Do you guys author this stuff in-house, or do you use specific software packages for this stuff? Anyone care to comment?
How much does superderivates do for you, and where does it integrate into a chain, for say, something like market making?
Retail traders just need a calculator (can use the PC one but I prefer the old way, those that cost $1, made in China). Institutional traders use fancy gigo packages. Do you have any specific questions? What is risk management for you? You know different people have different ideas about it.
It was an open-ended question because someone asked me what I use and I didn't know how to answer, other than to say just in-house tools.
