markets is handled by three things: 1s accuracy is considered good enough,
transactions are inherently serialized by individual market systems, and
distinct markets are not strongly coupled. None of these things is going to

correctly coordinate transactions in multiple markets, it will be necessary
to achieve subsecond accuracy in LCT -- LCT, because it is LCT that is legal
