Forward test

यह कानूनी पृष्ठ केवल अंग्रेज़ी में उपलब्ध है।

A forward test takes the finished strategy and lets it trade new, unseen market data — usually on a demo account first, then small live size. Because the data arrives after the rules were fixed, it cannot have been tuned to fit.

The gap between backtest results and forward results is one of the most informative numbers in algorithmic trading. A large gap usually means the backtest flattered the strategy: overfitting, unrealistic fills, or costs that were ignored.

Covered in depth in Lesson 04: स्वयं को मूर्ख बनाए बिना पलटवार करना.
