Loved the history. Don't imagine that traders will ever stop trying to get an advantage. I find it fascinating that even the postmaster thought an informational edge was unfair. Important to remember that those with a speed edge, even today, end up quickly converging the markets, and eliminating their own opportunity away.

Also there is a clear distinction between a speed edge and outright illegal acts. Cutting telegraph wires reminds me of modern day equivalents... ie. Enron calling generation plant operators to shut down.
