Share New Research 
Hi everyone,
I'm new and just starting out with QC algorithms. I was wondering if there are any sample algorithms (or a built in utility class) that can identify support and resistance levels given a set of bars.
Thanks in advance,
Buddhika

Hi Buddhika ! Great that you're exploring the platform. LEAN code is open source, in Github, you can run it locally from visual studio.
Lots of sample Alogorithms in the "Algorithms" folder:

Hi Buddhika,
QCU do not have examples nor a build-in class for support/resistance.
You can ask for a future implementation at Lean in Github.
Hopefully a community member has implemented it and will share.
Thanks for the replies Alexandre and Marco. I'm surprised it hasnt been implemented yet. I will request for a future implementation.
In the meantime I will try to write my own implementation since my day trading strategy relies heavily on identifying support and resistance which I would like to automate since I wont be able to watch the trades during the day. I'm a java programmer so there is a small learning curve with C#. I will share what I come up with the community.

Hey Buddhika,
I have a suggestion on how one might find supports and resistances.
We can find the local maxima/minima over a fixed look back period like 50 bars. We can identify these maxima/minima by finding the points which are either locally at the top of a "hill" or locally at the bottom of a "trough".
You can then list all these extrema points. If 2 or more of these points are within some price factor like 1%, we've found a price level.

Hi @Rahul Chowdhury, if you dont mind., could you share the same Algo in C#?
Rahul Chowdhury
Hey Saravana,
Here is the same algorithm in C#. I restructured the algorithm a bit to accomodate it to C#.

Hi Michael,
First, we need to use self.SMA instead of SimpleMovingAverage to initialize the indicator because indicators created through self.SMA are automatically updated, while custom indicators through SimpleMovingAverage either need to be registered or manually updated (docs). Then, we need to store these in a dictionary as an entry for each Symbol. Please see the attached backtest for the changes.
Best,
Shile Wen
