Market Analyst, China

Trading is the fairest job one can have. With our own actions, we are 100% responsible for the reward or loss on the P&L. On this path, our talents and efforts can lead us to a life of abundance and freedom. For me, the ever-changing market goes beyond mere fundamentals or technicalities, to become a kind of mirror to human consciousness. I feel grateful being a Market Analyst and I love my job, both the joyful parts and the common frustrations.

Katarzyna Rebala

Senior Accountant, Warsaw

I have been working in OSTC for 6 years now. Accounting wasn’t always my major interest; I graduated from environmental protection studies and management studies. I started my career in PR but I never really felt suited to it. I asked myself: what job will be right for me? The answer came soon after I knew that my job must give me a specialized knowledge and not only soft skills. I decided to become the best accountant ever! I began by investing in accounting studies, taking several courses and finishing a course for chief accountants. For the first two years, I worked for accounting offices, before joining OSTC for a new chapter in my career. I started as a Junior Accountant, then Senior Accountant and finally, I was promoted to the role of Chief Accountant. Quite honestly, I had never imagined that I could work in one company for such a long time but OSTC changed my point of view. There are several reasons for this, including the family atmosphere, amazing people and of course, a chance for my own professional development. I can always rely on my Finance Team. They give me so much support which makes work a pleasure, not a duty.

Ravish Raja

Market Analyst, India

My journey at OSTC has been a roller coaster ride, but I continue to enjoy every bit of it. I come from an engineering background, which meant I went through a steep learning curve to get up to speed with the fundamentals of finance and core trading terminologies when I joined. Every day is a different experience, so it’s important to learn how to manage your emotions on the days when things don’t go according to plan. You’ll almost certainly lose money in the beginning, but OSTC has a great philosophy of inclusion and guidance so there’s always people looking out for you, having your back, guiding you at every step. If you are performing well, you are rewarded with bonuses, which have been at times more than my actual salary. From my experience in the industry, what distinguishes OSTC from other trading firms is the faith and commitment it has toward its employees.

Trader, Lodz

I started to trade markets during my studies, when I was 20 years old. Always changing, always risky and rarely predictable – markets quickly became my passion. As such, OSTC went from a part-time passion to a full-time trading job. I’m convinced that it’s impossible to make money in the market if you don’t give it your all. OSTC gave me a systematic approach and infrastructure within which to learn and improve, which I believe is important. In order to win a lot, I need to stake a lot, but only if I’m feeling confident. Timing is everything, so I’m getting better at knowing when to stake a lot and when to hold back. That’s the way I’m trying to go.

Market Analyst, China

Trading isn’t an easy job. It requires real discipline and focus. There are good days when trading plans are executed successfully, and there are days when the market seems to go against each and every one of my decisions. Over time, I’ve learned to appreciate that how I manage my trades on the tough days is crucial in determining my overall performance. These days are challenging, but they’re also the moments for great learning and growth. Nevertheless, the market always offers ample rewards for hard work. Being a trader is definitely a fascinating and exciting career path.
