The moment of what was expected to be the day of its greatest celebration became the day of its greatest humiliation.

BATS Global Markets, just shy of seven years old, was offering its stock to the public for the first time, on March 23, 2012.

On its own listing exchange. Using its own purpose-built auction process. And, when done, to be traded on its main stock exchange.

But a 'software bug' impaired the auction and the company withdrew its IPO.

Here is a continuing compilation of reporting by Securities Technology Monitor and Traders Magazine, tracking how the technically-driven initial public offering of stock by BATS Global Markets went wrong.

And signs that the company designed for Making Markets Better is righting itself.
