Mark,
I've set up the Automatic Retrieve Frequency of quotes every 330 minutes, from 7AM to 7PM. So its achieves 3 automatic retrieves per day: early morning, midday and early evening. Because an historical quotes server is not available for all the investments, with this setting I'm sure to catch the daily close quotes of all investments whatever the time zone (Asia, Europe, America).
I'm very pleased with the behavior of Fund Manager here, except for one thing. Sometimes I need or want to download the quote of a couple of investments manually during the day between two automatic retrieves. In this case the timer of 330 minutes is immediately reset, so the schedule of automatic retrieves is messed up to the end of the day.
Maybe there could a kind of permissiveness to download manually some quotes but without reset the timer?
