The O's stretched their winning streak to seven matches out of seven by thrashing Notts County 5-1 on Tuesday night.
They now face a televised London derby against Uwe Rosler's Bees and Slade is relishing the challenge.
"I'm just very proud of what they've done so far," he said. "We've set ourselves a very high standard that we need to maintain.
"I just feel that every game almost gets bigger. But you've got to embrace that and enjoy it and move on. We can't do any more than we're doing."
