Prices do not move against any one person or against any particular group. There are retail traders that are winning and others that are losing. There are institutional hedgers that are taking money out of the interbank market and others that are putting money in. Prices are not fixed or manipulated by insiders fleecing the average Joe out there and they cannot be.
There is no retail trader psychology. Retail traders are a diverse number of individuals and each of them has his own psychology. For any given market at any given moment there are retail traders that are long, others that are short, and others that are flat. Every one of them got to that position for different reasons at different times at different prices.
There is a market phenomenon called "reflexivity". It was written about by George Soros in some of his more famous books. It is the condition of a large market-wide bias that moves prices in a given direction. It can be described as "most of the people think in one direction" and thus prices move in a given direction. But the "people" in that description cannot be described as "retail traders" or "institutional traders" or "pros" or whatever. They are a diverse group.
