One should always go for the market where the fills (liquidity) are better. Over time this adds up to a lot of $.
Ditch- I completely concur. I trade Nq exclusively throughout the day. However, I have been monitoring the YM against the movement I see in the Nq. Definitely more follow through in the YM, that you might expect to see in the Nq. However, on a day-to-day basis measuring at a ratio of 25tick YM to 100tick Nq you can scalp yourself silly fading order flow in each direction on the YM. Don't have a through understanding of market dynamics yet of the CBOT, but the guy I'm training now to daytrade perferred a smaller contract size. So, I set him up on that and he is making consistent money off the YM 1-4 contracts just doing what I describe above. Today was a perfect example of that relationship. As I look for trading opportunities somedays between the signals I get in trading the Nq, when market velocity decreases substantially. Aka every *ucking day between the hours of 9:00am-11:00am PST, some people call it lunch time, I call it Dead Market. However, as the Nq is sitting on its hands and not budging in either direction at say a double top with your Stoch/RSI maxed in overbought and higher-reference frame is creating Neg. Dvg., the happy little YM is fading the buyers back down to the mean. I've been considering trading the YM during lunch in a ultra scalp mode. 1-contract, to get realtime fill statistics accumulated. Nq's contractionary and consolidation days are cruesome to wait through. Then some dumb *ss drops his *ucking twinkie on the order entry keyboard and you get your head handed to you early in the trading day. Oh well such is daily trading life... -momo
