On market close using current daily data

Back

Is there a way to have a backtest fill orders at 4pm EST using the current daily data? I want to use the VIX index so I can't use minute data as of 3:59 or other similar tricks since it only has daily resolution. I know that this is unrealistic and that there would be implementation issues to trade this algorithm, but I would like to implement my backtest this way. Otherwise, is there a way to request the close price of the current day before the day ends (forward looking data)?Thanks.

Hi Pier-Oliver,

Since VIX data is available only at EOD midnight. There isn't any easy way to do this since Lean provides data in a way to avoid forward bias. One possible work around to access VIX data before market close is to import VIX data as custom data and set its time attribute to 4 PM. You can download VIX data from the cache and you can learn more about importing custom data in the documentation.
