Attack Hack, Speed Hack

I found out my adress for Attack % skill easy by CE.
Its 121E5D20 and works fine: always on 55%.
But now my question: how i search for the speed skill adress ?
in the skill is no value about how much % i faster than normal when its on.
i tried to search for 0 and 1 when i do the skill on and off but to much adresses after 20 times or so. can someone help me pls whats the way to find out the adress for speed walk skill to have it always on ?
the adresses in forum dont work at me. so give me no adresses pls only way to find out myself.

You should try to search unknown dword. When you activate the speed skill, unknown value will increase... then search "decreased value", "increased" and so on.

thx that helped me.
