Moving The Market

[ChaseLa]

Im trying to understand how institutional buying/selling affects price.

Say Wealthy Guy X opens a ECN brokerage account (not through a bank desk) with 50:1 leverage and buys $500,000,000 eur/usd at 1.33000

what would happen over the next few days/hours/minutes ?

Would they automatically profit because the market would slowly move in their favour ?

Thanks

One way or another, the ECN would almost certainly route the order through one of the bigger IB's
Thus nothing would happen, that size is simply white noise in forex markets
