I understand you, my concern is this : with goatbots you can be fairly sure that the cards they are out of stock for still have the ‘correct’ buyprice; with supernova, most of the times that is not true.
Thanks for answering.

no brainer for me to follow these suggestions

Thank you! We are going to be rolling these out on a weekly basis. I feel there’s always something to talk about in the market, but their might not be great opportunities every week. I think it will be a good guide for any QS member who is interested in speculating on mtgo.

Out of comparison, here are goat’s total set prices vs nova’s vs mtgotraders from today, note, goat and nova don’t include commons and uncommons for some of the older sets, while I’m assuming mtgotraders does.

KTK: 88 vs 91 vs 95
M15: 130 vs 138 vs 157
JOU: 102 vs 109 vs 134
BNG: 67 vs 69 vs 78
THS: 101 vs 103 vs 112
M14: 70.5 vs 73 vs 85
DGM: 38 vs 35 vs 40
GTC: 57 vs 58 vs 64
RTR: 94 vs 87 vs 90

Which of these is the ‘correct’ price? I think it’s debatable and each has their own bias. I think it’s ‘ok’ to use biased data, as long as the bias is understood. The bias for supernova is that they are slow to update prices on individual cards, which means that on individual cards their prices are lagged relative to the market. But it still seems their set prices are ‘reasonable’. I’m going to continue to use supernova prices as long as they are available.

Thanks for reading and commenting, I appreciate the constructive criticism. If I can figure out a way to scrape set prices from goat, mtgolibrary or mtgotraders, it’s never a bad idea to have more data at your finger tips, but I won’t be doing it manually, which I what did today for the above numbers.

Using supernova only because they have those easy lists to get into your sheets is making your numbers unthrustworthy in my opinion. Of course it’s more work to get them elsewhere, but at least you will have the correct numbers.

Besides from that, great article ! Don’t take this as I’m not happy with it, just not with that part.

There’s very little correlation between investments you can made on MTGO and on Mtg paper.

Market dynamics, events, and prices are mostly different between the two worlds.
