Kill Zones

The Kill Zones indicator highlights specific trading sessions and high-volatility "kill zone" periods on the chart to help traders identify optimal times for market activity.

Usage

The Usage section focuses on visual identification of market sessions. The indicator highlights the New York, Tokyo, and London sessions using background colors, with specific darker highlights for the "Kill Zones"—the opening minutes of these sessions where volatility typically spikes.

Traders can use these highlighted areas to:

• Identify session opens for potential breakout strategies.
• Observe price action during specific regional market hours.
• Filter trades based on whether a major global exchange is active.

Details

The script utilizes the time() function to check if the current bar falls within predefined UTC-based session ranges. It distinguishes between the full session duration and a specific 10-minute "Kill Zone" window at the start of each session. The visual output uses bgcolor with varying transparency levels: a more opaque color for the Kill Zone open and a more transparent shade for the remainder of the session.

The default time ranges (UTC) used are:

• New York: 08:00–17:00 (Kill Zone: 08:00–08:10)
• Tokyo: 19:00–04:00 (Kill Zone: 19:00–19:10)
• London: 03:00–12:00 (Kill Zone: 03:00–03:10)

FAQ

How do I change the session hours?

To adjust the session hours to match a specific timezone or different market hours, you must modify the time strings within the script's timeinrange function calls in the source code.

Does this indicator work on all timeframes?

The indicator is best viewed on intraday timeframes (e.g., 1m, 5m, 15m, 1h). On higher timeframes like Daily, the session highlights will occupy the entire bar or may not appear clearly.

How can I access the Kill Zones tool?

You can get access on the LuxAlgo Library for charting platforms like TradingView, MetaTrader (MT4/MT5), and NinjaTrader for free.
