5 min readIn Julia, there are several ways to handle exceptions.The simplest approach is to use a try-catch block. You can enclose the code that might raise an exception within the try block, and then catch the specific exception using a catch block. The catch block allows you to specify the type of exception you want to catch, and you can also assign the caught exception to a variable for further processing.Another way to handle exceptions is by using the @checked macro.

10 min readTriple Exponential Average (TRIX) is a technical indicator used by day traders to identify the trend and generate trading signals. It measures the percentage change in a triple exponentially smoothed moving average of the price over a specified period of time. Here's how to read TRIX for day trading:Calculation: TRIX is calculated by smoothing the price data three times using an exponential moving average (EMA). The formula is: TRIX = EMA3(EMA3(EMA3(price))), where EMA3 is the triple EMA.

7 min readArrays in Julia can be created using square brackets [ ]. You can create an empty array by simply using [], or you can create an array with elements by enclosing the elements within the brackets separated by commas. For example, you can create an array of integers [1, 2, 3, 4], an array of strings ["apple", "banana", "cherry"], or a mixed array of different data types [1, "hello", 3.14].
