I often like to the see the price history of the cards in my collection, especially when one dramitically changes.
I use the site https://www.mtgstocks.com/ to see the history of the card and would like to be able to click on a card in my inventory and then click on the link to MTGStocks, similar to how it is done for TCG Player prices.

I am not tied specifically to MTGStocks but that is the only service that I am aware of that provides this information in an easily digestible way. If there are others that are better, that would work for me as well.

Im not sure how this would work, but I would love to see it too. Ideally I would like to be able to see cards trending up in particular.

integration with other platforms like stocks would be great! Maybe they could link back to deckbox with data like # copies sought / #copies for trade. This could encourage users of their site to register for DB and get more traders on the platform.
