Track profit by turnover

[tryingtotrade]

Would it be possible to track profit/loss in markets by turnover of a market?
I suspect am doing worser generally in lower liquidity markets, it would be helpful to sort a profit/loss statement that only lists horse racing markets below 100k matched, between 100-200k, above 200k etc.
How would be the best way to go about it? I dont think turnover information is given on the profit/loss statement? Would anyone be able to help with it? Thank you
