TJR Session highs and lows
Session Highs and Lows — Killzone Levels
Marks the high and low of the major trading sessions as extended horizontal
levels, plus a vertical line at a time of your choice, and clears the chart
at the start of each new day.
What it draws:
• Asian Range high/low
• London Killzone high/low
• New York AM Killzone high/low
• London Close Killzone high/low
• A vertical line at a configurable time of day
Once a session closes, its extreme is labelled and extended to the right, so
you can see which levels price is reacting to. Every session has its own
on/off switch, session times, timezone, colour and line width.
Settings worth knowing:
• Timezone per session — define each killzone in whatever timezone it
actually belongs to. Defaults are Zurich for Asia and London, New York for
the two NY sessions, so both sides stay correct across DST changes. Set any
of them to "Exchange" to follow the symbol's own timezone.
• Vertical time line — pick any hour and minute (default 15:30 Zurich, the US
cash open). It is drawn at the daily reset, so the level is already on the
chart hours before that candle exists.
• Daily reset — choose the reset time (default midnight) and how many days of
drawings to keep. 1 gives you a clean chart every morning, 2 keeps
yesterday's levels until today's replace them, 0 never deletes anything.
• Show session labels — turn the text off for a lines-only chart.
• Stop extending on mitigation — a level's line ends at the bar where price
first trades through it, instead of running on forever.
Notes:
• Intraday timeframes only. Works on any intraday resolution, including
1 minute and hourly.
• No alerts are included.
