Fibonacci retracements is a method of technical analysis for determining support and resistance levels, based on the idea that markets will retrace a predictable portion of a move, after which they will continue to move in the original direction. They are named after their use of the Fibonacci sequence.

Used to:

1. Brokers
2. Altcoins, Bitcoin, cryptocurrency
3. Colors with indicators based on best buy/sell

Fibonacci retracement is created by taking two extreme points (start point and end point in this calculator) on a stock chart and dividing the vertical distance by the key Fibonacci ratios of 23.6%, 38.2%, 50%, 61.8%, 78.6% and 100%.

Enter the high and low price for the stock, future, currency or commodity from the previous day (or period) into the input boxes above labeled High and Low.

This is a personal project used by myself to decide when buy/sell assets on Poloniex, Binance and others.
