stop hunting by intermediary bank ,unauthorized broker

Currently, there is a strategy that is followed by most investment banks around the world, and that is known as Stop Hunting. It attempts to force some market participants out of their positions by driving an asset’s price to a level where many retail traders set their stop-loss orders. The triggering of many stop losses at once generally leads to high volatility, and this can present opportunities to some smart traders who seek to trade in such an environment.

The fact that the price of a currency pair can experience sharp moves when many stop losses are triggered is exactly why many traders engage in stop hunting. Traders who are aware of this fact and have observed this phenomenon of the market try to make of this opportunity by being patient and conservative.
as some banks and brokers are aware of traders stop levels they push the asset toward those stops to collect them and the result is fake break out with which both sellers and buyers are losers .
