I'm very "green" when it comes to this stuff. I thought I'd throw out some questions to those of you "in the know". 1) I currently have an excel addon that downloads data from Yahoo Finance. It only supports Daily/Weekly/Monthly data. Can anyone recommend another source where I can get intraday data nicely formatted into an excel workbook (possibly in a column structure)? Free or pay. 2) Anyone have any tips on automated hand-marking (identifying trending and range bound markets)? I've heard of slopes of moving average. I'm going to hand-mark these areas manually until I can find something better. 3) I currently use RapidMiner to build my models. Anyone have a resource or tips / tricks about getting realtime datafeed directly into a model and spitting out results? hrmm.. i thought i had more questions, i guess ill post more when i remember em. cheers!
