Since forex trading is just a trading job like any other trade so you can work as a full time but since it's hard job and need much time to get your experience then you need to invest time before you take it as a full time job ... unless you have no other job and just only started at forex trading then take it a full time from the beginning and don't waste time working in other job ... but wait ... i always say that we need to secure our life while trading ... yes but like every one who begin his life you may work for a couple of years with meaningless salary just to acquire experience ... the same at forex but you must take it serious then as it's your future ... just don't focus at the beginning on profit though it's your main job ... you must take and acquire experience at the beginning to be able to work full time as a forex trader
