After using signal #7, which signal #18 or #19 should the referee use when reporting an encroachment penalty by team “A” and when kick off team crossed line before kicked?

CANADIAN MECHANIC:

Twice is usually fine.

Encroachment is offside, so hands on hips.

Speaking of signals.
Does anyone NOT cross their arms when signalling incomplete or no good such as on a field goal?
I have see some give the illegal shift signal in those situations where no shift was involved.

A lot fof the NCAA officials I have observed have gone away from the incomplete signal as we've known it. It now looks like a "high" safe sign from baseball.

Illegal shift signal has the arms parallel to the ground.
