Maybe this is a dumb question, but it what stops Aviva from publishing new prices every minute or every second?

> prices for the funds were published each Friday, and clients were allowed to switch funds at those prices anytime before the next price was published, even if markets moved in the meantime.

Publishing prices every Friday just seems like a formality, from what I can gather it isn't written in the contract.

I suspect the contract is written such that the prices are to be given to the customer each Friday, and the customer has until the next scheduled delivery on the following Friday to reallocate their funds. Aviva could publish more often but it wouldn't change anything.
