If CYB Australia must mirror CYB UK, then by my calculations, CYB should go to $2.37 on Monday.

I get this by taking the low close of CYB in the UK on 5/9, which was £110 GBP up to the close yesterday of £131.50. That is a 19.5% increase.

CYB Australia low close on the 5/9 was $1.985. So increasing that by 19.5% gives $2.37.

I also checked the GBP to AUS exchange rates and they are still similar, on 5/9 it was 1.80 AUD to GBP, and now it is 1.81.

So any thoughts on why it shouldn't start at $2.37 on Monday?
