I started using tiingo recently. It is a very good EOD data provider, as far as data quality, dividend adjustments and number of US stocks, ETFs and mutual funds.
However, I am curious, with other tiingo users, what symbols download speed do you experience? Also, is it dependent on the day of week or time of the day?
My experience: downloading the 503 S&P 500 symbols takes about 20 minutes at 8PM PST.
