Is there anywhere to read up on what the different returns of market data from ESI give.

Eg.. how long does the history endpoint show data for?

What is adjusted price and average price? I assume that shows entire universe as it doesn't ask to define a region.

And how often does the order endpoint update?

Thanks in advance.

The closest I'm aware of is here: http://eveonline-third-party-documentation.readthedocs.io/en/latest/crest/eve/eve_market.html

Yes it's CREST, but it's the same data.

Back to the start of the previous calendar year AFAIK.

I asked this recently but wasn't given a consistent answer. It does indeed show the entire universe but may only be public markets. Do you need to know what these are? Or do you need to know what they are used for? Average price is used for certain important industry calculations.

Every five minutes, which also happens to be the cache timer.
