Introducing Q-API

· 2 min read

At Deltaray we are committed to providing retail traders and institutions tools that help them make informed trading decisions. As part of this initiative, we are releasing a Free API today, which provides access to some of the building blocks of MesoSim and MesoLive.

Q stands for Quantitative​

In trading, the ultimate goal is to increase your capital while minimizing the risk to an acceptable level. Measuring risk is a complicated process. Even the simplest risk metric - Max Drawdown - requires you to keep track of the highs and lows in a rolling manner. When evaluating strategy performance, it is advised to study the Risk-Adjusted Return (e.g., Sharpe or Sortino), which takes both returns and drawdowns into account.

QuantStats​

In MesoSim and MesoLive we are using Ran Aroussi's excellent QuantStats library to calculate quantitative metrics and create portfolio analytics tearsheets.

With Q-API we are releasing the tearsheet generation and risk metrics calculation free for personal use. These functionalities are available using the following endpoints:

/quantstats/v1/tearsheet-from-json
/quantstats/v1/tearsheet-from-csv
/quantstats/v1/metrics-from-json
/quantstats/v1/metrics-from-csv

Both endpoints require the user to provide the Strategy Performance and a Benchmark Price (such as ^SPX) as time-series. 

Market Calendar​

It's important to know when we can engage in a particular activity we're interested in. This holds true for trading as well; it's essential to be aware of the market's opening and closing times, including early closures.

Q-API enables the users to access this information using the /market-calendar/v1/trading-hours endpoint. Our trading calendar's historical data dates back to 1998. 

On the roadmap​

We plan to expand Q-API's functionality, including (but not limited to):

  • Position sizing via Kelly Criterion (Formula)
  • Options Pricers
  • Additional market data

Note on MesoSim API​

MesoSim API is currently available to institutional clients only.Therefore, Q-API does not include access to MesoSim's API.
