The Gann Square is one of the best known technical analysis tools created by W.D. Gann. It is considered a cornerstone of his trading technique that is based on time and price symmetry. The Gann Square is an advanced tool and using it properly requires a base level of knowledge about Gann theory and some experience with charting. Please note that the chart needs to be scaled properly to ensure the market has a square relationship. The tool uses the Gann Wheel as a basis for its patterns of price and time. It can be used in a variety of ways.
One way is to start at the previous major pivot point (normally the end of the last 5 wave sequence) and draw it so that the 1 X 1 line follows the current market support areas to a good degree. Another way is to highlight geometric formations that can forecast key support and resistance levels by counting forward from the all-time low or all-time high. TradingView has a smart tool
that allows users to draw the Gann Square on a chart.
