mod note:
the addorder statements were removed from this strategy as we do not post backtesting for repainting indicators
Here is an updated non-repainting version of this indicator:

The Fractal Chaos Bands Indicator was originally coded for TradingView. It helps to identify whether the stock is trending or not. Requested for conversion to ThinkorSwim by @cherif.

Here is a quick snippet of what it does and how the Chaos Bands works:

When a market is trending, the bands will have a slope and if market is not trending the bands will flatten out. As the slope of the bands decreases, it signifies that the market is choppy, insecure and variable. As the graph becomes more and more abrupt, be it going up or down, the significance is that the market becomes trendy, or stable. Fractal Chaos Bands Indicator is used similarly to other bands-indicator (Bollinger bands for instance), offering trading opportunities when price moves above or under the fractal lines.

We also added buy and sell signals into the indicator so that you can test out its potential.

Quick note: I tried to merge the other discussions posted by @WalkingBallista comments but ended up deleting all the content in that post. I do apologize.

Your guys are awesome. so fast to convert it into thinkscript.

I loaded the indicator into TOS but noticed one difference from original indicator from Tradeview. In Tradeview indicator picture, the system seemed to sell short when the price is out of upper band and to buy long when the price is out of lower band.

 

[BenTen]

@laketrader Isn't that how it's supposed so be? I didn't look too much into the TradingView version.

 

[cherif]

The rule is go long when price breaks out of upper fractal and and go short when price breaks out of the downfractal. Exits will depend on peoples risk tolerance, but the farthest u should go before exiting is when price hit the opposite fractal.

One observation as far as the upfractal and downfractal are concerned, when i move the n sequence to 3 or 4, the fractals stops to respond to price movements unless i refresh and hit apply. Any idea why?

oddly enough when I type this script into tos it does not show anything up. Any ideas why?

 

[BenTen]

@aceboogie_11 The code above is a backtesting script. You need to add it as a strategy instead of a regular indicator.

Just discovering this indicator. Very nice. Is there a way to hide the pivot candle values and display arrows/wedges instead?

How would you add alerts as the lines are crossed? I'd like to setup a johnny quotron addition with this to trigger buy / sell alarms when it crosses in either direction, then use the quotron to get the supply and demand zone ranges.

I've got a zscore strategy installed and shooting off alarms, and I have a feeling with this, it will be a two prong approach and when it hits, its gonna be amazing every single time. I've been using zscore to find bottoms. So far the zscore is always before the lift off, but I'd like to learn how to get things setup as alarms. Does anyone have any tutorials?

Fractal Alert:
Alert(UpFractal , "UpFractal ", Alert.Bar, Sound.Chimes);
Alert(DownFractal , "DownFractal ", Alert.Bar, Sound.Chimes);

I've written a version which is far simpler to read and matches the one used by Gemini (Exchange), plus I made the fractal length adjustable.

PS: It doesn't use any forward-looking code like the OP's version, so what you see is on the chart is exactly how it behaves with realtime data.
