Hi.

All I want to do is test a simple strategy where I short 10k of VXX every month forever, from 2009 until now. I tried doing this on Quantopian, but their VXX data is hosed because they don't handle the 2018 transistion to VXXB. It looks like the QuantConnect data is good though.

https://www.quantconnect.com/data/tree/equity/usa/daily/vxx.zip

However, my code gives this runtime error - Backtest Handled Error: VXX: asset price is $0. If using custom data make sure you've set the 'Value' property.

How can I fix this? Is it my code? Or the data?
