For installation of Arcs of Fibonacci you should select the insertion menu item - "Fibonacci" - "Arcs"
For installation of arcs of Fibonacci usually take the highest and the lowest level of the Trend.
Arcs of Fibonacci are put as follows: Radius of an arc is accepted to 100%,
and then draw the curves, crossing a trend line at distance,which is equal to 38.2%, 50%, 61.8% of total length of a segment.
After that we receive lines of support and resistance - their passing by the price gives a power pulse to go forward.
But at the same time, these levels can be a serious barrier. It is necessary to track the price at the time of passing the arcs of Fibonacci.
