I traded spot FX from 2006-2008 and US and International Equities from 2008-2016, during which time I built up an impressive track record with a Sharpe Ratio of above 3 the entire time with almost no losing months.
I also co-founded a successful retail stock brokerage during that time.
You might be wondering: why did I stop trading? Because it was too stressful to manage my own money while running a retail brokerage as well, so I stopped trading 2 years ago.
I recently resigned from the retail brokerage in order to pursue trading full-time by joining an existing HFT Firm/Hedge Fund. If you're a hiring manager from an HFT firm or a HF, I would love to talk to you!
