I often saw that institutions run stops (Heavy vol on FP + heavy delta etc.) however I noted that only this in itself can be a fake reversal sign. I noted that when I see (in your case) buyers getting in with great activity (eating themselves through the offers even if the sellers are putting there a lot of them.)
So what I mainly ask: Do you wait as well to see some sign of the other side getting in, or you simply trade the zone (S/D) + the failure at the stops (as confirmation)?
It's all psychology...
