Thanks, this is what I was missing, it didn’t make sense that I could trade large amounts of units with a low deposit, unless somehow i am being borrowed money. This is where the Leverage thing comes in but I have not read enough on it.
Since you say I am under leveraged in this case, does that mean there is a way to use leverage to my advantage without falling in debt with the broker?
What you wrote is correct, except for the phrase per pip (which I deleted in your quote, above). Pips and pip-values do not factor into the simple formula for actual leverage used –
Actual leverage used = notional value / account balance
For every GBP-pair except EUR/GBP, one standard lot (100,000 units of GBP) has a notional value of £100,000.
(For the EUR/GBP pair, the notional value of one std. lot is 100,000 * EUR/GBP price.)
