Mql5官网 Fibo Levels Multicurrency 外汇EA

Description 

Fibo Levels is a color multicurrency/multi-symbol indicator that automatically plots Fibonacci levels on a candlestick chart in a separate window below the chart of the main financial instrument.

It can be used with any broker, regardless of the name of a financial instrument used because the symbol name must be entered manually as an input parameter. If you enter a non-existent or invalid name of a financial instrument, you will receive an error message saying that the specified financial instrument is unknown (does not exist). 

You can set the number of candlesticks to be displayed, as well as a bullish and bearish color. 

The indicator calculates and plots Fibonacci levels over a certain interval of user-specified bars.

The user can display Fibonacci levels of the bullish and bearish trends in different colors.

Furthermore, the indicator may be set to display the time remaining until the completion of the current bar in <d:h:m:s format, as well as Fibonacci retracements, where:

• < – an indication of the current bar.
• d – days.
• h – hours.
• m – minutes.
• s – seconds. 

Purpose

The indicator can serve as a tool for intermarket analysis visualization (convergence and/or divergence). 

Furthermore, it can be used for manual or automated trading as part of an Expert Advisor. For automated trading, use the indicator buffer of double type: 

1. Fibonacci retracement of the bullish trend – buffer 4, must not be equal to -1.
2. Fibonacci retracement of the bearish trend – buffer 5, must not be equal to -1.
