One way to measure momentum is by the Momentum Indicator. Hence, we will calculate a rolling standard-deviation calculation on the closing price; this will serve as the denominator in our formula. ?^B\jUP{xL^U}9pQq0O}c}3t}!VOu 1.You can send a pandas data-frame consisting of required values and you will get a new data-frame . We can also calculate the RSI with the help of Python code. Sometimes, we can get choppy and extreme values from certain calculations. I believe it is time to be creative with indicators. You'll then discover how to optimize asset allocation and use Monte Carlo simulations for tasks such as calculating the price of American options and estimating the Value at Risk (VaR). You'll then be able to tune the hyperparameters of the models and handle class imbalance.
