I am not sure how this discussion became so hostile.
I am not a programmer, I am however a trader with both retail and institutional side experience, since the passing of the Commodities Futures Modernization Act in December 2000. (Seeing you have 20 years of experience I assume you worked for a desk prior to 2000?)
While a programmer may need to see the code behind a system to copy it, a trader can spot 'anomalies', patterns, and other clues simply following the way a system trades, when it trades, and what it is trading. Perhaps this is not as accurate as having the full code, and perhaps this is over zealousness on my part to protect it, but in the end all I want to do is protect my investment and be sure our system is able to perform up to a certain level.
Sometimes it can be difficult to interpret text, and I apologize if I came off as being rude. That was not the intended purpose of my messages.
