Hi!
Does anyone know where I can find the historical data of liquidity on betfair markets over the years?
i.e.: Has there been an increase in liquidity on the horse racing markets since 2014?
       -Has there been an increase in liquidity or a decrease?
It would be nice to find some data on this topic across all sports. 
Hope you can help!
Many Thanks
