About Eric Purdy

Eric spent the better part of his adult life turning dead dinosaurs into loud noise as a fighter pilot in the US Navy. Commander Purdy’s twenty year career included tours as a flight instructor, teaching university physics and ethics at the US Naval Academy, and multiple combat deployments in the F/A-18 Hornet.

As a retail trader, he cut his teeth during the bubble era and ultimately found his niche in the fusion of options trading and the creation of unique technical indicators. In 2009, he created the website as the go-to source for ThinkorSwim coders and traders.
