Fifteen minutes later

The number has printed. You still do nothing for a while, and then you make one decision.

Wait fifteen to twenty minutes

After a single high impact release, give the chart fifteen to twenty minutes before you form any view.

That is roughly how long the first reaction takes to finish. Before it does, the candles are made of orders being filled fast and wide, not of anything you can read.

The first candles after a release are not information yet.

If it moved hard, the day is over

Then look at what happened. If price was thrown around, you are finished for the day, and that is the end of the decision.
