Hi, I'm a Masters student and I'm doing a project this summer involving commodity trading. What I hope to achieve is to develop a risk monitoring tool using VaR models in Excel (using the programming language VBA). However, as I have no experience of trading in the stock market I'm not sure what would be beneficial for this tool to do. I don't want to spend three months working on something to find out that traders would never use it. So I would really appreciate it if people (traders) told me what they think would be useful for me to get this tool to do. Also I am focusing on data from the precious metals market (namely gold, silver and platinum) so if anyone knows any useful sites I could use for information/data I would really appreciate it if you would let me know Thanks
