A big if

is it possible that all the member of this community at the same time,buy or sell (doesn't matter BUT IT MUST BE THE SAME) exact currency?
you should think of sth huge,:)
i mean if we all buy for ex eur/usd it deffinately will go up,there is a big if here,which is the volume of the money that we trade with should be so much

well, first of all, we have to do it from the live accounts. Concerning that the daily turnover in Forex is around 4 trillion dollars and eur/usd is one of the majors. I don't know, I’d say we have to put 10% of market turnover on the table to create a significant movement. It is easier to manipulate with less traded currencies, but since there less traders and more banks it still looks complicated.

We could try to do it on the commodity market. Might work with gold. Now we only need to engage more people. Like 10 000 more at least)))

Looks cool! Can you take me with you, guys!? It is for of us now! We almost have enough people to start!

i doubt it. banks are trading with way more volume than the members on this site in a single trade prolly. Some take $800 billion + positions...

Nice joke guys...
Have you ever heard about Pareto law? (80/20). => It works for eveything you want to analyse:

- Check your own account and you will notice that 20% of your trades represent 80% of your loss.

- 90% of the world richess represent 10% of people.

- This means particular traders are 90% and they represent 10% of the volume.... We will have placebo effect on market. And even if it could work... How do you think we will close our trade if no one wants it in the opposite way???

If you look at that from the bank side it can look like a good idea

This theory has worked well for stock markets worldwide where a certain company's stock have been taken for a ride by major players and then set to free fall.

As the volume is low, this can work.

But in forex market it is highly impossible to do such things. Also, banks and other larger institutions don't use the leverages like retail traders do so it is not possible for a major market move impact by any larger institution as well.
