Fibonacci Extension study version 1.1
Made some modifications to BLT's Fib Choices code to suit my needs, sectionalized the code for easier future code maintenance, marked the High/Low from which calculations were made, and color coded upper/lower extensions for easier visualization. Kudos for some really great ideas there @BLT Anyone that uses this code, just remember that this is designed for an intraday chart

Hi Team,
I have code Fibonacci retracement but looking if we have any code for extension for possible stock up.

Is it possible to get Fibonacci Extensions Draw Automatically using recent swing high and lows ?
The yellow straight fib lines on the top chart are the Fibonacci extensions I drew manually using drawing tool on TOS

Hi Team,
I have code Fibonacci retracement but looking if we have any code for extension for possible stock up.

Here is a zigzag script that I did year's ago that included fib extensions. You have many options in the script, including how many fib extensions to show. As the zigzag does repaint, this script currently is set to show the last 2 extensions. The picture includes an overlay of the TOS built-in fib extension tool shown with the values on the left of the last extension to confirm those drawn by the script shown on the right side bubbles.

@SleepyZ Getting this error while trying to save it as a Study? "rec data = CompoundValue(.... Identifier Already used: data at 232.5. Already assigned: data at 232.5

@SleepyZ Can you share the TOS link?

@SleepyZ I just imported the indicator. So, for ROKU it is showing as Confirmed Zigzag -36.79 on the Weekly chart. Does this indicate that the price of ROKU can drop -36.79 in a Weekly timeframe? Am I reading this correctly?

It shows that the current 'red' zigzag has fallen by \$36.79 and at that time that confirmed the zigzag. However, since the zigzag is a 'repainting' indicator, it can change direction, in this case back up before a new zigzag is formed and the current one could become unconfirmed. You have to be very careful using a zigzag. I use them mainly for support/resistance.

The next fib of importance shown is the -61.8% level and a possible target.

Here is a zigzag script that I did year's ago that included fib extensions. You have many options in the script, including how many fib extensions to show. As the zigzag does repaint, this script currently is set to show the last 2 extensions. The picture includes an overlay of the TOS built-in fib extension tool shown with the values on the left of the last extension to confirm those drawn by the script shown on the right side bubbles.
Thanks Sleepyz, What does Label "unconfirmed zigzag: 0.11" means, thanks,

was wonder if anyone has come up with a auto fib extension yet

Hello & Welcome George1 See post#10

My apologies if this is a simple question, I for the life at the moment cannot figure out what I am doing wrong. In the image linked, I removed the plots for everything except fib extension but the same happens in the original script.
The extensions (in green dash) start up from the orange arrow.

I want them to start at the purple arrow and then they would draw roughly where the lines are. I am not looking for adjust the color or the dash. I am looking to adjust the starting point to use the extensions to plot upward from the highest value on chart.

Thank you for any help or suggestions

Unfortunately, this is all that is available at this time

@SleepyZ I draw the below fib extensions manually based on the first 3 minute candle. Is it possible to automate this?

Fibonacci Extension study version 1.1
Made some modifications to BLT's Fib Choices code to suit my needs, sectionalized the code for easier future code maintenance, marked the High/Low from which calculations were made, and color coded upper/lower extensions for easier visualization. Kudos for some really great ideas there @BLT Anyone that uses this code, just remember that this is designed for an intraday chart

Hi, I want to see if someone has an auto fib just like this one but I only need it to show the 50% and 61.8%, or if someone can adjust this one. unfortunately, I know very little about how to adjust and or use thinkscripts
