here's my stab at the ones i can muster
1) brokers make their money on spread And slippage AND re-quotes - let me explain.
many will say that they cant make money on spread as the market has that spread in it too - however who says you are in the market?
Brokers will play one clients sell against another clients buy - so they never actually go into the market - therefore at that time the spread is all theirs.
They keep a global tally of positions and if it becomes say more long than short then they enter the market with the difference as a hedge.
2. ask your broker
3. brokers can always find a match for your position - silly question as there is one bid and one ask but millions of participants.
4. total control - they make your market - the fact that it matches the real market is just marketing - they are the market maker and they decide what 'fair value' is.
5. dont know what you mean here - if you mean 'how big till you actually enter the market' then i dont know - depends on time of day etc - how long is a piece of string at midnight on the 28th?
6 there are hundreds - every market maker has one
7. when the market moves 1 pip or 10 it merely reflects the current bid and offer on the books. if 'fair value' increases then so will the bid / ask and so will your chart which is a reflection of this.
8.yes, if fair value changes in the market maker's opinion
9. buggared if i know
10 - if you find out , let me know on the back of a postage stamp - that's how much you or i should care.
11. see 'how long is a peice of string at midnight on the 27th january." - trust me, you cant do it yourself.
12.
- for the speculator - to make money
- For the hedger - to avoid losing money
- for the banks - to facilitate the exchange of money for clients and to get the best international intrest rate for their funds.
13. everybody in it gains and loses
14. who cares?
15 it isnt, liquidity changes with the number of deals being made
