Daily Updates Service

Daily updates Wizard is a service complimentary to Data Download Wizard – all the data available in Data Download Wizard can be delivered to you on a daily basis if you subscribe to our Daily Updates Service. Simply define a set of stocks and select the dataset and we will send daily updates to your email (data will be delivered as CSV files). You don't need to check the site every morning looking for a new data - everything will be in your Inbox. We usually provide the data by 6:00 AM EST (EOD data for the previous trading day).


While the service membership is free you will be charged per actual amount of downloaded data (see Data Fee section below). There is also a minimum monthly data fee of $10 - data equivalent is a month of daily updates on Volatility Surface data for a portfolio of 8 stocks. The data fees will be charged when accumulated fees exceed $10.00 or at the month end, whichever comes first.
