And the design loaded into them is exposed and remarkably easy to
read. If you can program it, you can read it back. I suspect it
isn't much different than reading a DLL.
Same is true for programmable DSP chips.
Given the responses this thread has generated, I think a good
solution for securing a trading strategy is to have a key part of it
separated from the strategy code, such as on a remote server or a
hardware dongle.
