Max bid for each sell

[Eliminatos]

Hey Community!

So I have the following problem:

I have 2 tables, one containing different bids for a product, and one containing the price, date etc. to which the product was sold.

The tables look like this:

Table bids:

Bid_id	Start_time	End_time	Product_type	price
1	18.01.2020 06:00:00	18.01.2020 06:02:33	blue	5 €
2	18.01.2020 06:00:07	18.01.2020 06:00:43	blue	7 €
3	18.01.2020 06:01:10	19.01.2020 15:03:15	red	3 €
4	18.01.2020 06:02:20	18.01.2020 06:05:44	blue	6 €

Start_time and End_time define the time, on which the bid was placed/taken down.

Table sells:

Sell_id	Sell_time	Product_type	Price
1	18.06.2020 06:00:31	blue	6,50 €
2	18:06.2020 06:51:03	red	2,50 €

The sell_id and the bid_id have no relation with each other.

What I want to find out is, what is the maximum bid to the time we sold the product (how much more expensive could we sell). So if we take sell_id 1, it should check, which bids for this specific product were active during the sell_time (in this case bid_id 1 and 2) and give back the higher price (in this case bid_id 2).

So a simple IF(start_time < sell_time AND end_time > sell_time) would suffice, however I am struggling with creating an actual measure, since those 2 tables have no relation with each other.

I hope, this somehow explains my problem. I am grateful for ANY help you can provide. Thanks in advance!

@Eliminatos,

Try this measure:

Max Bid = 
VAR vProduct =
    MAX ( TableSells[Product_type] )
VAR vSellTime =
    MAX ( TableSells[Sell_time] )
VAR vTableBids =
    FILTER (
        ALL ( TableBids ),
        TableBids[Product_type] = vProduct
            && vSellTime >= TableBids[Start_time]
            && vSellTime <= TableBids[End_time]
    )
VAR vResult =
    MAXX ( vTableBids, TableBids[Price] )
RETURN
    vResult

In the sample data, I assumed the Sell_time month should be "01" instead of "06".

Wow thank you for the fast answer!

Thank you very much! This works perfectly and is way faster on big databases than other solutions i have tried!

Have a nice day!

PS: Yes, i meant sell_time month "01" 🙂
