Emerging Opportunities In Stocks Trading With Innovative Ideas

Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll detail the emerging opportunities in stocks trading with innovative ideas. 2020 has unleashed the entire world on the battlefield of uncertainty. You cannot assure how companies and firms will evolve in the coming days. With this pandemic, influencing both personal and professional life, our future is not certain. This uncertainty has affected stock trading and the factors influencing it.

Emerging Opportunities In Stocks Trading With Innovative Ideas

Trading is generally considered a risk profession but this is not the case as per innovation in technology. Now, you can easily trade to make profits even if you have little to no money. There are many online services available like Automatic Fortunes, which help users in emerging opportunities in the stock trading market. Participating in a potential growth stock can help you grow financially With trading, you can generate passive income or take it as a full-time job or part-time opportunity, either way, you have a massive chance to make a handsome amount of money.

1. Innovative Technology

Needless to say, advancement in technology has produced plenty of low barriers-to-entry trading opportunities. You can do trading with no money in some cases. While in other cases, little money is needed to put you on the steering wheel of trading. Anyone with patience and commitment can make a killing in this profession. Innovation is introducing a new idea to bring ease and comfort to people’s life. New internet technology has turned the entire world into a global village, interlinking the global market and giving you the ability to make money right from the comfort of your home. Even if you have a full-time job or have a family to support, you can join stock trading to make a living.

2. Trading Opportunities

Normally stock prices are based on technical indicators that mainly influence the large price movements. This is true, such combinations occur once in a while, but when they do, they bring scores of opportunities for everyone. They are mainly termed as trading opportunities. The opportunities in stock trading generally come with a low downside while the upside is high. Every opportunity in stock trading is measured with a score ranging from 0 to 100. The higher score is linked to better trading opportunities and as a result ensuring more profit with the trade. Still, a higher score doesn’t ALWAYS guarantee more profit because some factors like volume balance, trend direction, support, and resistance also influence the technical aspect of stock. It is, therefore, preferred to see the entire picture of stock trading and, more importantly, audit the basic information before trading. Know that risk factor has nothing to do with the score calculation. Two different stocks that contain the same score may face entirely different risks. Some people assume stock trading is a walk in the park; this is not the case in reality. The success of this business is entirely dependent on you. It involves so many paths, where anybody can join the business. You need to well prepare yourself in advance for all the ups and downs of the stock trading.

A. Trading from Home

This seems like the best and easiest way to earn a living because you have flexible hours to work but there is a catch. The minimum equity required for trading to work as a pattern day trader is 25000$. And you need to maintain this amount all the time. If your account fails to retain this minimum, your account will be put on hold until you hit the minimum once again.

B. Proprietary Trading Firms

These firms have become famous among the masses due to their attractive and low-free strategies. If working from home is not your cup of tea, you might want to join the trading floor where you can typically work as a contractor. You’ll never get a daily wage in firms like these, just the commission you make bringing clients to the firm for trading. There are plenty of benefits to working in a trading company including exposure to trading ideas, meeting with successful traders, free training, performance monitoring, and easy access to capital.

C. Other Options

When you don’t have enough money to invest, it’s wise to get a hold of other trading options that demand less capital. The currency markets and foreign exchange are the best alternatives that require less capital where you can open an account in just $100, helping you control a large amount of money with this capital. These markets work 24/7, giving you the flexibility to collaborate from anywhere anytime. These markets are mainly introduced for the traders who don’t have time to work in regular working hours.

Conclusion

Once you’ve got to know which trading option suits you the best, stick with it. If trading from home resonates with you, make sure the markets you trade with will lie within your interests and capital. And come up with a comprehensive trading plan to get a hold of all complexities in your trading business. This is now your business. You need to apply everything in this business you would otherwise apply in regular business. Work with online brokers and explore other options. If you have a laptop and internet connection, you can make a living trading. Last not least, don’t hesitate to get help from the mentors. They will help you stay on track and how to deal with the challenges you might face in trading. That’s all for today. Hope you find this article helpful.

Introduction to Arduino UNO REV3

Hi Friends! Hope you’re well today. Happy to see you around. In this post, I’ll detail the Introduction to Arduino UNO REV3. Arduino Uno REV 3 is an Arduino board based on the microcontroller ATmega328P. It carries 14 digital I/O pins out of which 6 can be used as PWM outputs. Moreover, 6 analog input pins are available on the board and the clock frequency is 16MHz. Arduino UNO is one of the most used boards from the Arduino family. The robust and clean design helps you shape your ideas into reality. Know that Arduino UNO REV3 is an advanced version of Arduino UNO. The new version includes four solder pads JP2 attached with the pins PB4 to PB7 of the USB ATmega. Uno stands for one in Italian and this name was picked for the release of Arduino Software (IDE) 1.0. The version 1.0 of Arduino Software (IDE) and Uno board both are considered as the reference versions of Arduino, which evolved with time with new features. The UNO board is the first USB board from the Arduino family. Arduino is an open-source platform which means you can get a hold of Arduino boards and software and edit and modify them as per your requirements. Arduino IDE software is free to use for anyone, moreover, as you join this platform you can get help from the Arduino community. I suggest you read this post all the way through as I’ll detail the complete Introduction to Arduino UNO REV3 covering pinout, features, pin description, and applications. Let’s get started.

Introduction to Arduino UNO REV3

• Arduino Uno REV 3 is an Arduino board based on the microcontroller ATmega328P.
• It comes with 14 digital I/O pins out of which 6 can be used as PWM outputs.
• There are 6 analog input pins and the board’s clock frequency is 16MHz which is used for the synchronization of internal functions.
• Moreover, this board includes a power jack, USB connection, ICSP header, and reset button.

• In fact, it contains almost everything required to support the built-in controller. Simply plug this device with the computer using a USB cable or power it up with an AC-to-DC adopter or battery and start playing with it.
• The operating voltage is 5V while the input voltage ranges from 6 to 20 and the recommended input voltage ranges from 7 to 12V.

• Only 5 V is required to power up the board, which we can obtain using the USB port or external adopter, however, it can support an external power source up to 12 V which can be regulated and limit to 5 V or 3.3 V depending on the requirement of the project.
• Internal pull-up resistors are installed in the board that keeps the current under a certain limit. Know that too much increase in the current can make these resistors useless and can ultimately damage the entire project.
• The flash memory is 32KB while the EEPROM and SRAM are 1KB and 2KB respectively. The flash memory is the location where the Arduino program (sketch) is stored.
• While the SRAM is the memory used to produce and manipulates variables when it runs. The EEPROM is a non-volatile memory that keeps the code stored even when board power is removed.
• A reset pin is included in the board that resets the whole board when it is pressed and takes the running program to the initial stage. This pin comes in handy when the board hangs up in the middle of the running program, pressing this pin will clear everything up in the program and again runs the program from the beginning.
• This board carries a built-in regulation feature that keeps the voltage under control when the board is attached to the external device.

Arduino UNO REV3 Pinout

The following figure shows the pinout diagram of Arduino UNO REV3.

Arduino UNO REV3 Pin Description

Hope you’ve got a brief look into the Arduino UNO REV3. In this section, we’ll cover the pin description of each pin incorporated on the board.

Digital Pins

There are 14 digital pins incorporated on the board. You can use these pins as an input or output based on your requirement. These pins receive two values HIGH or LOW. When these pins receive 5V they are in the HIGH state and when they receive 0V they remain in a LOW state.

Analog Pins

There are 6 analog pins available on the board. These pins can receive any value compared to digital pins that only receive two values i.e HIGH or LOW

PWM Pins

Out of 14 digital I/O pins incorporated on the board, 6 are used as PWM pins. These pins generate an analog signal with digital means when these pins are activated.

SPI Pins

The board comes with an SPI communication protocol that is mainly used to maintain communication between the microcontroller and other peripheral devices like shift resistors and sensors. Two pins: MOSI (Master Output Slave Input) and MISO (Master Input Slave Output) are used for SPI communication between devices. These pins are employed to send or receive data by the controller.

I2C Pins

This is a two-wire communication protocol that comes with two pins called SDL and SCL. The SDL pin is a serial data pin that carries the data while SCL is a serial clock pin that is used for the synchronization of all data transfer over the I2C bus.

UART Pins

This board also supports UART serial communication protocol. It contains two pins Tx and Rx. The Tx is a transmission pin used to transmit the serial data while Rx is a receiving pin that is used to receive the serial data.

LED

There are four LEDs on the board. One is a built-in LED connected to pin 13 other is a power LED. And two are Rx and Tx LEDs which operate when serial data is transferred or received to the board.

Vin, 5V, GND, RESET

Vin……. It is the input voltage supplied to the Arduino Board. It is different from than 5 V we get through a USB port. Moreover, if a voltage is supplied through the power jack, it can be accessed through this pin. 5V……… This board contains voltage regulation ability. This board is activated using three ways i.e. USB, Vin pin of the board, or DC power jack. USB supports voltage around 5V while Vin and Power Jack support a voltage ranges between 7V to 20V. Know that, if a voltage is supplied through 5V or 3.3V pins, they will bypass the voltage regulation which ultimately damages the board if the voltage exceeds the certain limit. GND….. This is a ground pin. More than one ground pins are available on the board which can be used as per requirement. Reset… This pin resets the program running on the board. Instead of a physical reset on the board, IDE can reset the board through programming.
