Usage
Fetch tickers list from user filter
Since it is more convenient to use web based interface to set the filters, there are 2 options to filter tickers.
# with raw url
Finviz.tickers uri: 'https://finviz.com/screener.ashx?v=211&f=fa_pe_u5,sh_price_u3&ft=4'
=> ["BHAT", "CEPU", "CIH", "CMCM", "DLNG", "EDTK", "FENG", "JOB", "QD", "SND", "SUPV"]
# with manual filters cherry-picking
Finviz.tickers filters: %w[fa_pe_u5 sh_price_u3]
=> ["BHAT", "CEPU", "CIH", "CMCM", "DLNG", "EDTK", "FENG", "JOB", "QD", "SND", "SUPV"]
Fetch quotes
Each quote contain the OpenStruct with ticker stats and links to the ticker and chart, see example:
[1] pry(main)> quotes = Finviz.quotes tickers: %w[aapl mrna]
[2] pry(main)> quotes.m # If the quote was not requested
=> nil
[3] pry(main)> quotes.aapl
=> #<Finviz::Quote:0x00007fb7189895f0
