Data_Downloader by Joydeep downloads scrip-wise 1 min. intraday data with volume, from Google in a jiffy. You can merge it in Amibroker immediately. Google provides data for cash scrips only.
If you want smaller details, I have already developed rtgoogle.xlsm which is there in my link. It can download quotes every 5 sec. without volume from google. The app can be easily modified to append data in one or more files. However, this url is not published by google so they may discontinue it any time. It is also for cash scrips only. Though there is option to download every second, if you download that frequently, google server will think of it as dns attack and block your IP for some period.
I had to develop RTD gui app to backfill data for fno
