What is the best simulator to practice trading at night or on weekends using stored data files? It must offer a graphical/mouse order interface. It must store a trade log and print/export reports showing profit and loss. It must be able to start, stop and reverse the replayed data. It must be able to read ASCII quote files (or some popular format). The data must be simultaneously viewable in a charting program. ============================================ The requirements above seem reasonable (to me), but none of the products I've studied can do all of them. Notes below, to the best of my knowledge: Autotrader - does not have a graphical interface Ninja Trader - offers just a few data files in proprietary Patsystems format requiring Patsystems charting for viewing. No start and stop buttons. Zeroline Trader - does not have replay features. Buttontrader - plays files in a proprietary format which does not interface with any charting software. Bracket Trader - plays back files from Sierra Chart and eSignal. Does not have a reverse feature. Stop button can be slow to respond. Would appreciate hearing of any product that can do it all!
