Impulse zone
Last opposing candle before an impulse.
After a strong impulse, the last opposing candle before it marks a zone, high to low of that candle. Price often comes back to it later.
Knowable at the close of the impulse candle. The zone ends at whichever comes first and remembers which: price came back (mitigation), or a close landed beyond the far edge (break). Those endings feed Held zone and Broken impulse zone.
