4 min readRate of Change (ROC) is a technical indicator used in financial markets to measure the percentage change in a security's price over a specified period of time. In Dart, you can create ROC by first calculating the percentage change in price, and then applying the formula:ROC = ((currentPrice - previousPrice) / previousPrice) * 100You can create a function in Dart that takes in a list of prices and calculates the ROC for each price point.

For each day, you can compare the closing price of the current day with the closing price of the previous day. If the current closing price is higher, you add the volume to the OBV. If the current closing price is lower, you subtract the volume from the OBV.

3 min readIn MATLAB, you can connect words and phrases using various functions and operators. One common way to concatenate strings in MATLAB is to use the square brackets operator '[ ]'. For example, you can connect two strings 'Hello' and 'World' by typing 'str = ['Hello', 'World'];'.Another method is to use the strcat function. This function concatenates strings along the specified dimension.

4 min readTo calculate On-Balance Volume (OBV) using C++, you first need to understand the concept of OBV. OBV is a technical analysis indicator that measures buying and selling pressure by keeping track of the cumulative volume flow.To calculate OBV in C++, you will need to create a function that takes in a series of volume data and closing prices. You will then iterate through the data points, and for each data point, you will compare the closing price with the previous closing price.

Next, create an SQL INSERT statement that specifies the values you want to append to the table. Then, execute the INSERT statement using the exec function with the database connection object and the SQL statement as inputs. This will add the new data to the specified table in the database.

The load function will load the contents of the .mat file into the MATLAB workspace, including any image data stored within it. Once loaded, you can access the image data as variables in MATLAB and perform image processing or analysis tasks on them as needed.[rating:a1d39167-d6cc-4129-bda1-33063ad5bdfd]How to view metadata in a .mat file in MATLAB.

7 min readCalculating the Rate of Change (ROC) in SQL involves determining the percentage change between two consecutive values in a dataset. This calculation is often used in analytical and forecasting purposes to understand trends and patterns over time.To calculate the ROC in SQL, you would typically subtract the previous value from the current value, divide that difference by the previous value, and then multiply by 100 to get the percentage change.

6 min readMoving averages (MA) are commonly used in statistical analysis to smooth out fluctuations in data and identify trends over time. In TypeScript, we can compute moving averages by taking the mean of a specified number of consecutive data points. By calculating moving averages, we can see the overall trend of the data and make more informed decisions.
