# Session & Weekly Profiles

Also known as: London/NY reversal profiles, daily bias models, weekly templates.
A Smart Money Concepts / ICT concept (Named ICT models) in the LuxAlgo Library, with 1 indicator implementation.

## What are Session & Weekly Profiles?

Session and weekly profiles are recurring templates for how a trading day or week tends to unfold against the session clock. In the ICT framework the day is partitioned into the Asian, London, and New York [trading sessions](https://www.luxalgo.com/library/concept/trading-sessions/), and a profile names a typical shape across them: in a classic bullish day, Asia consolidates, London runs the sell stops below the Asian range to put in the low of day (the [Judas swing](https://www.luxalgo.com/library/concept/judas-swing/)), and New York delivers the trend. London and New York reversal profiles invert parts of that script. Weekly profiles apply the same idea one scale up: most familiarly the template in which a bullish week forms its low early, often Monday through Wednesday, before expanding.

Profiles are the bridge between time and direction, the working material of daily-bias models. The trader first forms a bias from higher-timeframe structure and the current [draw on liquidity](https://www.luxalgo.com/library/concept/draw-on-liquidity/), then selects the profile that would deliver it: which session should produce the day's extreme, which should trend, and where [session liquidity](https://www.luxalgo.com/library/concept/session-liquidity/) should be taken before the move begins. The honest framing is that these are prototypes, not schedules. Sessions structure participation (liquidity concentrates at opens and inside [killzones](https://www.luxalgo.com/library/concept/killzones/)), which is why day shapes rhyme, but no template plays out on demand, and a day that fits no profile is itself information: stand-aside conditions rather than a broken rule.

## How to map session profiles on an intraday chart

Profiles only become useful once you can watch them form in real time, and that starts with putting the session clock on the chart.

1. Shade the Asian, London, and New York sessions on a 5–15 minute chart (New York time is the usual reference) and mark the Asian range high and low.
2. Watch the London window for a run through one side of the Asian range; a sweep that reverses quickly is the manipulation leg most bullish and bearish templates begin with.
3. Track where the day's actual extreme forms: a London low followed by expansion through New York fits the classic trend template, while New York undoing London's move fits a reversal profile.
4. Review a few weeks of days this way. Profiles are tendencies, so the goal is learning which shapes your market actually produces, not forcing every day into a template.

## How it's calculated

Session and weekly profiles are template maps of where within the trading day or week the high and low are expected to form for a given directional bias.

```
1. Split each trading day into fixed session windows: Asia session, London killzone, New York killzone, and London close, all defined in New York time.
2. Mark each window's open, high, and low as it completes, along with the running daily high and low and the weekly open.
3. Set a directional bias for the day from higher timeframe context (for example displacement toward an unfilled higher timeframe level).
4. Bullish day template: during the London killzone price protracts below the Asian range low (the Judas swing), sets the low of day, then expands higher through the New York session.
5. Bearish day template: the mirror image, with the high of day set during London and expansion lower into New York.
6. Weekly templates apply the same logic at day scale: in a bullish week look for the weekly low on Monday or Tuesday (the classic Tuesday low), then expansion into Wednesday through Friday; bearish weeks mirror with an early week high.
7. Classify each completed day or week by the template it best matched; the profile is a descriptive bias map, not a numeric indicator.

  Asia session: overnight accumulation window, commonly 20:00 to 00:00 New York time
  London killzone: commonly 02:00 to 05:00 New York time
  New York killzone: commonly 07:00 to 10:00 New York time
  London close window: commonly 10:00 to 12:00 New York time
  Asian range: the high and low set during the Asia session
  protraction (Judas swing): the false move against the bias that forms the day's extreme
  daily bias: the expected direction of the day's expansion, taken from higher timeframe structure
  weekly open: the week's opening price, used as the premium/discount reference inside the week
  weekly template: the expected weekday and session where the weekly high or low forms
```

These are discretionary templates popularized by ICT, with no single numeric output; the classification is only certain after the day or week completes.

Session boundaries vary by instrument and platform and shift with daylight saving.

Commonly cited weekly templates include the classic Tuesday low or high, the Wednesday midweek reversal, and the consolidation Thursday reversal.

## How traders use it

- To convert a bias into a plan: with a long bias, the trader expects the day's low during a specific window, waits for the stop run below the prior session's range, and only then hunts entries in the bias direction.
- To time reversals: London and New York reversal profiles say where a trend from the prior session is most likely to be cut short, so fades are taken only inside those windows instead of counter-trending all day.
- To frame the week: weekly templates set expectations for which weekday is likely to print the weekly high or low, informing whether to take a swing entry early or wait for mid-week, alongside broader [day-of-week tendencies](https://www.luxalgo.com/library/concept/day-of-week-effects/).
- To recognize no-trade days: when each session takes the previous session's extreme and reverses, the day matches the choppy [seek-and-destroy](https://www.luxalgo.com/library/concept/seek-and-destroy-profile/) shape, and most profile traders cut size or stand aside.

## Session & weekly profiles vs related timing concepts

- **Killzones** (https://www.luxalgo.com/library/concept/killzones/): Killzones are the time windows themselves, fixed slots on the session clock. A profile is the shape expected to form across those windows: which one makes the extreme, which one trends.
- **Trading Sessions** (https://www.luxalgo.com/library/concept/trading-sessions/): Sessions are the raw partition of the 24-hour day by market hours. Profiles are behavioral templates layered on that partition; they assume the session structure and add a directional script.
- **Accumulation-manipulation-distribution** (https://www.luxalgo.com/library/concept/accumulation-manipulation-distribution/): AMD, the 'power of three', is the abstract phase sequence: build, run stops, deliver. A session profile pins those phases to particular sessions, so it is AMD written onto the clock.

## FAQ

### What is a daily bias in ICT trading?

It is the directional lean for the current day (whether the trader expects price to expand higher or lower), usually formed from higher-timeframe structure, the previous day's high and low, and the nearest pool of resting liquidity. Session profiles are how a bias becomes a plan: they say which session should form the day's extreme and where entries make sense if the bias is right.

### What time do London and New York reversals usually happen?

Reversal profiles concentrate around the killzones: roughly 2:00–5:00 a.m. for London and 7:00–10:00 a.m. for New York (New York time) in the common scheme, with the London-close window near 10:00 a.m.–12:00 p.m. Those are windows where participation is deep enough to turn price, not appointments; on many days the sessions simply extend the prior trend instead of reversing it.

### Do weekly profiles like the Tuesday low of the week actually work?

The low-of-the-week-by-Tuesday idea is a template, not a statistic: there is no dependable published hit rate, and behavior varies by market and regime. Its practical value is scenario planning: it tells you where a swing entry would set up if the template is playing out, and where the read is wrong, so invalidation can be predefined instead of improvised mid-week.
