What is Scalping: Scalping is the trade that starts with two or three pips and is opened for 15-20 pips. And the trade opened in this short time is called scalping. Those who do scalping are called scalpers. Scalping trades do not have any fixed time limit but stop loss and take profit are essential. The correct timeframe for scalping is 5,10,15,30,45 minute timeframe. When you go scalping on the 15 minute time frame you can see where the market is going on the h1,h4,d1 time frame. If the 5 minute timeframe is a buy position and the 15 minute timeframe is a buy position then you can enter scalping. And if these two charts give two types of signals, then you should not do scalping. Never scalping against H1,H4 timeframes. If you go against the H1, H4 timeframe, you will float in the forex market or currency ocean. You can be a gainer in the forex market if you go against the trend (market direction). There is no better timeframe for scalping than the 15 minute timeframe. When you see H...

Network Topology Computers installed in a network system can be connected to each other in various ways. Such a structure is called a computer network topology.

In this organization, computers and devices send signals to each other's nodes through buses. At this time other computers and terminals connected to the bus line examine the signal and only the ...

| Nano Technology   The word Nano is derived from the Greek word Nanos. Which means a dwarf or a miniature human or other creature with magical powers. The technology or technology that is used to convert molecules or atoms into nanoparticles or molecules or atoms is called nanotechnology. In detail, when molecules or atoms are changed to a nano-meter scale using a special technology or device to enhance the performance of an object, that technology is called nanotechnology. Nano is basically a unit of measurement. Which is equal to one billionth of a meter. For ease of understanding, the hair on our head is 80,000 nanometers wide. The atom, the smallest unit of matter, is one-tenth of a nanometer. The DNA contained in living cells is 2 nanometers wide. Molecules or atoms are a few nanometers in length, so the molecular-atomic measurement scale is called the nanoscale. The principle of this technology is that everything will be made at the nanoscale. The main advantage of this...

Market order: There are two types of market order. namely- 1. Market Execution Order 2. Market Pending Orders 1. Market Execution Order: When buying/selling a pair at the current market price, it is called a market execution order. That is, when we sell directly at the price, it is a market execution order. 2. Market Pending Order: If you want to buy/sell in the future at a price other than the current price, it is a market pending order. ** Pending order means that even if you are not in the market, your pending order will be active if the market goes to the rate at which you place a buy/sell order in the market. That is, pending order is the name of determining a certain rate before going to the market. There are four types of market pending orders. Namely – 1. Buy Limit 2. Sell Limit 3. Buy Stop 4. Sell Stop 1. Buy Limit: Buy limit is lower than the current price if you want to buy then you have to give Buy limit pending order. In case of buy limit pending order, you can never place...

What is trend retracement or correction : When the market price moves against the main trend, it is usually called trend retrestment or correction. When a small movement is made against the uptrend, it is called a retest or correction. A sudden downtrend is called a retest or correction. This movement of the market against the uptrend is a market correction or trend retracement. Essentially, market movement against the main trend is called a retracement. Same definition for down trend. If there are more buyers than sellers, the market goes down. Again, when there are more buyers than sellers, the market starts to rise. This is one of the reasons for retrestment or correction. Sellers cannot hold the market against the trend for long. For this, the market makes small movements. And these small movements are retrestment or correction, when the presence of buyers in this market is more, then they move against the trend, and when it is seen that the presence of sellers is more, then the ma...

-- Describe main memory of computer. Computer main memory can be divided into two categories based on data storage and retrieval, namely: 1 RAM (Random Access Memory) 2 ROM (Read Only Memory) RAM: The memory directly connected to the motherboard that can be read and written is called RAM. This memory is a temporary memory. Data is stored in RAM as long as the computer has power. RAM erases all its data as soon as the power supply is turned off. Hence it is called as temporary memory. This memory is activated as soon as the computer is turned on. After the computer is turned on, data received from the receiver is stored in this memory. It is semiconductor and direct access memory. Usually running programs and repeatedly changing information and data are stored in memory. ROM: This part of main memory is permanent, non-volatile and non-destructive. Some programs are inserted into this memory when the computer is manufactured. Even turning off the computer does not delete any information ...

Computers are used in observational and research work due to two notable features speed and accuracy. (4) Reliabi...

Trade lock in Forex: The trade lock is to set the stop loss to some profit from the entry point. The entry point is the trade point. That is, the trade line is the entry point. Trade lock is when any trade goes into profit, so that those trades do not close again at a loss, setting a stop loss at some profit from the entry point is called a trade lock. Trailing Stop : A trailing stop will automatically move your stop loss. Your stop loss will automatically move through the trailing stop. That is, if you use a trailing stop, whenever your trade goes into profit, as soon as you go into profit, the stop loss will be set as many pips below the current market price as you use the trailing stop. Tailing stop is 10 pips if you give 100 pips. And giving 200 pips sets 20 pips. When using a trailing stop, if the market goes up, the stop loss will also go up. But a trailing stop will not work if the trade is not in profit. Moreover, Teling Stop will not work if the device does not have an intern...

Internet Internet is a network of networks of computers in different countries of the world. That is, the Internet is a network of computers located in different countries of the world. The number of networks connected to the Internet is currently in the tens of thousands and the number of computers in the billions. Its number is constantly increasing. In 1969, the United States Department of Defense first connected four universities in the country for research through a computer network known as ARPANET (Advanced Research Project Agency Network). In 1982, the Internet started with the use of TCP/IP (Transmission Control Protocol / Internet Protocol) protocol for connecting different networks. The use of internet in commercial or professional work has made the speed of work much more dynamic especially in document exchange. Earlier there were complications in getting documents from one place to another, which is not there at all on the Internet. The following devices are required to us...

Communication model : In the early days of computer networking, various manufacturers made communication software in their own way. Due to the different protocols of these hardware-based software, the software made by one company could not exchange data with the software made by another company. This would be a big problem. Later, a committee was formed from ISO (International Standard Organization) to eliminate this problem. This committee created a protocol model called OSI (Open System Interconnection) to create standard standards for harmonizing all communication software. This model is known as communication model. OSI (Open System Interconnection) Model: The OSI model describes how communication between computers and other networking devices will be developed. The International Organization for Standards (ISO) started working on this model in 1974. The need for the OSI model is felt so that different networking device manufacturers can produce their devices following the same sta...
