This is a Fibo Vector which is an auto drawn indicator showing the previous days (or week timeframe if chosen) of the various Fibonacci levels.

Anyone interest in it can google it to see the full pdf etc.
This is my summary of the indicator:

The Fibo Vector indicator automatically draws the Fibonacci retracements on their charts based on the highs and lows of the past 1440 minutes (default), which is equivalent to 1 day. This is good for the 15 minute timeframe or lower including Renko or Range bars.

If you want to trade on the 30 minute or on the 1 hour time frame, you may need to change the Draw Period to 10080 so that it will draw the Fibonacci retracements based on one week.

Fibonacci retracements are very useful in identifying support and resistance.

You will notice the red and blue areas on the chart. Those indicate the areas where the Fibonacci retracement is close to the price.

The blue diamond signals are mladen's and that indicator is attached too.
