7 min readOption sets are an essential feature in Swift that allows you to define and work with custom sets of related options or flags. They provide a flexible and type-safe way to manipulate multiple options simultaneously.To work with option sets in Swift, you need to define an enumeration using the OptionSet protocol. This protocol requires you to specify a raw value type, typically an integer, that represents each option in the set.

12 min readThe Hull Moving Average (HMA) is a popular technical indicator used by traders for scalping strategies. It aims to reduce lag and provide a smoother moving average line compared to traditional moving averages. Understanding how to read HMA for scalping can be beneficial for traders looking to capitalize on short-term price movements.When using HMA for scalping, traders typically focus on the following aspects:Directional Bias: The HMA line can indicate the overall price trend.

9 min readAsynchronous tasks are commonly used in Swift to perform operations that may take time to complete, such as network requests, file operations, or fetching data from a remote server. Handling such tasks properly is crucial to ensure a smooth user experience and prevent app freezing or blocking the main thread.

5 min readGenerics in Swift allow the creation of flexible and reusable functions, structures, and classes that can work with different types. They enable the definition of generic placeholders within code that can be replaced with specific types when used.To use generics in Swift, you can start by defining a generic placeholder, typically denoted with the name T, within angle brackets (< >). This placeholder can then be used within function signatures or data structures.

12 min readMoving Average Convergence Divergence (MACD) is a popular technical indicator used in trading. It helps traders identify potential buy and sell signals by analyzing the relationship between two moving averages of an asset's price. The MACD is calculated by subtracting the 26-day exponential moving average (EMA) from the 12-day EMA. Additionally, a 9-day EMA called the "signal line" is often applied to the MACD to generate trading signals.

8 min readEnums in Swift are a convenient way to define a group of related values in a single type. They allow you to define a set of named values that represent all possible cases of a particular type.To work with enums in Swift, you can define an enum using the enum keyword followed by the name of the enum. Each case within the enum represents a distinct value it can take.

11 min readThe Detrended Price Oscillator (DPO) is a technical analysis indicator that helps traders identify cycles and overbought/oversold conditions in the market. It is used to remove the long-term trend from the price data, allowing traders to focus on short-term fluctuations.To calculate the DPO, follow these steps:Determine the desired calculation period: The period chosen for the DPO represents the length of the cycle you are interested in. Common periods used are 20, 30, or 50 days.

6 min readExtensions in Swift are a powerful feature that allows developers to add new functionalities to existing classes, structs, enums, or protocols. They provide a way to extend the behavior of a type without modifying its original implementation.To use extensions in Swift, you simply define them with the "extension" keyword, followed by the name of the type you want to extend.

7 min readIn Swift, protocols are used to define a blueprint of methods, properties, and other requirements that a class or structure should conform to. They allow us to define a set of rules or standards that can be applied to different types.To define a protocol in Swift, we use the protocol keyword followed by the name of the protocol.

8 min readCandlestick patterns are widely used in day trading as a tool for technical analysis. These patterns reflect the price movements of an asset over a specific time period, usually depicted in charts. Each candlestick represents a specific time interval (such as one minute, five minutes, or one hour) and provides information about the opening, closing, high, and low prices within that period.
