hello that depend on lotsize you are trading and also with leverage for ex:if you have $100 and if you open 5lotsize(instaforexlots) then it take 20pips to double your money but it will also have same disadvantage of blowing your account with 20pips if price goes against you withdraw your whole profit in this trading company because you r friend will be have too much wrong things so may be he is doing cheating with the company , so i think i withdraw profit at any time and they gives me without any limitations , and also in your profile there will be two option if you choose withdraw with safe bonus then your bonus will be remain in your account and profit
