Patience - you don't have to buy at that very moment and you don't need to buy with whole budget
Read news before entering the position on ever particular currency
Don't be greedy, take a smaller profit and get out of the position when the green candles look great, there will always be more opportunities.
Don't regreat missed opportunities and trades where you could have done better by staying longer in it because you don't even notice all the situations where you did good by shorting the position on time, you take it for granted.
Buy on dips, if there is nothing happening on the marked better wait and do nothing then buy expensive just to get entertained.
