The Killzone Session Indicator for cTrader automatically highlights four major ICT Killzone trading sessions—Asia, London, New York, and New York PM—directly on your chart in real time. Each session is independently configurable with customizable start and end times, colors, and toggles. The indicator visually marks session zones with optional background highlights and vertical boundary lines for clear separation. It also plots horizontal lines at each session’s high and low levels, which serve as key reference points for manipulation, reversal, and entry confirmation. Users can adjust opacity and colors per session and set a configurable lookback period to display up to 60 days of historical session zones, aiding in backtesting and analysis. The default session times are set in UTC but can be adjusted to match any broker’s server time. Compatible with all timeframes (M1 to W1) and instruments including Forex, Gold, Indices, and Crypto, this indicator supports traders employing ICT, Smart Money Concepts, order flow, and session-based strategies. It is designed for use on the cTrader platform (Windows and Mac) and coded in C# (cAlgo).
