I want to buy 1lot eurusd , you want to sell eurusd 1 lot. I dont know you (since i have no direct access to you and have no knowledge of each other) and dealer is who we go to. Your a breakout trader, im a buy limit trader, my buy limit sitting at 1.0050 your short stops sitting af 0.9950, dealer steps in, sold to me at 1.0050, and is short, now im long, then he uses your short stops to cover his long, shorts, now you short he covered im long. He net 100pips, i have my long order you got your short order. Stop hunting, and market making.
So he provided a bid ask spread, but since the orders are there already, he can just hit my orders and your orders. Only reason why this example is so wide is because 2 customers only. In reality its many people hitting them, so they are always moving in and out of orders and also to compete with other mm they have to make it competitively priced. And also, in reality, things are not so simple, this is a simplified version of it.
His job, is to match orders, otherwise orders will sit there until something happens. Also part of his job, is providing liquidity to markets when needed. If you see gbpusd on hourly charts, for the last few days, do you see spikes to both the upsides and down sides? Thats where the stop hunting is. And part of the mechanics is this.
His book is short when he sold to me, in anticipation that he can buy from you, when he is done buying from you, he is flat.
So in a bear market, lets say the main trend is still down, and he anticipates a down move, but day traders are covering their shorts, that makes the dealers short to buy from the day traders, and have more short orders. So sometimes other customers could also come in and he can pass some shorts to them if they are bearish too.
Also you never know whose looking the price, quote away from fhe markets, and you can be taken out.
See how the process goes from the picture?
