Delivery is a compiled, licensed .ex5 file; source code comes under a separate agreement. - A Strategy Tester report shows that every rule triggers correctly. - An NDA is signed before any work begins. - Bugs found after delivery are logged and fixed; the scope of that support is set in the contract. **We don't** - The strategy is yours; we only code the rules you define. - No robot can know future outcomes, and we won't write anything that claims to. - We never ask for your account details; you run the robot in your own terminal. - A robot written for you is never sold to another client. ## tell us about your method. _ROBOT_ Write out your rules in a few sentences and, if you can, attach screenshots of example trades. We'll pin down scope and timeline, then get back to you. - [Describe your strategy](https://oxarus.com/en/contact?start=quant) → `start_project_brief(topic="quant")` - [info@oxarus.com](mailto:info@oxarus.com?subject=Custom%20robot) → `contact(subject="Custom robot")` ## Actions - [Describe your strategy](https://oxarus.com/en/quant/robots#cta-heading) → `open_page(path="/quant/robots", anchor="cta-heading")` - [How to describe it](https://oxarus.com/en/quant/robots#brief) → `open_page(path="/quant/robots", anchor="brief")` - [Describe your strategy](https://oxarus.com/en/contact?start=quant) → `start_project_brief(topic="quant")` - [info@oxarus.com](mailto:info@oxarus.com?subject=Custom%20robot) → `contact(subject="Custom robot")` - [Türkçe](https://oxarus.com/tr/quant/robots) → `switch_locale(locale="tr", path="/quant/robots")` ## Related pages - [Oxarus Quant](https://oxarus.com/en/quant)
