A period is simply the timeframe you trade on. If on your chart, each bar represents 1 hour of activity, then it is a 1H period. There are many periods, but the most popular are daily, 4H, 1H, 30M, 15M, 5M, and 1M.
Fib ret confluence is short for Fibonacci retracement confluence. You must understand Fibonacci and the fibonacci sequence. Then, you must understand Fib retracements,a dn only then can you understand the whole thing. I will find a good picture of Fib ret confluence somewhere and post it later.
