You tend to hear high frequency traders refer to the code that makes pricing and trading decisions as a system, or signal, or model, or (very occasionally) algo (all refer to slightly different things) but I have never heard them refer to the code that makes trading decisions as a bot or algobot.
I'm in the industry, nobody calls it an "algobot". It sounds ridiculous and doesn't really express much.
I'm guessing someone was winding up the reporter, as from reading the article it seems obvious the person is in over their head.
Reminds me of the (possibly apocryphal) story of how a bunch of teenagers made fun of a 20/20 reporter by describing a made up word "mosh pit", and then it caught on.
No-one says this. I'm not involved in HFT myself but I know a bunch of people who are, there is a jargon word, but it's not that.
