Everyone likes cheap cards, but is it really a discount? Let's find out!
Some card I picked at random: Spineback Turtle. As you can see it features a sharp discount on the per bcx side vs bcx 1. But is it really a deal? It's find out.
The price pattern is choppy over a month, and it appears barely active. By mousing over the three graphs, you can get an approximation as to what sold, at what BCX. The first image shows my cursor over the price graph. 19 days ago at 3.329.
Now, to match that up with quantity sold:
Also 19 days ago, 392. Which tells you that a card of 392 or less BCX was sold because all sales are aggregated on to one day. There's a drastic disparity in price between one bcx and multiple bcx.
Since the quantity sold graph doesn't often go above both 392 and the price above the original 3.329 We can assume that the card is highly illiquid.
To further analyze if the card is a deal or not, we can use Splintercards. https://splintercards.com/alpha-spineback-turtle
The low BCX line in the graph is mostly flat. This tells us there are hardly any eager buyers for the card. Splintercards also gives us a far longer timeframe to look over.
90 days compared to a month.
