Why does WTM fail the "adequate stop room" check?
The stop sits only 0.9× the average daily range (ATR) from price — inside the 1-ATR minimum, so this check fails (normal noise could hit it). It passes once there's at least 1× ATR of room.

The nearest flip level is "adequate stop room" passes on a close above $2146.02. Each price-anchored check has an exact next-close level, shown in the Flip levels panel above.
