Narrative:
I was leveling from climb at 4000 ft. Traffic inbound was showing +700 ft on TCASII then +600 ft, he should have been level at 4500 ft. Then I got a TCASII RA that said climb. I assumed he was getting a descent so I did what TCASII said and climbed. He stayed level at 4500 ft. I climbed and went over the top of him at approximately 4650 ft. I don't mind discussing this further if you would like to call me. Thank you.
