I'm a college student. I have money--albeit not much. I'm a computer science major with a stats minor. With that being said, I'm interested in starting to trade. For now, I'm more interested in being able to build strategies; I want to test strategies for quicker trades--10+ a day. Most software I see doesn't really have in-depth historical data to test. So, is using the E*TRADE API a good way to collect data with ten second intervals? I'm interested with building my own dataset to test on. Later on, is the API a fine way to make 10+ trades a day? What kind of latency does E*TRADE have, and what are the disadvantages to E*TRADE?
