Features / Session levels
Session levels
The reference prices of the sessions around the one on screen, drawn on the same chart as the dealer levels, and joined with them where they meet.
Five groups, one switch each
Open LAYERS in the chart's header. The SESSION row has five switches, all off until you turn them on, and the chart remembers your choice:
- PD: the prior day's high, low and close (PDH, PDL, PDC)
- OR: the opening range, 09:30 to 10:00 ET (ORH, ORL)
- PM: the premarket high and low, 04:00 to 09:30 ET (PMH, PML), in LIVE where the premarket is on the chart
- WEEK: the prior calendar week's high and low (PWH, PWL)
- MONTH: the month's high and low to date (MTDH, MTDL)

The prior day and the opening range
Each group has its own colour, a badge at the line's left end and a plate on the price scale. The opening range is drawn dim while it forms and holds its final values from 10:00. A price crossing a session level flashes it. The prior day's high and low are read from that session's per-second prices, the series a replay of that day draws, so a high the replay visibly reached is the high on the line.

The prior week and the month to date
The week and month lines come from the finished sessions before the day on screen; the month adds the day itself up to the cursor, so a replay draws the month as it stood at that minute. On the ES, NQ and RTY views every session level is moved by the day's basis, the same way the view moves its dealer levels.

One line per price
When a session level lands on a wall or a level of interest, they share one line, one row of badges and one plate that names every member, such as CW·C2·PDC 7620: the call wall, the second call level of interest and the prior day's close on the same strike. The strongest kind draws the line: a wall first, then a level of interest, then a session level.
