HighFrequencyTrading aka HFT comes under less frequently used searches but still has good appraisal value by estibot based on the name. Can get you good price only if buyer is somewhat into Stock related business. Dont expect too much. According to me you can get around 40 USD to 150 USD depends on which users see your sale thread.
High frequency trading is computer automated trading. The people (companys) that do this don't really want to talk about it. So a bloggy WordPress dude would be the enduser, feels if an enduser offers three figures you take it. Goodluck
