Does the Grand Exchange have a pattern of when it updates prices?
I'm not talking about items like half wine jug. I mean more like items from the top 100 traded list.
It never seems to be the same time during the day. It has to have some sort of pattern unless it waits for certain items to hit a certain volume
It updates once per day between 3am and 9pm GMT (or +1 hour to both times depending on daylight saving or w/e). This timing was always random, and unless they have changed it I highly doubt anyone has cracked the code. Suppose the GE picks 15:00 for an update time today.
At (or by) 15:00, every single item is considered for a price update. Each item has a "quota" which needs to be achieved in order for the price to be updated. This quota can be considered to be a points value. One successful trade may be worth 10 points. One GE offer may be worth 1 point (This is just an example - no one knows the ins and outs of this system, however items can update without any trades occurring - hence my 1 point comment). Something like yew logs will no doubt have a much larger quota than third age or your half wine example. So, all items are considered simultaneously, but different times on different days. The GE doesn't wait for items to "hit a certain volume" (=quota) - instead it just doesn't update their price if this isn't hit and waits to check again the next day. It also is cumulative, which is why items like the half wine do eventually update.
There are no doubt some subtleties to this to stop price manipulation by trading amongst friends or putting lots of really low buy offers or really high sell offers, but this is the idea.
