I also ran into the the same bizarre situation today. Have you figured out something?

@Paska-Houso Many thanks! I'm still at sea with the internals of backtrader, does it provide a method to get our current holdings (i.e. a list containing all the stocks we are now holding) ?

What are the merits for one another: 'preload' and not 'preload'?

And does 'preload' have to be set as 'False' if we want bt to run in live-trading mode?

And also trades, positions. Or just it's currently impossible to get analysis for each single strategy when backtesting multiple strategies with one cerebro instance?

How do we get pnl data for each specific strategy when we have more than 1 strategy added to cerebro?

If i have multiple strategies (by 'cerebro.addstrategy(st0)' ...), how do I get perf records (pnl, trades, etc) for each strategy?
