Problem is that this requires a longer approach. Note that my post was a little sarcastic. I said "some dozen millions" - so your 20-25 are on the LOWER end of what I actually mentioned. "some" being more than "a pair".
I basically wanted to point out that while you may have problems clearing 10 billion, the limit is so high it is not something to be of convern, unless you are in mostly for 2 minute trades.
Maybe my irony was a little too light.
