Greetings. I'm a mac user and currently trade through the ThinkorSwim desktop trade platform. I want to be able to create some multi day trade strategies using technical analysis and then run a backtest. I'm mostly after very simply moving average crossovers and less involved ideas, so no learning C+ if I can avoid it. I've tried using ThinkorSwim's scripting tools, but they are lacking, as is a library of script examples which a newbe can pull from. Any suggestions pointing me toward the best software/broker option would be appreciated. Thanks! Red
