Question 1

What is order flow in trading?

Accepted Answer

Order flow is the study of the actual buying and selling hitting the market, not just the price that results from it. It looks at which side is acting more aggressively and where trades are stacking up.

Question 2

What is delta in order flow?

Accepted Answer

Delta is the difference between volume that traded into the ask (buyer initiated) and volume that traded into the bid (seller initiated) over a bar. Positive delta means aggressive buyers were more active; negative delta means aggressive sellers were.

Question 3

Does order flow predict the next move?

Accepted Answer

No. Order flow is descriptive, not predictive. It shows who was acting in the market, and it can be misread. It is context, not a signal, and nothing here is financial advice.
