Narrative:

After a short sightseeing flight, I proceeded to the designated practice area south of pbi to practice some mild aerobatic figures. In the practice area I made several 90 degree turns to clear the area and make sure there were no other aircraft in the vicinity. It was a clear day. I pulled up for the second loop and coming over the top I suddenly saw another aircraft behind me. It was approximately 600-900 ft behind me. I quickly pulled out and away from the aircraft. I learned that on a clear bright day, the angle of the sun on an aircraft can make it very difficult to see. In the future I will try to be even more vigilant and also take WX conditions into more conscious consideration.

IN THE PRACTICE AREA I MADE SEVERAL 90 DEG TURNS TO CLR THE AREA AND MAKE SURE THERE WERE NO OTHER ACFT IN THE VICINITY. IT WAS A CLR DAY. I PULLED UP FOR THE SECOND LOOP AND COMING OVER THE TOP I SUDDENLY SAW ANOTHER ACFT BEHIND ME. IT WAS APPROX 600-900 FT BEHIND ME. I QUICKLY PULLED OUT AND AWAY FROM THE ACFT.
