Order Flow Fundamentals

This lesson is part of the ShaFX Academy structured learning system. Educational only — no profit promises, no signal services, no financial advice.

Aggressive vs passive participants

Order flow distinguishes who is paying the spread (aggressors taking liquidity) from who is providing it (passive limit orders). Sustained directional flow tells you which side is willing to lift the offer or hit the bid; absorption tells you the other side is large enough to soak it up.

What you can actually see

Retail platforms rarely show full Level II. What you can read is rate of change in volume relative to price movement, time-and-sales clustering, and reaction to obvious liquidity. None of this is a signal — it is context.

Common mistakes

• Reading order flow as prediction rather than confirmation.
• Assuming volume bars equal aggressive participation.
• Subscribing to paid "smart money" feeds — most are repackaged tape with marketing.
