on contrary side, your first sentence mentioned big institutional can move the market. what is the purpose of big institutional trading the market? do they have same goal as retail trader? make money from the market or their purpose is fixing price to a "justifiable" level to reflect the current economy status? or there is something else?[/QUOTE
I said they can, and not that they are necessarily doing it.
It depends on their purpose for being in the markets but everyone who is trading want to transact at the best possible price so they can make money for themselves, or for their client/s.
by moving market, i assumed big institutional when trade, the rest of the bigger firm let each other know and they all follow the same direction, thats why market price move?
I'm sure they have visibility of each other's positions and can work with each other to move price in certain directions or they stay out of the way and let others do their moves.
Its a complex topic and there are many players so there are many possible scenarios.
and the next question leads to all those signal provider and charging a fee for it, why it would make sense charging ppl receiving trade signal if you want the market goes to your favor, u suppose to let more people know, charging fee only let small group of paid cust know, which is the opposite.
Well, the majority of retails traders lose all of their money and even if some of them follow profitable signals they can still lose money because they are often under-invested.
They don't have enough capital to handle large price moves so sooner or later the broker will take their money.
