I'm trying to access the last 126 Daily bars on a Yahoo Daily dataset for 152 Symbols. Using Yahoo Data, which gives me access to the current bar's Opening price, the strategy takes ~7 minutes to execute. Creating the identical dataset with Fidelity data -- minus the current opening bar -- the strategy executes in under 7 seconds.

What am I doing wrong?

Turn off On-demand updates in the File menu.. In fact, the Y! provider tab in the Data Manager offers an option to never update on demand, which I'd recommend using.

In fact, this is a FAQ since I don't remember when:
