Report to say Waddell stoked flash crash: source
The report will not name Waddell, which sold a large order of e-mini futures contracts during the plunge, according to the source, who requested anonymity because the report has not been made public.
But the report will describe Waddell's trade as a single trade by an entity, the source said.
