Where you said “In the example you cited in your question (long 2,000 units of EUR/USD), you are betting on a price rise in one unit of EUR/USD times 2,000 units” ----- So it’s like saying I think the Euro will rise against the dollar by 2000 units - E.g. - if the exchange rate was 1.5000 - I bet it will be 1.7000.
Am I right in thinking that? [/quote]
No, apparently I didn’t make it very clear. Let’s use an example.
Suppose your analysis leads you to conclude that the EUR/USD will rise in value. Let’s say it’s currently EUR/USD = 1.1800 (using round numbers and 5-digit pricing for convenience). And let’s say that you are considering two possible trades in your USD-denominated account:
(1) go long 1 unit of EUR/USD and (if your analysis is correct) collect your profit
(2) go long 2,000 units of EUR/USD and, again, collect your profit for being right
What would be the outcome of these two trades, if the price of EUR/USD rises by 50 pips to 1.1850 ?
We observe that 1 pip is 1/10,000 (that’s one ten-thousandth) of one USD. In numbers, that would be $0.0001. So, the two trades would produce profits, as follows:
(1) in trade #1, 1 pip is worth $0.0001 per unit, and 50 pips is worth $0.0001 x 50 = $0.005 (which is one-half of 1¢). That’s your profit on this one-unit trade, if EUR/USD rises by 50 pips, as you predicted. Half-a-cent profit is not worth your time to even bother with, is it?
So, what about trade #2?
(2) in trade #2, 1 pip is worth $0.0001 per unit of EUR/USD x 2,000 units in your trade, which equals $0.20 per pip. And 50 pips is worth $0.20 per pip x 50 pips = $10.
In trade #2, your profit is 2,000 times as large as in trade #1, because your position size is 2,000 times as large.
I hope that helps to clear things up for you.
