Quote from cornixforex:
Regarding CME it's likely 50MM worth of notional, equivalent to 400 cars offered. Most of the time there's at least 100+ not further than 1 pip from the market, but experienced people say 50/60% of that is algos so they are pulled if market moves towards them, which means you better cut your realistic 6E liquidity expectations by about half. Still HFT contributed quite nicely to FX liquidity during last couple of years which is a very good news for us traders unless we try to compete with HFT algos in their own game.
yes, 50 million notional , that's what I meant
