QUANTCONNECT COMMUNITY
I feel like this may be a dumb question as it seems basic...
I am linking my IB account to my QC algo and my IB account already has several positions in it.
I wanted to ask how I can loop through all the existing positions in the code
Something like
Share New Research 
foreach (stock in Portfolio){
debug(stock.AveragePrice.ToString());
}But obviously, the code above does not work and I was wondering what modification I need to make.
Thanks a lot!

What will work for sure is:
Securities class has the securty collection which you subscribed to + you automatically subsrcibe to securities in your portfolio(holdings).
so list of Symbols(class) from securites: var x = Securities.Keys.ToList(); <- list of symbol class
Loop through the symbols and check (from documentation): Portfolio[symbol].Invested
if you are invested.
same way over SubscriptionManager.Subscriptions is possible
API tab in the LAB does not show that information i think ->

The Portfolio property is a collection of SecurityHolding objects to provide easy access to the holding properties. The Portfolio class is a Dictionary<Symbol, SecurityHolding> so can be accessed via ticker index: Portfolio["IBM"].IsLong. (for more datails, checkout the docs).
In order to get all existing open positions, you can use this code snippet:
foreach (var kvp in Portfolio) { if (kvp.Value.Invested) { Log($"Symbol: {kvp.Key} -> Price: {kvp.Value.AveragePrice}"); } }Michael Manus
Thanks much better
btw kvp.Value.Symbol you get the symbol
Alexandre Catarino
Yes, we can also use kvp.Value.Symbol. Ideally, we should create variables with meaningful names:
foreach (var kvp in Portfolio) { var holdings = kvp.Value; var symbol = holdings.Symbol; // or kvp.Key; if (holdings.Invested) { Log($"Symbol: {symbol} -> Price: {holdings.AveragePrice}"); } }Also note that is a "best practice" to loop through Portfolio than Portfolio.Values.

Hi,Â
just moved to QuantConnect from Quantopian, so this is very new to me. I´ve tried to find out how to view the current positions in my portfolio at a given time and i found this thread and I´m wondering: Where in the algorithm do you paste the code to see positions in the porfolio? Any help would be much appreciated :-)Â
Â
I´ve attached the algorithm which I´ve been playing around with for the last couple of days.Â

Hi Jonas,
We can access the `Portfolio` anywhere we have a reference to the QCAlgorithm object because `Portfolio` is a member of that class.
Refer to the Quantopian Migration and the Securities and Portfolio docs. The attached backtest provides an example.
Best,
Derek Melchin

Hello! Thank you so much for helpful response. This helps a lot. I also found some help from this thread where tickers and quantity can be found in the console using self.Debug:Â
