MQL - write code for news backtester

I am looking to get two MQL functions coded: Function 1 – GetNews(): will read attached csv file with news events into an array (defined as global variable in the expert advisor) (the function will be called from the init() function) Function 2 – IsNewsTime(int MinBefore, int MinAfter, string ccy3 (optional), bool ImpactHigh, bool ImpactMed, bool ImpactLow): will search the array generated in first function and check for both ccies of the current pair if the current minute is within the time range (defined by MinBefore/MinAfter variables) of a defined news event (high, med or low) and returns true/false this check should optionally be done for ccy3 as well if any value passed for this variable the function should run only once per minute and not on every tick functions should work in the same way in both backtester as well as in live trading functions have to be compatible with old as well as new (build 600) Metatrader versions I would like to have the code as short and efficient as possible and would need the code fully commented
