Heikin Ashi Objects (High-Fidelity)

1. Summary (Introduction)

The Chart_HeikinAshi_Objects is a specialized version of the Heikin Ashi indicator designed for traders who demand maximum visual clarity and sharpness.

Standard MetaTrader 5 indicators use a rendering engine (Blend2D) that can sometimes blur the edges of candles, especially on high-resolution screens or with specific settings. This indicator bypasses the standard rendering engine by drawing each Heikin Ashi candle using precise graphical objects (OBJ_TREND).

The result is a crisp, pixel-perfect chart representation with fully customizable line widths, immune to the blurring effects of the platform's graphics smoothing.

2. Features and Logic

• Object-Based Rendering: Instead of using indicator buffers (DRAW_CANDLES), this tool draws each candle body and wick as a separate graphical object. This ensures sharp edges and distinct colors.
• Customizable Widths: You can independently set the pixel width for the candle Body and the Wick. This allows for better visibility on 4K monitors or specific zoom levels.
• Performance Optimization: Drawing thousands of objects can be resource-intensive. To maintain high performance, the indicator includes a Max History parameter, limiting the drawing to the most recent bars (e.g., the last 500).

3. Parameters

• InpMaxHistory: The number of recent bars to draw.
  • Default: 500.
  • Recommendation: Keep this value reasonably low (300-1000) to ensure the chart remains responsive. Drawing objects for the entire history (e.g., 100,000 bars) is not recommended.
• InpBodyWidth: The width of the candle body in pixels.
  • Default: 3.
  • Increase this value if you use high zoom levels or high-DPI screens.
• InpWickWidth: The width of the candle wick in pixels.
  • Default: 1.

4. Usage

Use this indicator as a direct replacement for the standard Chart_HeikinAshi if you find the standard rendering too blurry or indistinct.

1. Attach the indicator to the chart.
2. Adjust the Body Width until the candles look substantial enough for your screen resolution.
3. Ensure Max History covers your active analysis window (e.g., 500 bars is usually enough for intraday trading).

Note: Since this indicator uses objects, you can click on individual candles to see their properties, although they are set to non-selectable by default to avoid interfering with chart navigation.
