The update for Terra is available.

Customized grid charting tool is finished. Now you can draw this charting tool clicking this button:

You can display any overlay grid, like this:

Y scale =$0.5  X scale = weekly - vertical grid lines correspond Mondays:

or this: time scale= quaters

There is a new feature there: you can mark every 10th (or any other) price bar:

Here the program displays vertical grids for 1st price bar, 11 price bar, 21 price bars ....

Using "Anchored..." options you can drag the whole grid:

Try to apply this charting tool together with quantum figures module.

Run this module (TI->Quantum Figures) and run optimization:

You see, it shows price quantum=$3.28225 time quantum=20 trading days

So we can display grid based on these quanta:

I recommend to play with these grids.

Best regards.
