Download m1 Data while trading

While live trading through the Mt4 bridge, and after the usual Algo/Asset loop I'd like to download the m1 data of all assets of the just closed bar.
How can I do it I have played with some updatedays/stardate but I guess I miss something.

Thank you in advance

Any Idea?

I would use a bar period of 1 minute and append at any bar for any asset the currend candle to a dataset.
