data conversion

I have a scanner which show thrust emerging on stocks,forex etc. It doesnt show historical thrust though and I want to do some back testing. The software only recognises metastock end of day data format and i want to use intraday data in ascii format. To do this you will have to do the following steps. 1. write a program that lets me Convert the ascii data to metastock format ( there is a api attached that can do this and sample data so you can see what it should look like) 2. If the data is intraday convert, is so the scanner thinks it is daily data ie what i'm trying to say is ignore the date and time fields if it is intraday day and pretend it is daily data by just adding dates to it. For example if you had a file which is 5 minute data like this 12/3/08 05:00 1,3,2,1 12/3/08 05:05 1,4,3,2 12/3/08 05:10 2,2,4,3 12/3/08 05:15 2,4,4,4 you would convert it to use the same start date but just add day for each record 12/3/08 1,3,2,1 13/3/08 1,4,3,2 14/3/08 2,2,4,3 15/3/08 2,4,4,4 This way i can use the scanner which will out put the results in daily format 3. Have a text box which lets me type in how many records of the data I want to convert. Ie might want to convert the first 30 records only. should have a label somehwhere which displays the total records.
