Update: Steem-engine.rocks is way, way better: See this post for details.
I read that some folks want a history of steem engine token transfers and market trades. Although I looked recently, and it appears that the full history for token transfers are already available on https://steem-engine.com.
I'm not proud of this, because it's pretty rudimentary, but I figured I'll just throw this out there:

Token transfers:
And then when you scroll down past those (or ctrl+f for it), the market actions:
At some point I'd throw in filtering on the tables and such, but I figure I would probably just copy paste them into a spreadsheet anyway and do whatever filtering and aggregation I need with it.
This works by crawling the entire account history and assuming particular json formats when extracting the data. However, there's something a little weird about it. For example, I see buy / sell / cancel as actions, where I've filtered out the cancels, and I suspect what's shown are just order placements, and not whether or not they have been filled or not. So this probably is of limited use :). I should probably put cancels back, but they have IDs attached to them that I wouldn't be able to pinpoint without cross-referencing with another source (probably the contract owner for the market?)
Anyway, figured it might be useful for somebody. Problems? Suggestions? There's a link to the github issue tracker, and you can submit changes as well if you are so inclined.
