Hello and thanks in advance. I have a stratigy that is using TQQQ open and close bar minute data. The algo works well other than about 3 times a year , on average, over the last 5 years, there is an error in the back test because there isn't open bar data on a certain minute of the day. Is there a way to just skip the minute if the open bar data isn't there? or can this data be updated so this doesn't happen?
Thanks again!

I think you could use the if statement below in the onData() method. Symbol being the equity you have in your script.
if data.ContainsKey("symbol"):
or if it is specifically the open of the bar you want to check you could use
if is not none data["symbol"].Open:
