Most retail traders download a “Nifty 500” or “S&P 500” historical database. That database, by default, only contains stocks that are currently in the index.

I'll also cover support/resistance strategies. I'll organize the article with an introduction, explanation of Brokey, installation, AFL code, configuration, strategies, and FAQ.
