A position cannot be partial but can be splitted into integer parts.

Re: "two elementary questions". It's optimal if you ask one distinct question per topic, and don't group unrelated issues together. Name the topic(s) so as to summarize the gist of the issue rather than describe what kind of question it is in your opinion. Thanks.

1. You can any number of positions on any bar - limited only by buying power.
2. Each Position has to be managed separately.
3. Multiple positions are not automatically "merged" into one position. If you want to do that, you must exit all Positions and enter one larger position.

What's the scenario, precisely, in which it would be useful to manage 5864 positions for the same instrument?

I think you have misunderstood, I buy as an example the Spy, as capital I have 10,000 dollars available, the price stands as an example at 110 dollars, it is about the fact that the system buys only whole pieces, in this case 90.00 shares, but mathematically it would be just 90.90909 so that the entire 10,000 dollars would be invested. My question was whether it is possible to set Wealth-Lab so that it can also buy fractions?

Currently fractional shares are supported only in live trading by the Alpaca provider, but not in backtest.

See Trading Preferences > Special Order Types > Use Fractional Shares when Possible. F1 for the Help explanation.

But after checking it with Alpaca, it seems not to work there either. So, let's just say it's not supported at all at this time.
