Market Makers

[richardg]

Can some one point me to resources on market makers. I know what they are but I'm trying to understand their true power. Many times I'll read things like "the MMs won't let the stock go to x" or "the MMs will pull the stock down to x". I want to understand how true this is.

Thanks.

their true power is that they have a hell of a lot more money behind them than most traders
they in general tend to be banks or brokerages offering a firm bid or ask and their purpose apart from making money is to offer liquidity to the stock

 

[Directional]

a lot of liquidity in markets such as bonds and interest rates is provided by the locals at arcades and prop firms, usually spreading the markets either inter or intra market.

For example, a spreader might bid 100 in the bund and offer 200 in the bobl. Add together several thousand locals doing this during market hours, and add autospreaders into the mix and suddenly you have a lot of depth at multiple levels before you even add the banks into the mix.

or locals legging the futures outrights against the calendar spread will provide liquidity in a similar way.

So all these locals act as market makers (and receive rebates for doing so), but they arent taking any view on the market since they are totally hedged. They just want to take the bid/ask spread for a single tick or so.

GJ was it you that was going to write a "day in the life of a MM or local" or am I thinking of someone else

I'd be interested in reading GJ's article too.

Do people do anything similar in the FX markets? I tried spreading futures against cash but kept on getting legged out.

there was another thread on the go about this a little while back, that had some good contributions from traders: http://www.trade2win.com/boards/showthread.php?t=18916

What do you need to know? As am Ex market maker ( 17 years) I can probably help to remove most of the myths- such as the two quotes you've used. This sort of crap is normally used by lousy traders trying to blame someone else for their own failings and losing money.

If supply and demand dictate that a stocks should go to x then it will go there. No market maker is going to sit on an offer, holding a price down if every hedgey in the world and his mates are buying. UNLESS the MM has a decent order to sell, which of course brings us back to the simple laws of supply & demand .
