Previous Session Lines — High, Low, and 50% Levels

18 saat önce

This indicator automatically marks the previous completed session’s price range on your chart. You select a daily session window (for example: 09:30–16:00) and the script calculates:

* Previous Session High
* Previous Session Low
* Previous Session 50% (Midpoint)

When a session closes, the indicator draws all three levels on the chart and extends them forward for 24 hours, giving you clean, stable reference levels for the current trading day. Only the most recent session is shown; older sessions are automatically removed.

These levels are commonly used by day traders and swing traders to identify:

* Key support and resistance zones
* Breakout or rejection levels
* Market bias for the new session
* Areas where liquidity tends to accumulate
* Price reaction levels during overnight or intraday trading

Because the lines do not update in real time during the session, the levels remain static, accurate, and truly represent the completed session.

Settings users can adjust:

Session Settings:

* Start and end time of the session (repeats daily)
* Custom session name, which appears on the line labels

Line Appearance:

* Color
* Line thickness
* Line style (solid, dashed, dotted)

Label Appearance:

* Text size (tiny to huge)
* Text color automatically adjusts to contrast with the selected line color

Why this indicator is useful:

* Makes prior session structure immediately visible
* Helps identify high-probability reaction areas
* Shows only one session to reduce clutter
* Lines stay stable regardless of chart zoom or scaling
* Labels stay aligned at the right side of the chart
* Works on all timeframes, including extended hours and crypto charts

This tool is ideal for traders who rely on structured session analysis, including day traders, futures traders, forex traders, crypto traders, and anyone using session highs and lows to guide trading decisions.

Sürüm Notları

This indicator now includes the following improvements:

1. User-selectable session time zone
• The indicator no longer relies on the exchange’s time zone, which caused sessions to shift when changing symbols.
• Users can now choose their own session time zone from a list of common global zones.
• An optional custom UTC offset is also available for regions not in the list.

2. Tick marks at the session start and end
• A small vertical tick is placed at the start and end of each completed session.
• Tick colors automatically match the high, low, and mid lines' color settings.

3. User-defined extension beyond current price
• Users can now set how many bars the lines should extend into the future.
• The extension updates every bar, so multiple sessions using the same setting line up correctly in front of current price.
