Use of snapshots

Older than last sale? But sales come in all the time! Wouldn't that invalidate your snapshot history every few seconds?

I ment the item from that snapshot.

So we make a scan of our owned guilds. In all guilds we find item A.
Guild G1 has item A for the prices: 5, 100, 120
Guild G2 has item A for the prices: 40, 120

Say the history gives us a normal of 60.

So we scan another guild, we find item A there and the price sugestion gives us a nice price. And rounds it down to 40 because thats the price of G2.

But then we get a sale history for G2 for item A. (that might be the first price but that is not for sure)
Then we still round down to 40 because we still think it is there. But it is not trusty anymore that it is right?

I am just guessing herre. But the point is, If i need to scan my guilds every day to get a trustful price. That would take 10 minutes each day :P

Ah yes, I understand now. That makes a lot sense. When this happens, would you invalidate the snapshot data only for the item on the guild in question?

[JordyMoos]

Yea only for the guild in question. But i do not really invalidate the snapshot because the snapshot does not know about sales and also does not care. For the momemt i think the best solution is that price sugesstion figures out if the snapshot for that guild and item is old. In that case it ignores the effect of the last function?
