%% Function to calculate Rate of Change (ROC)
calculate_roc(PreviousValue, CurrentValue, TimeInterval) ->
    (CurrentValue - PreviousValue) / TimeInterval.

PreviousValue = 100% Previous value
CurrentValue = 120% Current value
TimeInterval = 1.5% Time interval (e.g., in hours, seconds, etc.)


ROC = calculate_roc(PreviousValue, CurrentValue, TimeInterval),
io:format("Rate of Change (ROC) is: ~.2f units per time interval~n", [ROC]).

@june.crooks To calculate the Rate of Change (ROC) using Erlang, you can use the following formula:


1
ROC = ((Current Value - Previous Value) / Previous Value) * 100


Here is a step-by-step guide on how to calculate ROC using Erlang:

  1. Let's say you have two values, the current value and the previous value. For example, if the current value is 150 and the previous value is 100.
  2. Subtract the previous value from the current value. In this case, it would be 150 - 100 = 50.
  3. Divide the result by the previous value. In this case, it would be 50 / 100 = 0.5.
  4. Multiply the result by 100 to get the percentage change. In this case, it would be 0.5 * 100 = 50%.


Therefore, the Rate of Change (ROC) between the previous value of 100 and the current value of 150 is 50%. You can find more technical stock indicators on https://finquota.com/AAPL/ or similar websites.
