Security marked as non-tradable by Marcus Weidner

This error in the console while backtesting is driving me batty! I get quite a few of the following errors in the console when I backtest:

Backtest Handled Error: The security with symbol 'NWSA T3MO1488O0H1' is marked as non-tradable.

I have the following block in my portfolio code to try and handle it right when it creates the target to hand off to execute:

if (algorithm.Securities[insight.Symbol].IsTradable) {

    Decimal numberOfShares = algorithm.CalculateOrderQuantity(insight.Symbol, .10m);

    targets.Add(new PortfolioTarget(insight.Symbol, numberOfShares));

}

What am I missing? I am checking literally as I am making the trade, I looked at the open source code and it looks like I am using the same check that is used a bit down the line to throw the error.

I too have this problem (in C#). I have seen it mentioned in several threads, but have not seen a solution. My message is, for example:

Backtest Handled Error: The security with symbol 'BA R735QTJ8XC9X' is marked as non-tradable. Is there a resolution, or a know common coding error that is made that causes this condition? Please note other securities are trading just fine and the securities marked as non-tradeable change as the universe changes. Additionally, other stocks selected by the universe do trade. I cannot share my current version of my project.

Its likely been delisted but hard to say without a case to reproduce the issue. Please post a new thread so we can assist.
