Three levels, and most people only need two
Volume tools divide fairly cleanly into three jobs. Knowing which job a tool does saves buying two that do the same one.
Context — where is value? Volume profile shows how much traded at each price over a session or a range, which marks the levels the market spent time agreeing on and the ones it moved through quickly. Session tools and anchored VWAP give you a reference to measure the current move against.
Structure — what is happening between the levels? This is where compression, stalling and the build-up before a move show up. Price going sideways on falling volume and price going sideways on rising volume are two different situations.
Execution — who is paying, right now? Splitting volume into buying and selling aggression, level by level inside the bar, is the highest-resolution view available. It is also the one that takes the longest to learn to read.
Most traders get the majority of the benefit from the first two. The third is worth adding once you are acting on the first two consistently, and not much use before that.
- Context — volume profile, session ranges, anchored VWAP
- Structure — where participation builds or dries up between levels
- Execution — buying versus selling aggression inside the bar
