DTE Filter

Days To Expiry(D.T.E.) Filter​

Have you ever considered backtesting your strategy only on the expiry day? Have you ever thought about how your strategy performs as the expiry day approaches?

At AlgoTest, we understand the importance of customizing your strategy to maximize results.

Our convenient DTE filter allows you to tailor your approach based on the days remaining until expiry. This feature is designed to optimize and fine-tune your strategy according to the specific distance from the expiry day of the instrument.

What is DTE?​

DTE stands for "days to expiry." In simple terms, you can adjust your strategy based on the number of days remaining until the contract expires.

For example, if you want to backtest a strategy only on the day of expiry, the distance from expiry is 0 days. This is commonly referred to as "0 DTE." This approach will display the results specifically for the day of expiry for the particular contract.

Lets take an example of Nifty and assume Thursday is the expiry. How are the days selected based on the distance from the expiry?

DTENo. of Days from Expiry
Day to Expiry = 0Expiry day, i.e., Thursday
Day to Expiry = 11 day before expiry, i.e., Wednesday
Day to Expiry = 22 days before expiry, i.e., Tuesday
Day to Expiry = 33 days before expiry i.e., Monday
Day to Expiry = 44 days before expiry i.e., Sunday
Day to Expiry = 55 days before expiry i.e., Saturday
Day to Expiry = 66 days before expiry i.e., Friday
