Every reversal leaves the same footprint.

Price closes back through the candles that were delivering, and delivery changes hands.

That is the CISD. Everybody can draw it.

The second half is where the work is.

Once delivery flips, how far does it run before it runs out of road.

Standard deviations answer that, but only if you measure from the right place.

The same move measured from the open, from the swing pair, or from the breaker gives you three different maps.

So the anchor is the whole job. This picks it, keeps it current, and re measures the projection while the move is still alive.

And it separates two things most tools confuse: a structure that was wrong, and a structure that finished.

The CISD tells you direction changed. The projection tells you when to stop expecting more.
