I work with meta stock data and have a different sours to get it , i then import MS DATA (Last) to NT7 , at this point every is fine and works great .
Next day i must up date EOD price... i do , when i import again via NT7 (Historical Data Manger) the Data get corrupted .
At first i did not think it's NT 7 , so i deleted my MS DATA and up date all new with same result DATA CORRUPTED ... finally before i give up i tried to reinstall NT 7 , and “vwala” all thing is working again .
HAVE A HAAAPppPY AND SAFE NEW YEAR ALL
thankyou
