Spread arms signal for no closely guarded? Yes or no?

[Dewey1]

I don't know about the HS mechanic but just to clarify the NCAA mechanic you do not indicate if you have not started a count. The fact you are not counting indicates they are not closely guarded. You will see people use the spread arms after they have started a count to indicate the player is no longer closely guarded. This is the proper mechanic.
