Bill Williams Fractal strategy

[Dennis W]

Newbie here looking for help in creating a simple autotrading fractal strategy using the BWFractal indicator. I want to be buying 1 tick above the upper fractal or selling 1 tick below the lower fractal. A fractal is only confirmed if two bars have printed after the fractal, so I would need the strategy to execute after the print of the second bar. Never worked with creating a strategy in NT so I am flying blind here.

Hello Dennis W,

Thank you for your note.

If you are using the indicator BWFractal from the publicly available NT User apps section of the NinjaTrader Ecosystem then yes it can be used in the Strategy Builder to create a simple strategy.

The indicator does not provide the "pivot" until the 3rd bar after the actual pivot. This is because the logic of the indicator requires that the point be higher than the previous 2 bars and higher than the next two bars.

You can create a condition that checks to see if the BWFractal upper 3 bars ago is greater than 0 which will only be true when 3 bars ago a point was plotted.

I've attached a screenshot that shows a 1-minute chart with the indicator applied. In the chart, the indicator has marked the upper with the green squares. On the right is the strategy builder condition to check if 3 bars ago the upper plot was greater than 0 and if so to then draw a red diamond 3 bars ago 3 ticks above the bar. As you can see the strategy is confirming where the pivots are which means the condition is correct.

If you're unfamiliar with creating NinjaScript strategies, we do have some resources to help you get started. All links below are publicly available.

The best way to begin learning NinjaScript is to use the Strategy Builder. With the Strategy Builder you can setup conditions and variables and then see the generated code in the NinjaScript Editor by clicking the View Code button.

I'm also providing a link to a pre-recorded set of videos 'Strategy Builder 301' and 'NinjaScript Editor 401' for you to view at your own convenience.

NinjaScript Editor 401

If you are new to C#, to get a basic foundation for the concepts and syntax used in NinjaScript I would recommend this section of articles in our NT7 help guide first:

Basic Programming Concepts
For general C# education I have personally found Dot Net Perls to be a great reference site with easy to understand examples.

We also have great resources in relation to Strategy Development on our Support Forum. There is a very active developer community in our support forum that supplements the responses provided by NinjaTrader support staff providing all users with an exceptional support experience.

Take me to your support forum!

There are a few Sample Automated Strategies which come pre-configured in NinjaTrader that you can use as a starting point. These are found under New -> NinjaScript Editor -> Strategy. You will see locked strategies where you can see the details of the code, but you will not be able to edit (you can though always create copies you can later edit via right click > Save as)

We also have some Reference samples online as well as ‘Tips and Tricks’ for both indicators and strategies:

These samples can be downloaded, installed and modified from NinjaTrader and hopefully serve as a good base for your custom works.

Further, the following link is to our help guide with an alphabetical reference list to all supported methods, properties, and objects that are used in NinjaScript.

Hi Kate, thanks for the info. Could you please send that list of professional NinjaScript Consultants or Educators that you mentioned? I think I will need help with this even though it is a very simple strategy. Thank you.
