depends what you mean by program trade i guess. Thats a pretty generalized term nowadays.
The definition of "program trading" according to the NFA is:
The purchase (or sale) of a large number of stocks contained in or comprising a portfolio. Originally called "program" trading when index funds and other institutional investors began to embark on large-scale buying or selling campaigns or "programs" to invest in a manner which replicated a target stock index, the term now also commonly includes computer aided stock market buying or selling programs, portfolio insurance, and index arbitrage.
