This article deals with a very basic concept of currency trading that  for some unknown reason seems incredibly difficult to master (speaking  from my own trading experience)
I like to use simple scenarios to explain some of the huge forex trading pitfalls:
Shopping Trip Reality 
Have  you ever felt like you "missed out" because you left too many pips on  the table? You might be happy with your +50 pip gain - that is until you  see the currency trade go +150 more pips in your direction. What about  when you "cut your losses short" only to see the trade reverse and go  back in your original direction.
The reality is you will NEVER  get all the pips that the market has to offer - it is simply  impossible. The quicker you accept this - the more brain cells you will  save from being stressed out.
I call this tip Shopping Trip Reality  - because have you ever gone to the grocery store and walked out mad because of all the groceries you didn't buy. I mean there is a WHOLE STORE that you could have had - right?
This  seems silly but it's the same with forex trading. Get in the market  & take the pips that you can and then leave the market (in other  words shut off the your trading platform for the day)
The next time you find frustration creeping back into your mind because of the "pips that you missed" - simply think: Shopping Trip Reality.
