Level indicator of Gann's Square of 9

 
I am writing notes asking me to create an indicator and then an EA on the strategy that I have been using for many years.
The problem I have to solve is this:
To display the 9-level Gann Square on the chart, I use the usual formula, but when I operate in forex as eurusd, with values around 1.xxxx, I have to use the online calculator https://www.pivottrading.co.in/forex /forexGannSquare.php which returns the precise values.
Can any friend help me figure out if the calculation is on Gann's hexagon formula or something else?

It would be of great help.
