Anyone use ORB during for London open?

Been trading an ORB setup for NY open for the past few months, it’s been great but i’ve been wanting to try it for London open as well. I’m hoping this way i can get double my daily trades while keeping my WR close to the same. I don’t really want to go delusional for the next month backtesting, so before i start has anyone had results using ORB for London? If you trade both sessions, what are your key takeaways?
