NEW! Improvements to the Backtester

The new ORATS backtester has new amazing features like overlaying long or short stock with any strategy, delta hedging, exiting on spread value vs spread width, multiple symbol combined tests with specific entry and exit dates, and more.

Summary

ORATS has upgraded their backtester with new features such as overlaying long or short stock with any strategy, delta hedging, exiting on spread value vs spread width, multiple symbol combined tests with specific entry and exit dates, and more. They have also launched a Backtest API with advanced features not yet in the online version, including the ability to use signals to enter and exit trades, adjust trades using rules, and combine options backtests with stock only backtests.

We have upgraded the backtester!

Here are the new features:

 

1. The user input area has been improved and more explanations added. Also, a thumbnail of the inputs is shown while viewing the report.

 

 

2. Options can now be selected using both delta and stock out-of-the-money percent simultaneously.

 

 

3. Options meeting the backtested filters are ranked according to a score weighting the multiple entry parameters. For example, if you used ideal deltas, days to expiration, and yield percent criteria, we choose the simulated trade that most closely matches those inputs using a scoring system. More HERE on scoring.

4. We added an exit rule called Strike Difference Percent Value. For spreads, the trade is exited if the value of the spread divided by the strike difference falls below or rises above min max ratios. More HERE on this exit rule.

5. We've added the ability to use multi-symbol entry and exit date simultaneously to control when options trades are entered and exited.

6. We've added the ability to combine multiple symbols backtests (mentioned above) with other multi-symbol or single symbol tests.

 

 

7. The user can now choose to buy or sell stock with option strategy.

 

 

8. We have improved underlying delta hedging, including hedging on an input number of days or delta levels to flatten deltas.

 

 

9. In the trades section, there are now stock trades and profit for delta hedging, covered stock, buywrite, stock overlay, married put, and other strategies that have a stock component.

We are launching the Backtest API with this upgrade. The Backtest API can be accessed programmatically ie with Python.

The Backtest API has advanced features not yet in the online version:

1. Use signals to enter and exit trades using three types of signals: What we call Type 1, that uses our existing Symbol Entry Exit dates method; Type 2 that uses custom single dates like earnings, conferences, or a user custom field; and Type 3 that is a data series like our Core Historical data is mapped to Type 3 signals via the API.

2. The ability to adjust a trade, not by rolling but by using rules to adjust.

3. We have added the ability to combine options backtests with stock only backtests.

4. We have made backend improvements in our AWS cloud infrastructure where we can support 1000's of simultaneous backtests.

We've also made improvements in our backtesting underlying historical quotes data
