Greetings, Some background information: I am a new systems trader and am deciding between Traderstudio and Amibroker based on their price. I have read Curtis Faith's book "Way of the Turtle" where he gives a number of systems and the results in specific time periods. My plan is to first reproduce these numbers so I can verify I know what I'm doing and then I would like to test my trading systems historically. I would like to be able to program a complete system, including criteria to enter a trade, when to increase or decrease size, when to sell, % of money to allocate to each stock, etc and then have the program calculate returns and other data. It would also be nice if I could create the kind of graphs that Faith uses in his book. How do Amibroker and Traderstudio compare in terms of backtesting? Can I program a strategy and an amount of money and see exactly how much I would have made/lost over specific time periods? How many years back does the data go or do I have to purchase the data separately and how much does it cost? Are stock splits handled correctly? I have no programming experience but am extremely intelligent. How long will it take me to figure out either of these programs and how long does it usually take to program a system? Can I use these programs to screen current stocks based on my criteria? Do these programs have access to historical and current volume data as this is a component of my trading system? Thank you very much for any input!
