# Fibonacci tools

Fibonacci tools help a trader to analyze trends in the price chart and predict the next price. When the price goes up, Fibonacci tools act as resistance levels, and vice-versa. In TraderEvolution platform the following tools are represented:

* Fibonacci retracement – retracement and price goals;
* Fibonacci expansion – estimating support and resistance levels;
* Fibonacci arc – places arcs with Fibonacci levels;
* Fibonacci ellipses – identifies underlying structure of price movements;
* Fibonacci spiral – places a spiral with Fibonacci levels as steps;
* Fibonacci fans – places Fibonacci angles;
* Fibonacci phi-Channel – places Fibonacci levels on a trend line;
* Fibonacci time goal analysis – places time goals;
* Fibonacci time zone – measures Fibonacci periods.
