I was trying to get basis, contract month and last values for SOYBCHSSVG-C1 . Since I learned that getting history not possible with python I switched to .NET.
Here most of the examples show how to get the open, close, high and low with examples like
foreach (IBarData bar in chunk.Records.ToBarRecords())
if (bar.Open.HasValue && bar.High.HasValue && bar.Low.HasValue && bar.Close.HasValue && bar.Timestamp.HasValue)
it will be great if anyone can give some examples of how to deal with the basis, contract month and last values
