A market can be informative before it is actionable

A market moves sharply and the chart starts explaining itself. That move is information, but it is not automatically a trade instruction.

First ask what you observed. Then ask what mechanism could have caused it, and whether that mechanism is still available at a price you can execute.

Write the observation without a motive

Record the time, side, size, spread, and rule state before assigning a reason. A move tells you that orders changed; it does not identify the person, source, or intention behind them.

Keeping the observation plain makes it easier to test several explanations instead of defending the first one.

List competing causes

Check for a new source release, a deadline, a liquidity change, a technical correction, or an unrelated market move. Each explanation implies a different next check.

If the cause is unclear, lower the size of the conclusion. Uncertainty about the mechanism is part of the evidence.

Define the action condition

State what would make the move actionable: a confirmed source, a defined price, enough size, or a rule that still matches the thesis. If that condition is absent, the right response may be to watch rather than enter.

The useful question is not whether the market move looks meaningful. It is whether you understand the signal well enough to act on the executable market in front of you.
