VISA 190 when to File EOI on SkillSelect


I have recently completed my ACS assessment with a positive result for ANZSCO 261313. Since I have family in ACT and they are sponsoring me, I would like to apply for 190. For this, there are two steps

1.File EOI through SkillSelect
2.Submit Canberra Matrix

I have already submitted the canberra matrix. I would like to know as to when should I file EOI on skillSelect? Should I do it right now or should I wait for Canberra Matrix result?
