I was looking through the documentation and couldn't figure out what the EMA calculation period is based on. Is it based on the resolution of the underlying asset that it is tied to? For example, if SPY is minute resolution, and we define an EMA("SPY"), is it then using 8-minute lags for the calculation?

This looks great Tony, it's definitely something you would want to make available across multiple algorithms. You can create custom libraries in the Algorithm Lab and access those from different algorithms. If you look at the side-bar in the terminal, there is a section beneath the files in your current project where you can create custom libraries. Just click the "Add New Library" button! You can also see the answer to a similar question that was posted here.

You can find the EMA code here:
I found that having a look at the code is the fastest way to solve my doubts. Luckily it is open source ;)

Sorry, I see now that you were referring to the algorithm's shortcut method for the indicator.
You can find its code here:
The period is a mandatory parameter. E.g EMA(spy, 14)

I have already reviewed the documentation, but I"m not too familiar with C#, so I can't see where the units on period are in the code below. Any clarification would be of great help. Thank you. Is it minutes, hours, days? Does it depend on the underlying resolution?

Hi Fred, Thanks for the answer, this is what I was looking for. It wasn't clear from the documentation or the code. I'm not too familiar with C#, I code in python.

AlMoJo ,
Also, if you would like to explore more CBOE data sets, then you can use the Nasdaq Data Link provided below.
Correction in my last post: meant to say CBOE and not Quandl (Quandl was acquired by Nasdaq)

Spacetime,
There are only 6 trades for SHV in your version of the code.
Can you try changing in the code the VIX and VXV data retrieval in a way like in the attached sample.

Hi Vladimir,
Hmm… not entirely sure why there were only 6 trades executed.
The above backtest which I have attached was taking a “bit” to complete for me and I was engaged with other work, so I ran the above model (shaerd by pangyuteng) with a start date of self.SetStartDate(2020, 11, 1) just to speed up things.
Hmm… I have extended the date range to start from self.SetStartDate(2019, 1, 1) and it does not have too many trades either. (backtest attached)
If you have noticed from the above example shared by pangyuteng , then it does not trade that often either. [ self.SetStartDate(2019, 1, 1) ]
But, the fixes which I have shared above does work as the error which was being received by AlMoJo is no longer occurring.
Hmm… maybe someone else might have a better idea on this, but I will try to look into this further. Hmm… maybe the LSTM configuration needs to be looked into or the volatility data resolution and other resolutions needs to be changed to minute time slice if possible.

Spacetime,
I backtested cloned pangyuteng algorithm with only changes in my_custom_data
url_vix = "http://cache.quantconnect.com/alternative/cboe/vix.csv"
url_vxv = "http://cache.quantconnect.com/alternative/cboe/vix3m.csv"
It generated 13 SPY-SHY trades and metrics as your last one, but the performance is not comparable to pangyuteng's results.

Vladimir,
Hmm… If you want to compare it with pangyuteng's results, then you have to provide an end date of self.SetEndDate(2020, 1, 1) because pangyuteng's model ends around that time. Please note, pangyuteng's post is time stamped somewhere in December 2019.
Try to run it with end date parameter and check to see if performance is comparable.
I have attached a backtest run starting from self.SetStartDate(2019, 1, 1) and ending at self.SetEndDate(2020, 1, 1) and it only traded once.
Hmm…

Spacetime,
I definitely like the metrics from your last backtest, but my attempts to reproduce them for some reason were unsuccessful.

Hello everybody,
Pangyuteng this is an amazing result. Jack Simonson I also think technical indicators would help a lot.
I tested Pangyuteng version on the 2022 crash and it is not so good at dodging it. I taught maybe going hourly timeframe instead of daily could help even if I know that trading more frequently is not really good.
Anyone has an idea on how to change the timeframe? I tried to pass all the .Daily to .Hourly but obviously it wasn't that simple.
Kind Regards

Hi AlMoJo,
To change the timeframe of the entire algorithm we recommend adding the following to the Initialize method:
Note that the algorithm uses higher frequency bars to create lower-frequency bars. Therefore to use indicators or consolidators at the hourly resolution we need to have the universe at the minute, seconds, or hourly resolution.
Best,
Varad Kabade

Hey Guys and Sherry,
Thanks for this incredible thread. So many interesting ideas!
