What London leaves New York: reading the session handover

The market does not open and close; it hands over. Sydney to Tokyo to London to New York, each session

inherits the levels, the range and the mood of the one before it. Most of the intraday structure a

beginner attributes to "market behaviour" is really the arithmetic of that handover.

The three things that get handed over

A range. Overnight, price usually compresses. The high and low of that quiet range become the

first reference levels of the day, and a break of them is the first event London can offer.

A direction. Tokyo may leave a slow drift higher. That does not mean London continues it — often

the opposite, because the move that happened without volume gets given back when volume arrives.

A level that failed. Yesterday's high, an overnight spike that was rejected, the top of the

previous session's range. These are the places where the market has already shown its hand once.

What London actually tends to do

London is where the largest share of daily volume arrives, and with it the first genuine two-way

auction of the day. Two reliable patterns are worth knowing, not because they always happen but

because they explain a lot when they do:

1. The sweep. Price takes out the overnight high or low, finds no follow-through, and reverses. The

breakout traders are the liquidity for it. This is what the liquidity sweep setup marks on a chart.

2. The expansion. Price takes out the overnight range and keeps going, and the day trends from the

open. The difference between the two is not the break, it is what happens on the retest.

The handover into New York

New York arrives at a point where London has already spent much of its move. Three shapes cover most

of it:

• Continuation. London trended; New York's data supports it; the move extends. The risk here is

entering late, at the top of a range that has already been travelled.

• Reversal. London trended into a level, New York's open re-prices it. This is the most violent of

the three, because both sides have size.

• Compression. London's move is digested in a range, and the day ends flat. Most days are this, and

most losing intraday trades happen when a trader refuses to accept it.

Planning around the handover

A short checklist before the New York open:

• Where did London leave the range? Mark the session high and low; they are the day's reference

points until one fails.

• Has the day already moved its distance? Compare the move so far with the average daily range

(ATR on a daily chart). A day that has already travelled its average is a poor candidate for a new

trend trade.

• Is there data in the first hour? If yes, assume the first move is noise and the second is

information.

• What is my invalidation? If the level that made the setup valid is gone, so is the trade.

The honest limit

Sessions are a map of liquidity, not a strategy. Knowing that London supplies most of the day's volume

tells you when the market is more likely to move; it does not tell you which way. What it does buy you

is a schedule: hours when your fills are clean, hours when a stop can slip, and hours when the

sensible decision is to do nothing at all.

Education only, never financial advice.

Frequently asked questions — What London leaves New York

Which session is best for a beginner?

The London–New York overlap, because that is where depth is greatest and fills are cleanest. It is

also the most volatile, so size matters more than timing.

Does the overnight range always get broken?

No. On many days price stays inside the Asian range for the whole session. That is information too:

a quiet London often means the day's move waits for New York, or does not happen at all.

Should I trade the session open?

The first minutes after an open are the least reliable part of it: spreads widen, the first move is

often reversed, and stops are close. Trading the second move — after a level has been tested and held

— is the more patient version of the same idea.
