Squaring price and Time

Gann had methods to Square price and time from Tops, Bottoms Zero points and Ranges.

Set out below will be 4 charts showing some issue in writing Bullscript to get Gann Square indicator to work for these options. Lastly I will post code similar to the previous indicator but can be applied to produce Squares for any of the above methods.

Some pitfalls in apply the indicator and distinguishing between a calendar day and a trading day calculation are shown.

The examples below are for the DJIA around the time of the 1929 Crash discussed briefly in Gann's 1935 Course "The Basis of my Trading Method".
