Bandar = Dealing Desk brokers

Dealing Desk = Bandar = Bucket Shop.What it means bookie? This means that they are in a position against your trade, if you loss then they will get income. Your loss is $ 1000 then the city will receive $ 1,000 income. This is how the broker city.
Broker airports generally would limit trading style clients, and is also coupled with a number of 'Trading Terms' profitable on their own. This happens because the Conflict of Interest between the broker and the client is very high. It also opens up opportunities for fraud without the knowledge, such as by way of order execution dilambatin, frequent server down, hang, requotes, not price movements (freeze), stop loss hunting, prohibited the use of this technique, price manipulation, etc. Another so that you easily lose / loss
So to keep people interested, then they usually perform with a variety of lure and fantastic facilities, such leverage could be up to 1: 500 and even 1: 1000, interest-free, spread sometimes super small and fixed (not corresponding market), bonus berjibun, can transfer2an with 3rd parties, and other things which aims to attract people so as soon as possible mensetor money in them.
Actually, one should not trading through brokerage city. But should look great so strong bayarin you if win + MUST be regulated in order not to cheat so against you (so that they can be controlled within reasonable limits)

Broker Non Bandar = Non dealling Desk / NDDFeatures and characteristics of the broker Non dealling Desk / NDD:

    They meengambil benefit only from the difference in the spread.
    They continue the order (position buy / sell) from the client to the liquidity providers to its partner broker (bank could be great or even other large brokerage)
    Does not limit the customer trading styles such as scalping, hedging, trap, etc. Why can freely? because there is no Conflict of Interest between broker with clients.
    Because NDD, prices available at the client yes there is without any changes or interference on the part of the broker. As a result, the price / fixed spread is not possible (spread surely suit varying market / variable). Usually moments before the news could spread stretchy-stretchy. But there is also a good side, the price will be more transparent and candid.
    Generally leverage given tidalah too high. All must be in accordance with what is in the real markets.

As for the non-dealing desk broker there are 2 types: ECN and STP.
Type ECNECN broker types are actually participate in the market as well as large banks that serve as liquiditor, or bring together sellers and buyers among users (not dibandarin).
Type STPBroker STP (Straight Through Processing) is thrown again broker orders to other brokers, usually thrown to ECN (but if he threw to the Dealing Desk broker yes cilaka too :))
Both types of ECN and STP broker will not fight your trading, and instead they prefer you win or many trade (much frequency / scalper), because that would mean for their intake.

Broker HybridThere is one more, namely the type of broker Hybrid. Which is a combination of a dealing desk and ECN / STP. Usually this type of broker would membandari to order the coins or small (micro, mini), but for large lot orders will be processed by the ECN or STP.
ConclusionGetting to know the broker included in these categories would certainly tricky, given the process entirely behind the scenes we could not see. Many of them false ngakunya brokers ECN / STP is not. Jelilah in observing the bids and consider regulation of the broker.
