In the end, there is no practical difference (profit and loss is the same), but it can make bookkeeping a pain in the ass.
Thanks for your earlier post. I find the different ways people approach FOREX endlessly fascinating. My own goal (I'm not there yet) is to use the most stripped down simple method I can consistently win with and take advantage of the endless scalability of FOREX to make my money.
You can, with a big enough position, live like a king for a year off one pip. My goal is to live well off a handful of pips a day made before I'm done with breakfast.
