Level 2 data question : Can it be used to gauge supply and demand on longer term charts EG: daily time frames ? or is it mainly for scalping ?
I'm curious how Level 2 data can be useful at all in day trading considering orders can be hidden/iceberg, and can be pulled instantly as well.
I've seen large size resting at a level and in instances where the size is fully absorbed I've seen support or resistance established at that level (rarely), and I've seen the level fail to hold resulting in a significant breakout of the level. More often than not the level fails to hold when the significant size is absorbed. That ("more often than not") in and of itself is an edge.
