Trading Sessions Indicator
Automatically visualize and analyze the world's major trading sessions directly on your charts. This tool plots fully customizable shaded blocks for the Sydney, Tokyo, London, and New York sessions, allowing you to identify liquidity ranges, accumulation zones, and periods of high volatility with total visual clarity.
Input Parameters Guide
General Session Settings
Days Ago To Draw: Sets the number of past days for which the session's rectangular zones will be projected.
Draw From: Determines the vertical range calculation mode for drawing the visual block:
OPENING_TO_CLOSING: Projects the box using the opening and closing prices within the time interval as a reference.
HIGH_TO_LOW: Projects the box encompassing the absolute high and low prices reached during the session.
Session Configuration (Sydney, Tokyo, London, New York)
Show: Enables or disables the visualization of the selected trading session on the chart.
Color: Defines the shading color to quickly identify each market.
Time Start: Defines the session's start time in HH:MM format (server time).
Time End: Defines the session's end time in HH:MM format (server time).
Visual Interpretation
The indicator draws rectangular shading in the background of the chart, respecting visual hierarchy so as not to obstruct candles or price patterns. This allows you to evaluate at a glance the range covered by each market, detect periods of highest liquidity (such as the London and New York overlap), and validate price structures relative to the previous session.
Operation Guide
Accumulation Range Identification: Use the range formed in the Asian session (Sydney and Tokyo) to define key support and resistance levels before high-impact openings.
Breakout Strategies: Identify when the price expands forcefully outside the limits marked by the previous session during the London or New York open.
Liquidity Mapping: Observe the highs and lows of each block as natural targets for liquidity sweeps.
Optimization and Recommendations
Suggested Timeframes: Intraday timeframes from M1 to H1.
Ideal Assets: Forex, Indices, Gold, and Cryptocurrencies.
Time Adjustment: Adapt the start and end time parameters according to the UTC/GMT time of your trading server.
