MultiBacktest does not test all symbols

[acud]

Hi @kernc,
I've been trying to do the following: I have datasets for individual symbols (they don't all start at the same date, some have more data, some less) and I then try to run the MultiBacktest on them. The TQDM progressbar stops about quarter way with a red fill and hands me over the results.

While I give it 50 symbols with about 10 years worth of intraday data, but I get back only about 35. Any idea on why this might be? are there any assumptions made on whether the sets overlap in terms of date indexes?

Nope, I think none. Could be a multiprocessing bug as the computations are done in parallel. Can you open a proper small bug report?
