The shape
The range, the break, the retest
Two candles set the range. Price breaks out, comes back to the edge, and moves on.
How to read it
01
Let the range finish
The range is not set until the first 30 minutes are over.
02
Wait for a close outside
Many breaks reverse inside a candle. A close outside the range is a clearer signal.
03
Retests are common
Price often returns to the range edge after the break.
04
Size matters
A very wide range leaves less room. A narrow one often precedes a larger move.
Common mistakes
Trading the range before it forms
A range from the first ten minutes is not the opening range.
Ignoring the news calendar
A data release minutes after the open can override the range entirely.
Using the wrong clock
London opens at 8:00 London time and New York at 9:30 New York time. Both move with daylight saving.
