STP full name Straight though processing straight-through processing, is a bridging method, no trader backstage (traders backstage, English is dealing desk, often translated as "trader platform") in which quotes and control market prices (ie no City), all customer orders are passed directly to the liquidity provider (or liquidity provider, that is, other brokers and banks), and the bid/ask price is determined by those liquidity providers. The STP platform without the trader's back office directly bridges all order information to the liquidity provider, and the liquidity provides the business with the opposite position of the customer to trade, and at the same time, the position is closed by the subsequent transaction with the other party, in order to obtain profit.

Three key elements of the STP Forex platform

1) Liquidity provision
The ECN trading platform will transfer orders to the ECN liquidity pool, which has a large number of liquidity providers that trade between banks.

The STP platform has its own internal liquidity pool, which consists of predetermined liquidity providers, and only those liquidity providers that have signed contracts with STP brokers will be there. These liquidity providers offer the best buy/sell prices for orders from the STP trading platform. The better the liquidity, the better the buy/sell price will be, and the lower the spread will be. If there is only one liquidity provider, there is no price competition between the liquidity providers, which is equivalent to just adding a middleman to trade inside.

2) Spread type
Fixed-point spread STP forex platform: The spread is not adjusted based on the minimum buy-and-buy bid price among multiple liquidity providers, and the spread is always fixed. If the STP broker has only one liquidity provider, the role of the liquidity provider is the only counter-party of the trader, in which case the buy/sell price is determined by the liquidity provider.

STP forex platform with floating spreads: Liquidity providers offer the best buy/sell bids, STP brokers choose the best bid price from one liquidity provider, choose one from another circulator The bid price so that you can provide the lowest trading spreads for your customers.

3) Instant execution or market execution
Immediate execution means that the order will not enter the market directly and will be processed by the broker first.

The market price implementation mentions that the order information is sent to the market, and the price is determined by the liquidity provider in the market.

Moreover, because ECN brings together a large amount of liquidity, these liquidity providers will have a bid between them in order to obtain more orders, so that customers can enjoy lower transaction costs, that is, spreads. And instant transactions at the fastest speed. However, the threshold of the ECN account is relatively high, and there are certain requirements for the initial size of the account, the number of transactions, and the transaction volume, which are suitable for institutional investors and large fund accounts.

9, EA

It can also be translated as “Expert Advisor”, commonly known as Expert Advisor, which is a machine trading process performed by a computer simulation trader's order operation; the computer is based on a pre-edited trading strategy program.

The complete trading logic includes:

1, the admission conditions are judged;

2, judgment of position conditions;

3, position control;

4, the appearance of the judgment.

Traders can write their own trading strategies into EAs, call for various indicators, price loops, historical data comparisons, etc. can be achieved in the EA through programming methods. The computer is much faster than the human brain, so it can quickly trade in some fleeting entry opportunities, greatly improving the quality of trading behavior.

A good trading strategy can achieve stable profitability, even if the loss occurs, it will be controlled within a very small range, and the bad trading strategy may be This causes the trading account to have a huge loss or even a short position in a very short period of time. Currently, there are two types of EAs in the market: fully automatic and semi-automatic.

Refers to some independent securities dealers in the financial market, for investors to bear the purchase and sale of a certain securities, buyers and sellers do not have to wait for the counterparty to appear, as long as there is a market maker to bear the counterparty to conclude a transaction . Through this continuous trading, market makers maintain market liquidity and meet the investment needs of public investors. The market maker compensates the cost of the service provided by the appropriate difference in the price of the purchase and sale, and realizes a certain profit.

In essence, the emergence of market makers stems from the imbalance between buying and selling. In a market that lacks liquidity, this difference in time and space leads to the inability of the transaction to be realized because the buyer and the seller do not necessarily appear or trade the same number of products at the same time. The emergence of market makers has made it possible to trade in demand at different times.

It’s characterized by:
1) In the profit model, profit is controlled by controlling the bid-ask spread, and there is no obvious speculation intention;

3) Risk management, due to the light trading, market makers mainly adopt a hedging method to manage inventory risks;
4) Market-making obligations, if the customer needs to give a quotation at the time of inquiry, the bid-ask spread must be within a certain range, and the minimum trading volume must comply with the regulations;
5) Liquidity provision, when the market liquidity is lacking or the price fluctuation is severe, the market maker makes the transaction realized by providing the quotation.

According to the coexistence model of the bidding system, the market maker system can be divided into a pure market maker system and a hybrid market maker system. The so-called pure market maker system means that the transaction of a certain product is completely completed by the market maker. The so-called hybrid market maker system means that the transaction of a certain product may be completed through bidding transactions or through market makers, and is a mode in which bidding and market makers coexist.

However, the market makers of the MM model usually classify the customers, resulting in multiple obstacles such as slippage, difficult orders, repeated quotations, etc., and the market makers and customers conduct gambling transactions, usually with a large chance of winning, while transparency is high. It depends on the market maker itself.
