I trade through the FYERS API and need a compact piece of code that will handle my order life-cycle end-to-end. The logic is already clear in my head; I simply want it translated into a reliable script that can be launched from my workstation or a small cloud instance. Core functions I must see working: • Step Order Modification – every time price moves by my predefined interval, the script must automatically adjust the target or stop as instructed, without cancelling the original order ID. • Trailing Stop Loss – the stop should trail price tick-by-tick (or by the step value I feed in) and tighten only in the favourable direction. • Ladder / Scale-in & out – ability to pre-load multiple price levels and sizes so the position builds or unwinds progressively. I am fine with Python or Node, provided you use official FYERS endpoints and keep external libraries to actively maintained, open-source packages. Acceptance once I can: 1. Run a dry-run mode that logs every REST call instead of executing. 2. See real orders hitting my FYERS test account and behaving exactly as specified above. 3. Edit a simple JSON/YAML file to change symbols, step size, trail distance, and ladder levels without touching the main code. If you have built similar execution layers before, especially on FYERS or comparable broker APIs, I’d like to see a quick demo clip or repo screenshot. Code should be cleanly commented and delivered through a private Git repo or zip. I want app
