Change of periodicity of intraday data

Can we change 5 minute data stored in metastock downloader in 15 minute period or 30 minute period ? I mean to change in data file. If not possible in metastock , is it possible in csv file ? is there any tool already available for it ?

Welcome to the forum viv! I'm sure you will find your membership of traderji very rewarding. In Metastock on the right hand corner below you will find several icons. The second from the left is the icon for periodicity. Click that. Select intraday and then select the periodicity you want. You can get the charts in any mulyiple of the base data you have. Getting 15m charts from 5m data is absolutely easy. Try this. I hope this helps.

Dear Laksh, yes my membership is very rewarding.Please understand my previous post again. I want to change periodicity of data file not display on chart. I know very well to change periodicity in metastock charts. Thanks for your attention . Any other suggestion?

No, in metastock its not possible to change the Data in data file !!! You can change the display in charts.

Hi everybody

I have a question about metastock. When I connect a program to metastock as a real time with a periodicity(1 min, 5 min, 10min etc). it shows values correctly but when I change periodicity to daily it shows open and low values zero(0) it is about metastock bug or I have a problem with my program?

note: I use metastock to follow stock market values.
