Fibonacci retracement is a method of technical analysis for determining support and resistance levels. The TSO Fibonacci Chains Indicator is different from a simple Fibonacci Retracements indicator in that it provides the targets for each retracement level. In other words, there is an Extension Level (D) for every Retracement Level (C). In addition, if an Extension Level is reached, then a new Fibonacci setup is created automatically. These consecutive Fibonacci setups create a chain that reveals very useful information about an asset and it helps to make better trading decisions.
