Does a more liquid instrument exist than the EURUSD? For manual traders that focus only on one instrument, the EURO is not nearly as deep as the 3 Trillion daily turnover billed to the entire FX market: - 800 Billion EURUSD done per day - ~60% of that done during Europe&US. Break that into two regular trading sessions, at 6.5 hours each: 240 Billion turnover, per session. OR 2.4 Million standard "contracts" (aka Lots) traded, per session. What other deep markets are there?
