Which layer? I'll venture a guess that e.g. the special
wiring between New York and Chicago will not include
any language's big run-time system.

According to Duncan Sands (AdaCore video), a french bank
is/was using Ada in some transaction layers.

APL is so popular in financial business that Morgan Stanley
had allowed A+ to be made. Another dialect is specially made
for fast processing of series of data (q, earlier K),
and typically sold in the financial market. Yes, that's
probably not the I/O layer that effects trades.
