Previous Day High and Low Indicator

PDHL – Previous Day High/Low Indicator for MetaTrader 5

PDHL is a lightweight MetaTrader 5 indicator that automatically plots the previous trading day’s High and Low directly on your chart.

Previous Day High and Previous Day Low are widely used intraday reference levels, helping traders identify potential support, resistance, liquidity and breakout areas across lower timeframes such as M5, M15 and H1.

Key Features

• Automatic Previous Day Levels: Displays the completed D1 High and Low on your active chart.
• Designed for Intraday Trading: Provides clear daily reference levels on lower timeframes including M5, M15 and H1.
• Automatic Daily Updates: Detects the start of a new trading day and refreshes the plotted levels.
• Stable, Anti-Flicker Display: Updates existing chart objects rather than repeatedly deleting and recreating them.
• Customisable Appearance: Select separate colours for the Previous Day High and Low lines.
• Adjustable Line Thickness: Set line width from 1 to 5 to suit your chart layout.
• Safe Object Handling: Uses a dedicated PDHL_ object namespace to avoid interfering with unrelated chart objects.
• Data Validation: Checks that daily history is available before drawing levels and reports actionable errors where needed.

How It Works

PDHL retrieves the previous completed Daily candle’s High and Low values, then draws them as horizontal lines on the current chart. The indicator continuously monitors for a new daily session and updates the levels when required.

Its efficient object-management approach keeps the display stable during ticks and data refreshes, avoiding unnecessary visual blinking.

Inputs

• HighLineColor: Colour of the Previous Day High line.
• LowLineColor: Colour of the Previous Day Low line.
• LineThickness: Width of both plotted lines, from 1 to 5.

Ideal For

• Intraday support and resistance analysis
• Daily-range and breakout trading workflows
• Liquidity and stop-run context
• Price-action trading around prior-day extremes
• Clean multi-timeframe chart analysis
