Plotting Ask Prices from Close and Spread Data

Summary

This brief indicator note explains how to construct an Ask-price line for a chart. It defines the plotted value as the bar’s Close price plus the spread value supplied to the calculation routine. The example identifies the calculation inputs, including price series and a spread array, but does not provide a full indicator implementation or discuss display settings.

The idea is useful for understanding how spread data can be incorporated into chart visualization, especially when comparing price series that otherwise show only closing prices. The note offers no trading rule, performance evidence, or guidance on how spread values are recorded, scaled, or handled when unavailable. It is therefore a narrow implementation concept rather than a tested trading method.

Key ideas

• The Ask line is calculated by adding the spread value to the Close price.
• The spread is obtained from the calculation routine’s input array.
• The note describes chart construction and provides no evidence of trading performance.
