History and Origins

Open - Close Box charts derive from the broader family of candlestick charts, which originated in Japan over 200 years ago. While traditional candlestick charts were designed to provide a comprehensive view of price movements, Open - Close Box charts simplify this view by eliminating the wicks and focusing on the core price movements — the opens and closes. This simplification helps traders focus on the fundamental market sentiment of opening versus closing values.

Basic Principles of Open - Close Box Charts

These charts represent price action using boxes that display the range between the opening and closing prices for a given timeframe. The absence of high and low indicators helps traders concentrate on the primary market direction and sentiment during the trading period.

• Filled Body: Indicates a period where the closing price is lower than the opening price, typically colored differently to signify a decrease in price.
• Unfilled Body: Shows a period where the closing price is higher than the opening price, typically lighter or a different color to indicate an increase in price.
