I'm having issues trying to get the price that I bought for the stock. I'm trying to use
self.Portfolio[self.syl].Price
but the price is a function that gives me the current price and not the price I bought the stock at.
I want to set a stop loss like a 10% or so. (Purchase Price * tolerance)
Is there an easy way to find the purchase price?
Thanks in advance!

Hello Michael,
For getting started with implementing machine learning, QC currently allows the use of many Python libraries (link to the full list). If you are familiar with using any of these packages/frameworks, then implementing them is as simple as assigning inputs and outputs within your algorithm. You also might be interested in reading:
https://www.quantconnect.com/docs/research/machine-learning-research#Machine-Learning-Research-Introduction
For custom indicators, you can implement them manually (e.g., initialize a rolling window in self.Initialize, fill it when data arrives in self.OnData, and then when it is full, perform an action based on some result acquired using this window of data) or by using the Indicator class to create your own.
Lastly, you can add files in QuantConnect. The caveat being, however, that a main.py file must exist as the entrypoint to your algorithm and that all project files are of .py (or .cs if using C#) extensions. If files of other types are needed, read about the object store feature.

Hi all,
Another migrant from Quantopian here. I see some familar names here as I saw them in Quantopian forum. I haven't tried to recreate my algos based on QC API yet but I will do so soon. Can anyone (we) start a forum where all of migrants from Quantopian post tutorials, trials, errors, examples of algorithms like we all did in Quantopian? So that we can speed up our migration to QC smoothly. I guess this one is a kind of doing it but we need more help, right?
Anyway, it's so painful for all of us and we need to move forward, I guess here in QC.
BTW, I heard that QC is not supporting live trading for institutions yet, is it right?
Thanks.

Hi June, I'm a quantopian migrant as well. You will find much information about converting code in this thread. -Further, per Jared in another thread somewhere, advised that they do in fact support live trading for institutions. 1) There is no limitation to the account value that your algorithm can handle, and 2) They mentioned that if you do need to set up institutional trading to contact them because they might be able do something special for you. - I recall something along the lines of cutting the cost if you have 50 or more private servers?

@Sujoy, Here at QC, there are many Quantopian migrants including me. I believe that QC people and we can help you (and all the Quantopian migrants) rebuild your (our) algos here using Python as we've been helped. First, pleae find this:
This forum is a great start and also find other forums where many Q&As were posted. And then, if you have more questions, post them, we all can help you (us). Hope this help. :)

Hello all, new here, and on the front end of the learning curve... Finally have some time on my hands to devote to grasping algo trading, and visited Quantopian only to realize they were no longer supporting live trades... Actually, QuantConnect was the first company I discovered about a year ago but at the time they didn't support Python, which is the language I'm most familiar with. Currently, I trade (manually) with RH, and contacted them regarding the timing release of their API. Vague response from them (below), but they did send a survey link to request beta access to their API. As I mentioned, I'm new, so I'll be in the tutorial section for the time being. By the time I have some chops, maybe an API will be rolling out. Good to be here!
Robinhood Response...
Thanks so much for reaching out!
We don't have a publicly available API right now, but you're welcome to fill out this survey to request to work with us as a beta partner.
We'll reach out to you directly if we'd like to work with you, and recommend you follow us on social media for any potential future announcements of a widely available API.
Let us know if you have any further questions!
Sincerely,
The Robinhood Team

Well, I guess Derek Tishler was right. After just a couple of month there are now 41,354 Quants on Quantconnect. I wish all the best to both Quantconnect and Quantopian as they have different and interesting goals and they can happily coexist. It's a pity not being able to share the technology between the two platforms though, but diversification is an asset, isn't it? ;) As a retail trader is really good to have a platform like Quantconnect designed around retail trading and being open source too, thanks for all the effort Quantoconnect. Especially thanks for:
It's time saving and a quality assurance thing the fact that we can subscribe to your platform instead of being affected by all the problems of running live trading by ourselves but it's good to know that we are not locked-in in case something goes wrong.
thanks again
