The first thirty minutes are for watching, not for inventing a new range
Live session observation on Chan Road is mostly silence. The wall already holds the overnight marks. The job in the first thirty minutes is to write what those marks did, not to improve them.
Opening range talk has a useful version and a lazy version. The useful version notes the high and low of the first half hour as a later reference, after they exist. The lazy version draws a box at 09:31 because the first minute was loud, then treats the box as if it had been planned at 09:00.
Intraday support and resistance training is unkind to the lazy version. A line drawn to explain a move cannot later be called a plan. If you need a record of the opening noise, write timestamps, not architecture.
I still see notebooks where the original overnight support is lost under three extra horizontals added between 09:30 and 10:00. Those extra lines always look clever at 10:05. They look like clutter when the afternoon fails to respect any of them.
If you take nothing else from a morning in the room, take this: the first half hour is evidence gathering. The overnight sheet is the hypothesis. Mixing the two on the same pencil stroke is how traders persuade themselves they had the level all along.
