CBDR Deviations+ (M1D)
Between 2pm and 8pm New York the market trades in the hands of the dealing desks, and the range it builds in those six hours is the Central Bank Dealers Range. Its usefulness is not the range itself but what is projected from it: the height of that range, replicated outward above its high and below its low, estimates where the high or the low of the following day is likely to form.
The Central Bank Dealers Range, and the practice of projecting standard deviations from it, are concepts taught by ICT (Michael J. Huddleston). The model is his; this script is one implementation of it.
One standard deviation is the range added to the range high, and the same range subtracted from the range low. The second adds that height again to the first, and so on through the third and the fourth. Each multiple carries a different expectation, and the script names them rather than leaving four unlabelled lines to be read as equals.
This script measures the window, grades it, and projects it. It takes no directional opinion of its own — these projections locate where a high or low may form, not which of the two to expect.
THE WINDOWS
Four are available, each with its own session string, colour and size limits.
- CBDR, 2pm to 8pm New York.
- The Asian Range, 8pm to midnight, beginning as the dealers range closes.
- London, 2am to 5am.
- A free window, named by you, for any reference period you prefer.
Each window sets which calendar days it fires on, separately from its times. Any evening window that leads into the following session runs Sunday through Thursday — it carries Sunday and skips Friday, because Friday evening has no session left to feed. A window sitting inside the trading day itself runs Monday through Friday. The two are not interchangeable and choosing the wrong one throws no error, it simply drops a day, so the choice is exposed rather than buried in the session string.
Only the dealers range is drawn by default. The Asian range begins as the dealers range closes and adds little beside it, so it is switched off along with London and the free window; every window has its own toggle.
HOW THE RANGE IS MEASURED
From the candle bodies by default — the highest open-or-close to the lowest open-or-close in the window.
A wick carries the dealing spread, and no two feeds agree on where one ends. Bodies are the bulk of what actually traded, so they give a range that reproduces on someone else's chart. The wick range is still worth seeing, so the default mode draws it as a fainter box behind the body range rather than hiding it. Either can be used as the measurement basis outright.
THE DEVIATIONS
Multiples of 1, 2, 3 and 4 are drawn either side, each optional.
The first and second hold the ideal high or low of the day, and often it is only the first. The third is the outer bound most days respect. The fourth belongs to a high impact London news event, or to a session that reverses in New York. Those readings are printed alongside each line when full labelling is on.
A multiple of 2.5 is also available and is off by default. It is not part of the original set of four and is offered only because it circulates widely.
Projections appear when the window closes, not while it forms. A range that is still building has no final height, so anything projected from it would move on every candle.
THE SIZE TEST
A dealers range only carries information while it stays tight. A wide one means the desks were not holding price, and projections taken from it are unreliable.
The published limits are quoted in pips, against a daily range of roughly a hundred: about a third of the average day as the ideal ceiling, and forty percent as the point past which the range should not be used. This script applies those same ratios to the instrument's own average daily range rather than to a fixed pip figure, so the same test carries across index futures, metals and crypto instead of only foreign exchange. The ratios are ICT's; expressing them against a measured daily range is this script's own arithmetic, and both limits are adjustable. Absolute-price mode is also provided for anyone who wants the literal figure.
Every window is graded Ideal, Acceptable or Oversized, and any oversized window can be stopped from projecting while still drawing its own box — so the reason for the rejection stays visible rather than the range simply vanishing.
THE BLOCK PROJECTION
The deviations say where London's high or low is likely to form. The block projection takes the next step and estimates how far the day then runs the other way, measured from what London actually used.
London moves away from the dealers range first, against the day's real direction. Once that run is over, the script counts how many whole standard deviations it reached beyond the range. The block is the range plus every one of those deviations: a London high at +2 SD makes a block three range heights tall, a London low at -1 SD makes one two heights tall.
The block is then stacked the other way. When London made the high, it is laid on the range low and repeated downward. When London made the low, it is laid on the range high and repeated upward. Two blocks draw by default and up to four can be shown.
It is drawn to be read at a glance, each day kept inside its own window. The deviations London used sit on the range as solid boxes, the first grey and the rest in the day's colour, each one named with its size in pips. The blocks step away from the other edge as a staircase of outlined boxes, one candle further right per block. Block 1 carries its own sum written inside it, for example "= CBDR + 2 SD = 3 x 13p = 39p", and dotted lines inside every block mark each range height it is made of, so the block can be compared with the deviations by eye. A line runs out from the range to the extreme London printed, named at that candle, and the range's own name carries its size. A plain line style is still available.
A block level is a frame, not a target on its own. The projections lead to a overlap of time and price: a block that lines up with a PD array is the real target, and one that does not is just a number. Tested on its own, a bare block level is not reached more often than any other evenly spaced level would be. The PD array calls the shot; the block only says where to look for one.
- Measured from the candle bodies by default, the same as the range, with the wick range as a option or drawn alongside as dashed lines.
- The London extreme counts at 05:00 New York by default, the close of the London open kill zone, and the blocks draw then — once the move has happened, never while it forms. A run that stops just short of a deviation still counts as reaching it; how short is a setting.
- If London has not reached a whole deviation either side by the cut-off, no block is drawn: only the dealers range stays, marked "Not valid · 0 SD" above it, and the panel says London stayed inside one deviation. A range over 40 pips is marked "Not valid · over 40p" the same way. On index futures this is the usual case: London reaches a full deviation by 05:00 on roughly one day in thirteen, so the block draws far less often there than on foreign exchange.
- If both sides of the range are run past one deviation before the cut-off, the side reached first is taken as the London run. That rule, the cut-off hour and the near-miss allowance are this script's own engineering, not part of the taught model.
- The block's target lines stop at 14:00 New York, where the range of the day usually caps, and turn dotted once price has traded to them. The London close kill zone, 10:00 to noon, and the 14:00 cap can be marked as well, off by default. That clock holds on foreign exchange and gold, where 14:00 caps the day about two days in three. It does not hold on index futures, where more than half of the day's extremes print after 14:00, so on futures other than metals the 14:00 stop and its marker switch themselves off.
- The arithmetic sits in the target line's tooltip.
The block has its own size test, in pips: ideal up to 30, pushing it up to 40, and no dealers range at all past 40, in which case nothing is projected and the panel says why. On foreign exchange a pip is the quoted pip. Everywhere else one pip is read as a hundredth of the average daily range, so the same ratios carry to futures, metals and crypto. The figures are adjustable.
The panel gains three short rows for the block: the day type, the deviations London used, and the block size. While London is still running it shows the count so far. Its tooltip carries the questions to answer before any of it matters: premium or discount in the larger range, the directional bias, and a opposing higher timeframe PD array or liquidity as the target. It is not a projection to use every day.
THE LONDON PROFILE
London delivers a sell or a buy day in one of two shapes. In the normal profile price moves straight away from the 00:00 New York open and trades through the Asian range or the dealers range by about 01:30, with the high or low of the day forming in London. In the delayed profile there is no clean move by 02:00, and the entry comes from a retracement between 02:00 and 03:00 into a premium or discount PD array. The four profiles are ICT's; the bias that picks the side comes from the daily chart first, and this script does not decide it.
The panel reports the facts that tell them apart:
- ASIA: the Asian range, 20:00 to midnight New York, against the 20 to 30 pip band the normal profile wants. It is measured even when the Asian range box is switched off.
- 00-02: what price did from the 00:00 open to the 02:00 close, up, down or flat, and whether and when it traded through the Asian range or dealers range by 01:30.
- PROFILE: the shape that matches so far, for example sell normal forming, buy normal shape, or delayed: watch 02-03 retrace. When the Asian range is outside its band, it says the normal filter was not met; a dealers range over 40 pips with a tight Asian range is named as the exception.
- 02-03: on a day with no normal shape, how far price rallied and dipped from the 02:00 open.
The flat threshold (10 pips by default), the 01:30 cut-off and the Asian range band are settings, and they are this script's own engineering rather than ICT's numbers, apart from the 20 to 30 pips. Pips are read the same way as for the block: forex pips on forex, a hundredth of the average daily range elsewhere. Nothing in the panel is a signal; it describes what London has done.
WHEN A WINDOW IS ONLY PART MEASURED
Index futures are closed between 2pm and 6pm New York on a Sunday. The window that feeds Monday can therefore only ever capture the last two of its six hours on those instruments, while the foreign exchange market ICT described it on is open throughout.
The script counts the candles it actually received against the number that window should hold, and reports the range as Partial when it falls short. A two hour fragment presented as a six hour range is worse than one that says what it is.
WHAT IT DRAWS
- The range as a borderless box spanning its whole window from the first candle, its name written large and faint inside it. It appears when the window opens and grows in height with price rather than arriving finished at the close.
- A small state note above the box: forming while the window runs, and partial or oversized when that applies.
- The high and the low as solid lines inside the window, each beginning at the candle that actually made it.
- The optional equilibrium — the 50% of the range — as a dotted line. The 50% of a range is its equilibrium; consequent encroachment is the 50% of any imbalance, and the two are not interchangeable, so this level is named for what it measures.
- The deviations as dashed lines from the window's close, each named with its multiple and optionally with the expectation attached to it. For the dealers range these are off by default, because the block boxes already show the deviations that were used; switch them on under Standard Deviations.
- A small status panel at the top right: the script, instrument and timeframe, then each window's size and grade, the average daily range, and the block rows. Hovering a row shows its cap, its age in hours and how many of its levels were retired for distance.
Every coordinate is a timestamp rather than a bar index, so nothing drifts off the candles it was measured from.
Labels are transparent callouts with no backgrounds. Each window chooses its own placement — beside price at the right edge, before the line's own start, centred above the line's span, or hidden entirely — so four windows can be on at once without every caption in the script stacking into a single column. Only the right edge placement is nudged for overlap, and only when two captions would physically collide; the line itself always stays on its true price.
Line widths are set per window and separately again for that window's projections, so a reference range can carry weight while its deviations stay thin, or the reverse.
SETTINGS
- Windows: four sets of times with individual toggles, a day rule each, a colour each, and a name for the free window.
- Measurement: bodies, wicks, or bodies with the wick range drawn behind; how many windows stay on the chart; the threshold at which a window is called part measured.
- Deviations: which multiples are drawn, which windows project at all, whether both sides or only one, whether each line is annotated with its meaning, and a fixed span after which a projection stops rather than running to price.
- Size validity: percent of average daily range or absolute price, the daily range length, and the ideal ceiling and hard cap per window.
- Retirement: how many hours a window survives, and how far from price a level may sit before it is removed.
- Style: label detail and spacing; a placement per window — right edge, left of the line, centred above it, or hidden; a line width per window and a second width for that window's projections; equilibrium and box border widths; panel size; colours throughout.
NOTES
- Non-repainting. Windows are measured on confirmed candles only, and no range is revised once its window has closed.
- All times are New York and resolve through the exchange-independent New York clock, so they stay correct across daylight saving on any symbol.
- Requires a 60-minute or finer intraday chart. Anything coarser cannot resolve a six hour window into enough candles to measure it, and the panel says so rather than drawing something approximate.
- Nothing is left hanging. A window retires after a set number of hours, and any level price has walked away from is removed — the panel counts what it removed so it is never a silent disappearance.
- A window on the evening rule has a gap built into its week. There is no Friday range and no Saturday range, and Sunday's does not close until 20:00, which leaves roughly seventy-two hours where Thursday's is the newest one in existence. The default retirement carries it across that gap rather than emptying the chart from Friday evening to Sunday night, so a range three days old on a Monday morning is expected rather than stale bookkeeping. Its age is printed in hours beside it, and coloured once it is no longer same-day, because reading a carried-over window as last night's is how it gets traded by mistake. Shorten the retirement if you would rather see nothing than see something old.
- Nine alert conditions: each window closing inside its ideal ceiling, closing acceptable, or closing oversized, price reaching the second or third deviation either side, and the block projection being drawn.
- The London window and the free window apply the same arithmetic to a different period. They are conveniences rather than described concepts, and are off by default for that reason.
