do not wait enough for TP to be hit and hurry to close the profitable trades in less profit while they let stop loss to be hit for more trades.
