-Billions of daily quotes in your pocket – our library is approaching one trillion quotes and growing

-Improve your trading strategy – replay trading sequences at any speed, and see what you missed in real time

-Download full day market prints as cvs files (timestamps are in unix format; to convert to NY time use =(([unix format]+(-5*3600000))/86400000)+25569 and set custom format to m/d/yy h:mm:ss.000)

Note: Surveyor is not a real-time trading tool, nor is it a portfolio tracking tool. The most recent data is from yesterday. It is designed to help you study the past and learn from history, so you will not be condemned to repeat it.
