10 min readThe Average Directional Index (ADX) is a technical indicator used in the field of technical analysis to determine the strength of a prevailing trend. It was developed by J. Welles Wilder and is commonly used to identify the overall strength of a market trend, regardless of its direction (upward or downward).The ADX is calculated based on a series of calculations involving the positive and negative directional movement indicators (DMI) which are derived from the price action of an asset.

9 min readIn Kotlin, exceptions are handled using try-catch blocks. The correct way of handling exceptions involves following a structured approach:Try Block: In this block, you place the code that may throw an exception. It is executed normally until an exception occurs. Catch Block: This block is used to catch and handle exceptions. You can have multiple catch blocks that specify the type of exception they catch. When an exception occurs, the program flow jumps to the catch block that can handle it.

Here's how you can do it:Define the system of linear equations in matrix form: A * x = b Here, A is the coefficient matrix, x is the variable vector, and b is the constant vector.Use the backslash operator () to solve for x: x = A \ b; This calculates the solution x directly.

9 min readThe Keltner Channels is a technical analysis indicator created by Chester W. Keltner in the 1960s. It is widely used by swing traders to identify potential trade entry and exit points based on volatility and price action.The Keltner Channels consist of three lines plotted on a price chart: the middle line, an upper channel line, and a lower channel line. The middle line is typically a 20-day exponential moving average (EMA) of the price.

4 min readTo feed a nested collection in Kotlin, you can follow these steps:Declare a nested collection variable that you want to populate. For example: val nestedList: MutableList<MutableList<Int>> = mutableListOf() Here, we have created a nested list of type MutableList<MutableList<Int>>.Use the add method to append elements to the nested collection. Start by creating the inner collection using the mutableListOf() function.

9 min readPerforming statistical analysis in MATLAB involves several key steps and functions. Here is an overview of the process:Import Data: Start by importing your data into MATLAB. You can read data from various file formats such as CSV, Excel, or text files using functions like readtable or xlsread. Data Preprocessing: Clean and preprocess your data as per your requirements. This step may involve removing missing values, outliers, or transforming data for better analysis.

9 min readIn Kotlin, generics are used to create reusable code that can work with different types of data. When generics are specified as "int" in Kotlin, it means that the code is designed to work specifically with integers.Generics allow you to define classes, functions, or interfaces that can operate on different types of data without sacrificing type safety.
