Quote from Martinghoul:
1. I don't know what CQG is, but I am seeing 1.5 - 2 ticks spread in US 30y during NY time.
2. The EUR/GBP mkts are closed during Asian hours. Nothing trades, so it's no wonder that you're seeing zero liquidity. It only makes sense to look at the EUR mkt between 7AM and 9PM GMT. Again, I don't know anything about CQG.
CQG is the best charting software that most professional traders in Chicago and elsewhere use, that is unless you work for a bank and get handed trades by the desks...has two different cash feed options either Brokertech (ICAP) or ESpeed (BGC). If you see Tullet or Garban that is great but not necessary to scalp futures.
