2. Financial Background and Terminology

Intraday Data

London Stock Exchange (LSE) and FTSE supply real time prices for UK listed shares and FTSE indices in ShareScope Pro. The data is delayed by 15 minutes in ShareScope Plus.

All of ShareScope’s US data (NASDAQ, NYSE, AMEX) and many international indices (CAC, DAX, S&P 500 and Dow Jones) are supplied by Comstock, a division of Interactive Data Corporation (NYSE: IDC). Comstock is a leading provider of market data solutions to the global financial community.

Ionic processes the data and within about a tenth of a second passes the data on to you. Depending on your internet connection this data will be available on your computer within another two or three tenths of a second.

The data is input at numerous stockbrokers and market makers around the country and is not checked, either by the LSE or by Ionic Information, before it goes out. On rare occasions data is input incorrectly. This may be corrected with a counter trade but it will always produce either a temporary or a permanent spike. (See Page 14 for a de-spiking option to detect any one-off price spikes.)

Terminology

Offer

The best (lowest) quoted price available if you want to buy shares.

Bid

The best (highest) quoted price available if you want to sell shares.

 

The Bid is usually higher than the Offer, unless there is an auction

 

taking place, in which case they are temporarily reversed.

Mid

The average of the bid and the offer.

Spread

The difference between the bid price and the offer price.

Tick

A change in the trade price.

Trade

A transaction. The LSE doesn’t indicate if it is a buy or a

 

sell; this is inferred by how close the price is to the bid or

 

offer.

Trade price

The price of the last trade.

OHLCV Data

There are a variety of different ways of calculating Open, High, Low, Close and Volume. For the LSE market we use: “London Market Information Link - Recommended Display and Derived Information Guidelines”. This is currently available at www.londonstockexchange.com/cmsattach/940.pdf. For all other markets we use the local rules and guidelines. See the LSE document for full details.

Plus, Pro specifications

Ionic Pro and Ionic Pro Plus represent the forefront of cross-platform mobile app development, building on the capabilities of the Ionic Framework to offer developers an advanced platform for creating high-quality applications. These tools are designed to empower developers by simplifying complex processes and enhancing productivity.

One of the main features of Ionic Pro is its robust cloud services, which allow developers to deploy and manage their apps more efficiently. The platform provides features such as automated builds, which facilitate continuous integration and deployment. This means that developers can quickly push updates and new features without the need for labor-intensive manual processes. Additionally, Ionic Pro includes capabilities for real-time collaboration, enabling teams to work together seamlessly in building and refining their applications.

A standout characteristic of Ionic Pro Plus is its emphasis on performance optimization. The platform incorporates the latest web technologies such as Web Components, Angular, React, and Vue.js, facilitating the development of highly responsive interfaces. This flexibility allows developers to choose their preferred framework while still benefiting from Ionic's rich UI components and plugins. The Ionic Native library also enhances app performance by providing access to native device features through simple JavaScript APIs.

Another significant benefit of Ionic Pro Plus is its support for Progressive Web Apps (PWAs). Developers can create applications that not only function as mobile apps but can also be accessed directly from web browsers. This dual capability widens the reach of applications, allowing them to engage users across various platforms effortlessly. The inclusion of a mobile-first design approach ensures that apps are user-friendly and visually appealing, regardless of the device used.

Security is a major focus with Ionic Pro, implementing features like secure storage and token authentication to protect user data. With built-in tools for analytics and monitoring, developers can track app performance and gain insights into user behavior, which can inform future updates and enhancements.

Overall, Ionic Pro and Ionic Pro Plus provide a comprehensive suite of tools designed to streamline mobile app development. By leveraging cloud services, optimizing performance, and supporting the latest web technologies, these platforms offer a powerful solution for developers looking to create innovative applications.
