A charting technique consisting of three curved lines that are drawn for the purpose of anticipating key support and resistance levels, and areas of ranging.
Investopedia Says:
Fibonacci arcs are created by first drawing an invisible trendline between two points (usually the high and low in a given period), and then by drawing three curves that intersect this trendline at the key Fibonacci levels of 38.2%, 50% and 61.8%. Transaction decisions are made when the price of the asset crosses through these key levels.
