End of Day Option Data

In order to properly use OptimalTrader, you must have "End of Day" data. Our end of day download service contains all of the quotes at the end of each day for all options traded in the U.S. equity markets. We keep five weeks of daily data on the server so that you can be sure that you do not miss any data. During your free trial of OptimalTrader, you will also receive a free trial of the end of day service.

When you purchase OptimalTrader, you can either subscribe to this service as a monthly subscription, or pay for one year in advanced at a reduced rate. So when you purchase OptimalTrader, remember to add this end of day service too. To subscribe monthly, on the bottom of the Purchase page you will see a subscribe button. Click on it to subscribe.

Back Test Data

If you want to do back testing with OptimalTrader, you will need to purchase "historical option data".  OptimalTrader uses data from www.HistoricalOptionData.com for back testing purposes. Please purchase your back test data from that web site.
