%% Long story short; accidently turned a nice sdow profit into a loss; this is it and that's all/swing more than daytrade, Not really a horror story; simply a non drama stop executed- don't fight the fed.
As far as Forex is concerned, I believe the biggest horror stories happened on January 15 2015, when the SNB suddenly removed the EUR/CHF price peg.
Think you will need just more than words. A daytrading horror story definitely needs proof of trades.
Looking more for a recent Robinhood mishap. Don't expect to find it here, but just covering my research bases.
Jumped on a downtrend at a bad risk point, thought I'd hold and it as downtrend forming, averaged into downtrend, at worst -$1200 got lucky on the pull back and bailed -$20 right before it ran up again. No chasey the market, let and wait for them to come to you, where the Risk is affordable.
Order entry issue / slow cancellation. Violated my margin many multiple times over, loss (six figures) ballooned to over half my account within a few minutes. If I was a few decades older, I might've had a heart attack. The only redeemable thing was that I let the price settle and I came out with relatively tolerable losses. It would have been the equivalent of 1987 for me if I panicked as it happened and liquidated immediately. I believe that's what they'd call a "career ender".
