Finding minimum tick size of an instrument

Hi guys, again struggling to find this in Python documenataton. I found some references to C# and tried to improvise but not working.

I'd like to find minimum tick size iof an instrument eg "SPY"

I had some Python code like this;

# Symbol properties..

from QuantConnect import Securities

        self.sym="SPY"

         ...

        self.p = Securities[self.sym].SymbolProperties

        tickSize = self.p.MinimumPriceVariation

But I get a runtime error, would anyone be able to provide some code to help me? Thank-you very much

Update Backtest








We could get the minimum price variation with the following code:

# In Initialize
self.spy = self.AddEquity("SPY", Resolution.Daily)
tick = self.spy.SymbolProperties.MinimumPriceVariation
self.Log(str(tick))
