I am looking for limit order book data for an academic paper that has a snapshot for every change in the orderbook (1st five levels are fine, but more is better) or can be built from ITCH files. Any market and geolocation work as long as the priority is price/time. The only data I found on this is the lobsterdata resource, are there other data sets (including open source) out there available for researchers?
Some vendors have academic licenses, where they offer a reduced rate or even free access to the data. You should try contact some of them like:
The Crypto space is very well feed with market data, if this suits your paper:
Binance has loads of free data.
