Alternative of Amiquote

[free_spirit]

1. Do we have a alternative of Amiquote? The free version allows us to only update 10 scrips.
2. Can we have a Python script to download NSE all scrips EOD data from yahoo or quandl in amibroker readable format? I tried reading amibroker database but it is in binary format so we can’t directly interpret.
3. Also the Amiquote first reads the ticker list from the Amibroker Symbol list and then downloads latest data for those tickers. And it appends the latest downloaded data to the Amibroker’s existing database. Now even if we download all historical data, we must find some way to append it in Amibroker’s binary database?

I hope I have asked clear questions. Please comment in case clarification is needed.
Thanks in advance
