I see that work is underway to optimize the market.
Not long ago, listed/canceled lots were removed from the history
https://psteamcommunity.yuanyoumao.com/market/myhistory
and now it is impossible to determine a new asset_id after removing a lot from sale

It would be good to make a parameter for the GET request (event_type=2 is needed)

Or maybe someone will suggest another way to compare skins by sales history?
