Importing custom created csv

I've created a csv file which has all NSE symbols 1 min data since 2015. The file size is over a few GBs. I keep adding new rows to it every minute as I get further data.

When I try to pull this csv through amiquote, it downloads the full file every time.

What should i do to make amiquote download only the latest part of the csv and not full download everytime?

AmiQuote expects ticker list, NOT the csv file with quotes.

To import data you don't need AmiQuote at all. You can import data directly into AmiBroker using Import Wizard

And by the way: it is NOT good idea to keep everything in one file. You should have ONE file per day and import just a daily file. That it optimum solution.
