High Impact news function filter

Hello,

I would like a function to filter high impact news from forexfactory calendar to use in expert advisors.

The function has to disallow trading some time before/after the time when High impact news appears.

It can be a bool function and return true or false according to imput values. 

Function Inputs

- Currency: USD, EUR, GBP, CHF, CAD, AUD, JPY (2 currencies should be passed to the function to avoid trading if there is a high impact news on any of the 2 currencies)

- Avoid trading before: YES/NOT

- Time to avoid trading before news: Input_Before_Time

- Avoid trading after: YES/NOT

- Time to avoid trading after news: Input_After_Time

Function Output:

- True or false (The function should only return TRUE or False if trading is allowed or not according to the imput parameters)

The function should be written in clear code.
