Reading Hollow Candlesticks by Open, Close, and Previous Close

Summary

The document explains how hollow or filled bodies and red or green colors encode separate comparisons in a hollow candlestick chart. A hollow body indicates that the current close is above the current open, while a filled body indicates that the close is below the open. Color compares the current close with the previous close: green marks a higher close and red a lower one. Combining these rules explains the four appearances in the question without treating color and fill as duplicate signals.

This is a chart-reading convention rather than a trading strategy or claim about predictive power. The answer gives definitions and points to charting references, but it does not evaluate whether these candle patterns forecast returns or specify how a particular platform handles unchanged prices, missing data, or other edge cases. Traders should confirm the convention used by the charting software, since candlestick coloring can vary across tools.

Key ideas

• Hollow versus filled body compares the close with the current open.
• Green versus red compares the close with the previous close.
• The two visual properties encode different price comparisons.
• The explanation defines chart notation but provides no evidence of predictive value.
• Charting software conventions should be checked for platform-specific details.
