Not really. Retail traders have had that in 2008, some of whom are/were on ET. Probably also in other high volatility days.
$1k is not that much considering not every day is profitable. It doesn't tell me anything, months and quarters are what matter.
I do remember a few traders here at ET that stated (*cough*) they had +million dollar trading day but they worked for a trading firm. In contrast, I don't ever remember any retail trader here at ET that trades from home...discussing their +million dollar trading day although I'll admit I have not read every single message post at this forum.

Yet, lets forget about 2008 or any year from 10, 20 or 30 years ago.
We are not going to see a retail trader (trading their own account)...in today's market conditions...come to ET and say they had a +million dollar trading day. Simply, if someone does say that here at ET...I bet they're at a trading firm. Thus, they are not retail.
