Thanks Yogesh

I am wondering, can anyone out there write me a scan, to tell me which stock has closed above or below its most recent fractal, based on the code kindly provided by Yogesh?

Thanks again.

Hi @Nick

BW is built into the ToS Platform - no need for a custom indicator or scan.

Patterns, See below:

 

[ykd2018x]

I don't think there should be any such system or way to make such scan

so far fractals are good for below things on charts
1. creating actual and good trendlines those works
2. to see the market trend and movement
3. to understand where the buyers and sellers can be meeting together
4. to see the nature going on , on the charts and how swing highs and swing lows are so easily visible in up and down trend ,

So is there a scan for this? i've tried the built in scan, however it does not work

 

[MerryDay]

@novadolla
The author stated there was no scan and my attempts also failed

I don't think there should be any such system or way to make such scan

so far fractals are good for below things on charts

2. to see the market trend and movement
3. to understand where the buyers and sellers can be meeting together
4. to see the nature going on , on the charts and how swing highs and swing lows are so easily visible in up and down trend ,

As @diazlaz stated there is the built-in BW:

Hi @Nick

BW is built into the ToS Platform - no need for a custom indicator or scan.

Patterns, See below:

However I could only get the built-in ToS indicator to work if set to within 3 bars:

 

[greco26]

I'm currently using Bill Williams Fractal Indicator with sequence count of 4 on a 1 min chart. I was wondering if there is a scan that could be utilized to scan for the Fractal when it appears on the chart. I would like to incorporate that into a Dynamic Watchlist so that i don't have to tab through multiple charts to get the Fractal. Any help would be appreciated. Thanks

I looked into this same idea about 2 weeks ago. I was able to scan for fractals using the code. The thing to remember is that it’s delayed by the offset. What I do is add the study to the scan and set the condition as fractal down is true 2 bars ago (of your offset is 2). That works for me.

Hi Yogesh,
what script do you use for the reversal bubble shown on the chart?

 

[MerryDay]

@mrp2021 Did you know that clicking on a member's avatar will allow you to see when a member was last seen on the uTS forum? @ykd2018x has not been seen in a while.

My guess? I would say the reversal bubble was from the Reversal Indicator:
https://usethinkscript.com/threads/trend-reversal-indicator-with-signals-for-thinkorswim.183/
Please note this is a repainting indicator

Thanks i was able to get the scan to work by following your suggestions. I'm using the code in a watchlist so i can monitor a group of stocks all at once, however i'm having issues trying to assign a background color based on the upfractal and downfractal. Any suggestions on how to write that piece of code. here's what i'm using in the watchlist so far. It generates a signal which will work, it just makes it easier on the eyes to see a background color.

BillWilliamsFractalRevised1212021()."upfractal" from 2 bars ago

can you post your WL code and I will take a look at it?

This is what I'm using in the watchlist (BillWilliamsFractalRevised1212021()."upfractal" from 2 bars ago) it generates numercial values which plots the fractal from 2 bars ago on the chart. This is the code im using on the chart. Any help you can provide on the background color for the watchlist would be greatly appreciated. Thanks

This is what I'm using in the watchlist (BillWilliamsFractalRevised1212021()."upfractal" from 2 bars ago) it generates numercial values which plots the fractal from 2 bars ago on the chart. This is the code im using on the chart. Any help you can provide on the background color for the watchlist would be greatly appreciated. Thanks

Im confused on what you are looking for. You said you wanted the Watchlist background to change color but you mention numerical values being plotted on the chart. The code you posted is for the chart study and won't work in a watchlist column me for. Do you want the background to change on the chart or the WL column? If WL column, do you have working code for the WL?

 

[greco26]

Never mind. I figured out how you did it. The code below will color the words red or green. For some reason, the background color isn't working for this but not sure why. Try it on your side though as I left the code in there but commented it out. Hope this helps.

def cond1 = if WilliamsFractal()."UpFractal" from 2 bars ago is true then 1 else 0;
def cond2 = if WilliamsFractal()."DownFractal" from 2 bars ago is true then 1 else 0;

addlabel(yes, if cond1 then "UP " else if cond2 then "Down " else " ", if cond1 then color.green else if cond2 then color.red else color.black);

#assignbackgroundColor(if cond1 then color.green  else if cond2 then color.red else  color.black );

Hello local genious', seriouly you all amaze me. It makes me embarrassed to ask this benign question. I have great confusion when it comes to uparrows and downarrows with BW Fractals. It seems folks set them all kinds of different ways. They are not at all intuitive to me. Red = bullish? downarrow = same. What the heck. Help!

The wedges on the Williams fractals patters are as follows; red wedge at the low == fractal low and may reverse to the upside. Blue wedge at the high means the opposite. Hope this helps.

I am currently using the Bill Williams Fractal Indicator in a watchlist which plots the fractal two bars from the actual fractal. Is there a way to scan for a fractal upon the moment of the fractal closing bar, not two bars after. Any suggestions would be greatlyu appreciated. Thanks

No, because Bill Williams Fractal concept is a five-bar pattern. You have to wait for it to be completed to be validated.

Hi Yogesh... Hope you are still trading with the Williams Fractal Indicator. Can you please tell me how do you get your entry and profit signals on the chart above? It seems there were two signals (There are 2 stop losses). Thank you

Did you know that clicking on a member's name will allow you to see when a member was last seen on the uTS forum? @ykd2018x has not been seen in a while.

I am not sure what entry and profit signals you are asking about. The 2 stop losses were manually drawn in. They are based on the RSI oversold and overbought levels (as shown in @ykd2018x's lower RSI indicator)

The bubbles are the repainting Trend Reversal Indicator
