Rate at the time of a transfer and average purchase price

I have made some transfers between my accounts - and PP creates an inbound and an outbound. When doing the transfer, you are asked a rate for the security. Should that rate be:

  • the average purchase price - and if it should - how do you find the average purchase price?
  • the rate of that particular day for the security
  • something else?

The second option.

@chirlu But the security themselves has not changed value. Is that because the security needs the current value to be able to calculate correctly the values for gains and losses. Won’t changing the value of the security suddenly change the unrealized gains with realized gains in PP?

It depends on the report. Some (security-centered) will ignore the transfer altogether, others (account-centered) will treat it like a buy/sell.
