/// - It should work asynchronously
/// - The executing thread shouldn’t be blocked during download so we could run this operation even on a UI thread without locking it
/// - Stock quotes should be downloaded in parallel
/// - But no more than 5 download streams at any particular moment in time
/// - Downloaded quotes should be parsed in parallel
/// - In order to utilize the available hardware resources efficiently
/// - Log actions & exceptions
