RenTec uses Hidden Markov Models in trading.

The technique generated 60% returns per year over 30 years.

One of the co-founders of RenTec's name is in the algorithm!

Here's how it works: Image
A Hidden Markov Model (HMM) is a statistical model used to represent systems that evolve over time with unobservable (hidden) states.

It is widely applied in areas such as natural language processing, speech recognition, and bioinformatics.

And in trading:
HMMs are particularly useful when dealing with sequential data, where the underlying process is governed by probabilities.

Backtesting options strategies sucks.

• Millions of contracts
• Weekly expirations
• Assignment if ITM

Now, you can backtest options strategies in a few lines of code.

Here’s how (with a link to historical options data): Image
Optopsy is an analysis tool for options trading strategies.

• Generates strategies from raw historic data
• Uncover performance statistics for combos
• 12 strategies built in including strangles

We’ll use 5 years of historic options data on RUT for the analysis.

Let’s go!
First, import the libraries we need.

Optopsy is light with very few dependencies. Image
