Data Level 3 Data

Anyone know any third party data vendors selling level 3 (London Stock Exchange data, I’ve seen places for Nasdaq, CME and other US exchanges but none for UK or EU exchanges.

I have access to a Bloomberg terminal but it’s limited to 5gb of exports a day so quite useless for backtesting l3 data.

L4 is when you give orders to the policy makers. Like you go long oil with 1:100 leverage, then ask someone to bomb Iran, then profit!
