Check the time period used - MetaTrader 5 Expert | Forex Indicators Download - MT4/MT5 Resources
This function takes two integer arrays as parameters: "allowedPeriods" and "periodsToCheck". "allowedPeriods" is an array containing all time periods allowed by the system, while "periodsToCheck" is an array containing the time periods used by the user in the indicator.
This function iterates over the elements of the "periodsToCheck" array and checks whether each element is present in the "allowedPeriods" array. If any disallowed time periods are found, the function will return "false". If all time periods are allowed, the function returns "true".
In short, this function is used to ensure that the time period used in the indicator is valid and allowed by the system.
