1) A good example of a negative spike in the financial markets is the infamous stock market crash of Oct 19, 1987, when the DJIA plunged 22% in a single day. There are plenty of more common, less drastic examples which are periodically seen in individual stocks when unexpected news or events, such as better-than-expected earnings results, reaches investors.

2) This usage originates from the antiquated practice of placing paper trade order slips on a metal spike upon completion.

In programming environments it normally refers to a temporary change, usually for testing purposes (as opposed to a permanent change, which would be called hardwired).
