Tier1 Trading Objectives … Speculative Profit making or Task achievement?

A question that I have been pondering recently is to do with what actually moves the market or to be more exact what is the Objective of Trades that the institutional traders make.

To put it simply my question could be put like this.

What approximate percentage of the weekly movement of price is made up of trades that :-

1) Are similar if not exactly like the trades we make as retail traders. Speculative Profit making. We are free to choose entries, direction, sl and tp.

Or.

2) Traders have a task to achieve. For whatever reason.
I.e. A trader HAS to trade UsdJpy Short, within perhaps a given timeframe. To achieve a specific result. Profit making is of course a factor, but not necessarily the primary one.

I guess I am trying to assess the randomness of the markets a bit more than I currently understand it. What affects it?. Why?.

Many thanks in advance for any informed thoughts, or even educated guesses.
