Multiple Currency Scanner for last Highs and Lows

Hello,

I need an EA (not an Indicator!) which scans through 28 major pairs and shows on the screen in a table the highs and lows for the last closed candles for this 28 pairs. In the setting menu, I want to specify the 28 pair names and the timeframe for the scan.  IMPORTANT: I already ordered such an EA, but the coder did not know that for this multiple currency scan the EA must update before the history data for all 28 pairs and he did not know how to do that. That´s why I looking now for a coder who can do it. Without updating the history data for all 28 pairs, the scanner shows the wrong or old highs and lows!!! 

I want at the end the open .mql4 file, because I want to add later some stuff.

Thank you

Roland
