Gold's Sessions: each session against its usual range

429
Gold's Sessions draws gold's three sessions, Asia, London and New York, each as a shaded band from its high to its low across its hours, and around each of today's sessions a dotted frame one usual range tall, set on its open: its top half the usual over the open, its bottom half under it. A band inside its frame is a smaller session than usual; one that breaks through it, a bigger one. A label under each session and a panel set each of today's sessions against its usual: 1.52 times usual means the session ran half as far again as it usually does.

WHAT IS NEW HERE

Session tools shade the hours. This one sets each session against its own usual range on your chart, so a quiet Asia and a busy New York are each judged by their own standard, not by each other's, and it ranks today among the last 60 of its kind.

WHY GOLD'S OWN CLOCK

Gold's day runs from 18:00 to 17:00 New York, the hours of the COMEX day, and the sessions are cut on that clock: Asia from 18:00 to 03:00, London from 03:00 to 08:00, New York from 08:00 to 17:00. London's session opens with London's morning, and New York's half an hour before the US data. The marks are two hours the gold desk keeps: the LBMA gold auction at 15:00 London and New York's data hour at 08:30 New York. The auction is marked on London's clock and the data on New York's, so each one stays on its own hour in the weeks when Europe and the US change their clocks on different weekends.

HOW THE USUAL IS MEASURED

A session's range is its high minus its low. Its usual is the median range of the last 60 whole sessions of the same kind on the chart you load it on: each London against the 60 Londons before it, each New York against the 60 New Yorks before it. Whole means the session's first bar opened at its start and its last bar closed at its end, so a holiday's short session never enters the usual, and a session is never part of its own usual. The usual shows once 20 whole sessions of its kind have closed on the chart. The median keeps one wild session from dragging it.

While a session runs, it is set against its usual by now: the median range the same 60 sessions had covered by the same point of their hours, measured every 10 minutes. A session two hours old is never judged against whole sessions nine hours long. Halfway through, against the whole usual, 86 Asias in 100 on this chart read under 1 times, 82 Londons and 69 New Yorks, quiet by construction; against the usual by now, 63, 56 and 54. At 19:50 New York on 7 October, Asia had covered 13.60: 0.28 times its whole usual of 48.88, bigger than 0 of 60, but 0.85 times its usual by now of 15.98, bigger than 21 of 60.

On TVC:GOLD's 10 minute chart, 22 March to 7 October 2026: London on 6 October ran 47.18 against a usual of 30.97, 1.52 times, bigger than 54 of the 60 Londons before it. New York on 7 October ran 60.77 against 55.73, 1.09 times, bigger than 37 of 60. Once 20 whole sessions of each kind had closed, London ran past 1.5 times its usual in 17 of 122 whole sessions, New York in 15 of 118 and Asia in 9 of 121. Four New York sessions closed early for US holidays and one Asia session opened half an hour late; all five were left out of the usual. Past counts describe the past only.

THE USUAL FRAME

At each session's open its frame is set, and it never moves: its top at the open plus half the usual, its bottom at the open less half the usual. On 7 October New York opened at 4,121.56 with a usual of 55.73, so its frame ran from 4,093.69 to 4,149.42. The bottom was reached at 08:20 and the top was not. On TVC:GOLD's 10 minute chart, from 21 April, when the usual first showed, to 7 October 2026, Asia reached half its usual over its open in 48 of 121 whole sessions and under it in 58; London in 43 and 50 of 122; New York in 38 and 60 of 118. One or both were reached by 97 Asias in 121, 88 Londons in 122 and 88 New Yorks in 118, and both by 9, 5 and 10. The frame says how far a usual session travels from where it opened. It says nothing of which way.

WHAT IS DRAWN

Each session as a soft shaded band from its high to its low across its hours, the running one brighter and drawn only as far as its hours have run, so it fills its frame as the session goes. No colour says which way a session closed: the script calls no direction. Around each of today's sessions, its usual frame, dotted, from the open to the session's end: one usual range tall, half over the open and half under it. Its top and bottom stay plain until price reaches them; then the top lights blue or the bottom red from the bar that reached it, as across the range, so a session shows at a glance whether it broke its usual, which way, and when. The running session's frame is the bright one, with a caption over it, such as A USUAL NEW YORK, SET ON ITS OPEN · 55.73, and words past its end: TOP and BOTTOM until price reaches them, then REACHED and the time, such as BOTTOM · REACHED 08:20. Hover them for the price and how many of the last 60 got there. An earlier day's sessions keep their light and their labels; their frames are taken off, so nothing old reads as a level. Under each band, a label with the session's name and its range against its usual. The session still running reads against its usual by now, for example Asia at 0.85 times its usual by now. A session cut short says PART SESSION and stays out of the usual. Hover a label for the session's high and low, its range, its usual, its rank and whether the top and bottom of its frame were reached, and when. The two desk hours gold's bars run wide at, as dotted lines, each named in small words just under its bar: DATA, New York's 08:30, and LBMA PM, the 15:00 London auction. On gold's 6 minute bars from 2023 to June 2026, the 08:30 bar ran at a median 1.34 times the hour around it and the PM auction at 1.20; the morning auction (1.06) and the COMEX settle (1.10) hardly stood out, so they are left off. Three gold days are drawn by default, and older drawings are deleted as the chart moves on.

THE PANEL

GOLD'S SESSIONS and the symbol, then a row for each of today's sessions: its name and hours on your clock, the running one's name in gold; today's range (so far, while it runs); the usual; and the two set against each other with its rank among the last 60 whole sessions of its kind, such as 1.52 times, bigger than 54 of 60. While a session runs, its row reads against its usual by now: 13.60 so far, 15.98 by now, 0.85 times, bigger than 21 of 60 by now. A session that has not opened yet shows its whole usual alone, and the usual reads as a dot until 20 whole sessions have closed. The footer is the chart's key: the shading is the session so far, the dotted frame a usual range set on its open, the script calls no direction, and what the usual and by now mean.

SETTINGS

Clock (New York): New York, London or Madrid, for the hours in the panel; the sessions keep gold's New York hours. Days drawn (3): 1 to 10 gold days, today's included. Usual window (60): how many whole sessions of each kind the usual and the rank are taken from, 20 to 500. Desk hours: on or off. The Clockface marks the same hours, so turn these off if it is on the same chart. Panel: on or off.

LIMITS

Runs on intraday charts from 1 to 60 minutes that divide the hour: 1, 5, 10, 15, 30 and 60 minutes, for example. On any other chart the panel asks for one. The 08:30 mark needs a chart that divides the half hour, so a 60 minute chart shows the 15:00 auction alone. A full usual needs 60 whole sessions of history, about 8,280 bars on a 10 minute chart; with less, it uses what the chart holds, from 20 sessions (about 2,760 bars on 10 minute). On 1 and 5 minute charts the history TradingView loads can be too short for a usual. The usual by now is measured every 10 minutes, or every bar on 15 to 60 minute charts. A session cut short by a holiday shows SO FAR until the next session opens. In the weeks when Europe and the US change their clocks on different weekends, the sessions keep New York's hours, so London's session sits an hour earlier on London's own clock. Built on gold's day; on another symbol the sessions still keep gold's New York hours. The bands, labels and ranks of past sessions are fixed when each session closes; the running session moves with the price, as it should. Our own maths and code, written from scratch.
