You may have heard of the term “soft hands” in reference to horse riding. I found these explanations of the terms on a forum:

“Having soft hands is all about what the horse feels
in his mouth. Being able to feel even the smallest amount of pressure
you are exerting and being able to adjust it every moment of every ride
to ensure the horse’s comfort and
responsiveness. Not being so quick with your hands that you bump him in
the mouth and having the proper timing to release the moment that they
give to pressure is also a big part of having soft hands.”
“Generally when referring to soft hands… its not about how tight you
hold the reins. But more how tight you hold the horses head with the
reins if that makes since. Being soft handed also means having quiet
hands so not bumping the horses mouth when working. Basically…. soft
handed people use very little pressure of the reins to direct the
horse.”

We should strive for soft hands in trading as well, and in all sports. To snatch and grab and hold on too tight for any outcome can spell nerves, caution and anxiety. This should never be the case when trading.
