They have a direct ID match (probably purchased right before the purchase)

Haven doesnt have any other sales except for what appears to be bulk:

So that can't really be used here.

Also as a general note for everyone as it seems this is an unclear topic:

Buy orders can be an indication that something is low, so its not that they "dont mean shit". Buy orders can actually counter, but there are exceptions. For this its important to understand the difference between generic buyers and someone that wants to buy 1 copy of the hat, as well as some other issues:

1. Generic buyers vs single-copy buy orders

- Generic buyers constitute infinite data points; single-copy buyers only one data point. One data point does not necessarily weigh up against, say, 5 lower sales.

2. Buyers as common trading point

- In some cases, literally every sale happens at buyer's value (or below). Youll typically see the lowest sales being for overpriced hats, and that the person getting the suggested hat for their overpriced hat, they instantly sell it to buyers. In such cases, all (or like 9/10) data points are at buyers value, so they constitute the common trading point. This is similar to how fast sales (~1 day) are used if literally everyone either instantly sells or doesnt sell at all. In such a case, buyers value can be used as data point for a suggestion.

3. Time of listing/"counter-buyorders"

- The time of a buy order's listing is relevant. If a buy order was created a month after the sale, then thats an indication the market has shifted since. One of the reasons that buyers counter, is that whoever took the "low" offer could've also taken X pure, indicating it's just someone making a poor decision. This doesn't work when the buy order wasnt around when he took the low offer.

In conjunction with this, we usually see that once a suggestion is up, people create buy orders with the sole purpose to counter a suggestion. THESE and specificly these buy orders ONLY are structurally ignored for suggestion purposes!. Most of the time, these buy orders disappear after a few days (as the creators fear they may actually buy one). In other cases, they actually buy one or more, providing more data points at that value, making it fall under category 2 (displayed above)

These 3 categories typically form exceptions to the buy orders counter argument.
