Patience is one of the most significant qualities that any foreign exchange trader wishes to develop and it is especially so of scalpers who sit watching the market, infrequently for hours at a time. It is easy to think that you see the conditions coming right and then to jump in thinking you may maximize your profits by getting in early. You did not have the patience to hang about for the signal set by your system. Over trading in this fashion almost always leads to losses in the long term.
Patience is also needed in another situation : when you missed and opportunity for a trade. The temptation is to jump in and chase after the price, but it can easily rebound on you. Better to wait patiently for the next real trading opportunity.
Many of us believe that currency exchange scalping strategies will bring them big profits terribly fast. This is not true. Most scalping systems do not make many pips on each trade. Many newbs are unhappy by this and quickly start trying for more.
It is tantalizing to let a trade run when you should be closing out, looking to get bigger profits than your system allows for, but doing this may potentially just leave you losing the tiny profit that you nearly gained.
