Hi Ricardo:

Where the variable n comes from in: n_z = valuewhen(sz, n, 0) as I dont see it been declared.
Thanks.

Request:

Ability to only show the most recent fan. For example, if I set the time frame of the indicator to 1 hour, it would be great it only the current fan that is currently being drawn is shown. Having the option to choose this in the settings would be really great, if possible, and if you are willing! Thanks.

Interesting projection approach, I'm currently studying lot's of Gann research. If you'r interesting here are some interesting readings:

Is it possible to add an alert for when a new fan starts?

And I am guessing the number of times that it repaints will depend on the market itself, but will be interesting to see how often it really does repaint, or if it can handle fluctuations without repainting immediately.
