Yesterday's high is the most recent level everybody watched, and closing through it is the smallest unit of trend there is: one session outbidding the whole of the last one. On its own that happens constantly, which is why the volume condition carries this scan — a close above the prior high on ordinary volume is noise, on heavy volume it is intent.
