A phrase well describes that "slow and steady wins the race", in trading if we keep working slowly and effectively then we will automatically gain success. but if we want to earn hurriedly then the same forex can change its way and we fall in loss over loss. So yes if we step forward after learning and thinking about working there then it will never face us loss but if we do not know about their main conditions and just want to earn money from any source then we may face loss in trading.
