CBDR and Asian range boxes, CBDR deviations, London protraction markers and profile labels, with a session statistics table.
Overview
This community script follows ICT's London protraction idea for FX. It boxes the Central Bank Dealers Range (CBDR, 14:00 to 20:00 New York) and the Asian Range (20:00 to 00:00), labels their size in pips, and marks each range as valid or invalid against size limits.
It then projects CBDR standard deviations above and below, watches the protraction window (00:00 to 02:00) and the London session (02:00 to 05:00), and marks protraction highs or lows with short level lines and signal text. A statistics table counts how sessions played out, and a panel shows the timeframe and symbol.
How it works
The ideal CBDR is below 40 pips and the ideal Asian Range between 20 and 30 pips by default; ranges outside these limits are marked invalid. Up to three CBDR deviations can be drawn.
A protraction is confirmed when its extreme holds for a set number of bars (2 by default) and price closes back inside the range. Each day is assigned a profile, such as normal or negated, based on when the protraction printed.
Colors can adapt to a light or dark chart background.
How to use it
- Use the range boxes to see whether the day's setup meets the size rules.
- Some traders watch the deviation lines as possible areas for the London move to reach.
- Use the statistics table to review how often each profile appeared on past sessions.
- Compare the protraction marker time with the normal window.
These are ways some traders read it, for learning. They are not trade signals.
