Let's start a real conversation about spreading index futures intraday. My observations: NQ/ES is a spread that is incredibly useful. It can lead the ES outright. It is incredibly important for day trading. Buying NQ boosts ES and buying in ES boosts NQ. Bottom line, when cash goes into equities, it very much affects these indexes. A leading indicator for scalping outright. This spread has a BETA > 1. NQ/YM is a scalpers dream come true. Heavy institutional participation in this spread. Tilt the spread either direction or balance it. Awesome to establish a position when you are unsure of direction. YM/RTY has great and slow range. It trends and trends and trends more. Very interesting to see the action as the broad market climbs or falls. Keep an eye on this one. What do you guys think? I would love to hear your opinions on these or other index spreads.
