ICT Killzones & Pivots indicator

It marks out key trading sessions (Asia, London, New York AM, NY Lunch, NY PM) by drawing:

Killzone boxes (high/low of session)

Pivot lines (session highs and lows)

Labels (like LO.H, NYAM.L, etc.)

Day/Week/Month opens and separators

Custom timestamp markers

Here’s what’s happening in the code:

🔑 Key Features:

Configurable Killzones

Asia: 20:00 – 00:00 GMT-4

London: 02:00 – 05:00 GMT-4

NY AM: 09:30 – 11:00 GMT-4

NY Lunch: 12:00 – 13:00 GMT-4

NY PM: 13:30 – 16:00 GMT-4
Each session can show:

Colored boxes (range of session)

Pivot high/low lines

Labels like AS.H, LO.L

Alerts when levels break

Drawing Limits

max_days input controls how many past sessions are shown.

Prevents chart clutter.

Opening Price Lines

You can mark important open levels: true day open (00:00), 06:00, 10:00, 14:00.

Useful for ICT concepts like “open drive.”

Day/Week/Month Opens

Option to plot open price levels with labels (D.OPEN, W.OPEN, M.OPEN).

Can also show separators for each new day/week/month.

Alerts

Triggers when session highs or lows are broken.

Example: “Broke LO.H” if London high breaks.

Custom Timezones

Killzones are adjusted using the gmt_tz setting.

Default is GMT-4 (New York).

Cutoff Time

After a set time (default 12:00), extensions of session lines stop updating.

⚡ In practice:

Boxes highlight accumulation ranges (ICT killzones).

Pivot lines help track liquidity grabs (session high/low breaks).

Labels + alerts keep you notified of important market structure events.

Combined with ICT concepts, you’d look for setups like:

London killzone sweep of Asia range.

NY session taking liquidity above London high.
