Sorry, newbie question. How can I add candlesticks to my platform?

Dear all,

I'm new into MT4 world and I was recommended this great forum. I haven't found through the search engine what I'm looking for, so I understand it must be a very noob question, sorry :(. Here I go. How can I add candlesticks to my 1m chart? I know I'm working with Alpari and downloaded their 1m data, but many bars are missing. Could someone tell me where can I find the file they're stored in in order to add manually the ones I need?

Thank you very much in advance.

Manuel
