7 min readTo write data to a file in MATLAB, you can follow these steps:Open the file for writing using the fopen function. Specify the file name, mode (e.g., 'w' for writing), and encoding if required. For example: fileID = fopen('filename.txt', 'w'); Use the fprintf function to write data to the file. This function allows you to write formatted data. Provide the file identifier obtained from fopen as the first input argument, followed by the data you want to write.

9 min readOn-Balance Volume (OBV) is a technical analysis indicator used to measure the positive and negative volume flow in a security or market. It provides insights into the buying and selling pressure behind a security's price movement. Interpreting OBV involves analyzing the patterns and trends formed by the indicator.OBV is based on the principle that volume precedes price movement. When OBV is rising, it suggests that buying volume is increasing, indicating bullish sentiment.

6 min readTo read data from a file in MATLAB, you can use the built-in functions fopen, fscanf, and fclose. Here are the steps:Open the file using fopen: Use the fopen function to open the file and obtain a file identifier. Syntax: fid = fopen(filename), where filename is a string specifying the file path and fid is the file identifier. Read data from the file using fscanf: With the file identifier obtained from step 1, you can use the fscanf function to read formatted data from the file.

8 min readThe Triangular Moving Average (TMA) is a technical analysis indicator used to smooth out price fluctuations and identify trends in a financial asset's price over a specific period. It is called a "triangular" moving average because the averaging formula assigns higher weights to the prices in the middle of the time period and lower weights to the prices at the beginning and end.The TMA is calculated by taking the average of prices over a chosen period, creating a single value.

4 min readTo perform element-wise operations on matrices in MATLAB, you can use the following approaches:Addition and Subtraction: Use the "+" operator to add corresponding elements in two matrices. For example, C = A + B will add each element of matrix A with the corresponding element in matrix B and store the result in matrix C. Use the "-" operator to subtract corresponding elements in two matrices.

4 min readTo create a matrix in MATLAB, you can use square brackets to define the rows of the matrix. Each row is separated by a semicolon (;). The elements within each row are separated by spaces or commas.For example, to create a 2x2 matrix called "A" with elements 1, 2, 3, and 4, you can use the following syntax:A = [1, 2; 3, 4];In this case, the elements 1 and 2 form the first row, and the elements 3 and 4 form the second row.You can also create matrices with a single row or a single column.

10 min readThe Money Flow Index (MFI) is a technical analysis tool that is used in trading to analyze buying and selling pressure in the market. It measures the volume and price levels to determine the strength and stability of a trend.The MFI is calculated using a formula that takes into account the price range and volume of an asset over a specific period, typically 14 days.

7 min readIn MATLAB, functions are defined using the function keyword followed by the function name and a set of parentheses that may contain input arguments. The function block starts with the function line and ends with the end statement. Below is the basic syntax for defining a function in MATLAB: function outputVariable = functionName(inputVariable1, inputVariable2, ...) % Function body: code statements go here % ... % Calculation or operation % ...

11 min readThe Average True Range (ATR) is a popular technical indicator used in trading to gauge market volatility. It helps traders determine the potential range within which an asset might move over a given period. Understanding how to trade with ATR can provide valuable insights into setting appropriate stop-loss levels, evaluating potential profit targets, and managing risk effectively.To begin trading with ATR, the first step is to calculate the indicator's value.

6 min readTo plot a simple graph in MATLAB, you can follow these steps:Open MATLAB and create a new script file.Define the x-values and corresponding y-values that you want to plot. For example, you can create two vectors x and y to represent the x and y coordinates of the graph points.Plot the graph using the plot() function. Specify the x-values as the first input and the y-values as the second input. For instance, use plot(x, y) to plot the graph.Customize the graph if desired.

7 min readTo run a GUI from another GUI tab in MATLAB, you can follow these steps:Create the main GUI with tabs using the uitabgroup and uitab functions.Inside one of the tabs, create a button or some other user interface element that will trigger the opening of the secondary GUI.Define a callback function for the button or user interface element. This function will be responsible for creating and launching the secondary GUI.In the callback function, create the secondary GUI using the figure function.
