iSpread: Visualizing Bar Spreads and Period Lows

Summary

iSpread is a chart indicator that displays the spread for each bar as a histogram, marks the minimum spread over a chosen period with a horizontal line, and shows the current spread in the indicator window. These elements provide a visual summary of spread variation over time and can help traders inspect trading costs or market conditions across bars.

The description cautions that historical-data storage affects how the indicator represents spread: it shows the maximum spread recorded during each bar interval. That distinction matters when interpreting the histogram, since the displayed bar value may not represent the spread at the close or an average spread. The document describes the indicator’s display but provides no calculation details, strategy rules, or evidence that using it improves execution or returns.

Key ideas

• The indicator plots each bar’s spread as a histogram.
• A horizontal line marks the minimum spread over a specified period.
• The current spread is displayed in the indicator window.
• Historical values represent the maximum spread during each bar interval because of data-storage constraints.
• The description provides no trading rules or performance evaluation.
