Trading is my passion, not my profession
I’m Tanay Roy.
I didn’t come to the markets from a trading desk. I came from data. My career was in data analytics, including leadership roles at two startups. I also hold a CFA (ICFAI) charter.
In 2020 the pandemic hit my consulting business hard. I turned to something I had always been drawn to: financial markets.
The theory didn’t survive first contact with real trading. So I did what a data person does.
If it can’t be tested, it can’t be trusted
I started coding every strategy I came across: from books, websites, YouTube. Then I tested them.
Most of the claims didn’t hold up.
Reading Market Wizards changed how I saw all of it. Trading is a game of probabilities. No single trade matters. What matters is how a method behaves across a large sample, and whether you can apply it consistently.
That became my rule. If a strategy can’t be written as code, it’s too vague to trade. If it can’t be tested, it shouldn’t be trusted.
My loop is simple: build the idea, code it, test it, trade it, analyse what happened, and repeat.
What you’ll find here
This site is where I share that work.
- Scripts. Indicators and strategies for TradingView, with MetaTrader and AmiBroker to follow. Most are free and open source.
- Tools. I’m the founder and chief contributor of JSKAPPS, where I build testing tools like Candlestick Stats, the Binary Option Ultimate Backtester and JSK TradeProof.
- Books. Binary Options Strategy Validation is out now, and Seven Tests Before You Go Live is on the way.
- Research. Backtests, tutorials and notes on testing strategies honestly.
Nothing here is a signal service or investment advice. It’s a set of tools and ideas for checking things yourself.
