Hi Samuel,
We recently launched a new feature to check if trade data exists in the algo. Securities may not trade every minute, or even every day, depending on their liquidity.
Previously, if you tried to access data for a security during a bar in which it didn't trade, your algorithm would receive a NoTradeDataAvailable error and stop. This was caused using "data[context.stock].price" or any other data attributes. We've now changed the behavior to log the information by default and continue the algo, rather than crashing the session.
The default is
set_nodata_policy(NoDataPolicy.LOG_ONLY)
but if you want to stop the algo if there is data missing, you can specify this in the initialize() function. set_nodata_policy(NoDataPolicy.EXCEPTION)
The LOG_ONLY setting will display this message:
"2003-02-27 handle_data:1204 ERROR No trade for V at 2003-02-27 00:00:00+00:00, skipping processing of bar and continuing"
Regarding your daily/minutely question, are you still seeing this behavior? If so, would you mind to share your algo or sample algo publically? If not, you can message me privately and I'll take a look. I unfortunately wasn't able to reproduce the issue locally.
Cheers,
Alisa
