The Founder



I am Denis Atamanov, founder of the OptionSmile project. 

I have been familiar with options and options trading for the last decade. Since 2014, I trade them on a daily basis using options to build trading strategies or as a hedge for the long-term equity positions in my portfolios and portfolios of my clients. Before 2014, I worked in the pension industry being responsible for the asset management function as a Vice President on Investments of a private pension fund (around $1 billion AuM).

The OptionSmile platform was born initially as my personal tool for the options analysis and trading: from Excel to the desktop application and, finally, to the full-fledged online platform. Started as a simple calculator of options Fair Value based on the historical distribution of underlying security, it has become a powerful analytical platform providing various tools and instruments for the building of the profitable multi-leg options strategies.

I am a big believer in the quantitative approach to trading and investing. In my opinion, math and statistics are indispensable if you try to earn a profit exceeding the average market return  – on the risk-adjusted basis. 

This project is based on math and statistics – quite simple, though, to be understandable for everyone who has just very basic knowledge of probability theory and options trading.

A few words about the pricing

It is free. Yes, I am not going to ask money for using the OptionSmile Studio because it is actually my tool that I use every day for my own trading.

I’ve just decided to make public the interface of already existing software and can afford not to charge for it. It would not cost me substantially less if I did not open it for everyone interested.

In other words, the incremental cost for making it public with free access is not material for me. What is more valuable is the feedback that I’m receiving to my approach, which is somewhat unusual and is not widely used among option traders. I also expect users to share their findings derived with this instrument. 

The only exception is the API – is not free. Contact us if you are interested in the access via API.
