RE: Trade of 1 milion value23 Jan 2021 23:36
The arrival of strange after hours trades has been going on for the last month or so. Typically these arrive just after 5pm and are marked on the London Stock Exchange website with the unusual flags 'TNCP' and 'SINT', eg:-
Apparently 'TNCP' means "Non Price Contribution to Discovery" and 'SINT' is a SI trade when SI is defined as an "investment firm which, on an organised, frequent, systematic and substantial basis, deals on its own account by executing client orders outside [a trading venue]." According to 1onic in layman's terms, it's any firm that matches and fills a significant number of client orders internally.
