There is already a sign for this movement in the system. Valerie may be able to find it quickly. The squeeze-open movement (closed and open o) can be arrowed to show which comes first.
 
Look at the sign for "linda" in Libras. That should have what i'm talking about.

Subject: Opening the knuckles from the hand, one finger at a time

Hello Valerie and everyone

Studying on "Opening the knuckles from the hand, one finger at a time", found the following:

"The fingers are extended, opening the hand one finger at a time, starting with the index and ending with the little finger. [...] Note: In some languages​​, opening or closing the hand one finger at a time Can start with the pinky or the index / thumb. In some cases it may be
contrastive and you will need to Specify Which finger starts the process "(Parkhurst & Parkhurst. A Cross-Linguistic guide to SignWriting®: a phonetic approach, 2008, p. 70)

In Libras has several signs that this movement begins with the pinky finger. I thought to adopt the following convention: put the symbol "Opening the knuckles from the hand, one finger at a time" near it (pinky finger) so it was clear that the movement starts for him.

See the examples:

Madrugada (Dawn)

What do you think?
