Developer Shares How to Wire NIFTY ML Models to Live Broker Data via Dhan API

·1 views

A developer has published technical notes on building a production-grade machine learning trading dashboard using the Dhan broker API for NIFTY options data. The setup uses Dhan's option chain endpoints to fetch live data including implied volatility, open interest, and Greeks for underlying indices like NIFTY and BANKNIFTY. An XGBoost model runs inference on each new price bar to score contract quality and determine entry readiness, with the inference path kept deliberately separate from order execution. The author warns of a known pitfall with Stop-Loss Limit orders and recommends running the system in paper trade mode before going live. The post is framed as a research exercise, with the author noting the ML model achieved 60.5% top-decile directional accuracy and explicitly advising readers to address SEBI compliance requirements before any live trading.

How to Delegate AI Coding Tasks Securely Without Sharing Account Access

Sharing AI accounts or API keys among teammates creates security, accountability, and audit risks that are easy to overlook. A safer alternative involves separating task preparation from task execution, where the requester drafts a self-contained, portable task and the runner uses their own authorized AI subscription. A well-structured task should clearly define the desired outcome, project context, work boundaries, and required evidence, rather than relying on vague chat-based instructions. Sensitive information such as passwords, private keys, or production tokens should never be included in task handoffs. Completing the workflow with a delivery report — covering changes made, tests run, and items needing human review — ensures accountability without transferring account ownership.

Timezone Bug in Django Middleware Caused Endless Auth0 Login Loop

A developer discovered that a login loop in their application was caused by a subtle timezone mismatch in a custom JWT validation middleware, not a broken authentication flow. The Django backend was comparing token expiry timestamps — which are issued in UTC by Auth0 — against the server's local time, which was set several hours ahead of UTC. This made every newly issued token appear already expired, triggering an immediate 401 Unauthorized response on each API call. The frontend's session interceptor would then redirect the user back to Auth0, which silently issued a fresh token, restarting the cycle indefinitely. The fix required just one line change — replacing datetime.now() with datetime.now(timezone.utc) — to ensure the expiry comparison used the correct timezone.

Kubernetes Cost Overruns Stem From Poor Operations, Not the Platform Itself

Engineering teams frequently blame Kubernetes for soaring cloud bills, but analysis of production environments suggests the real culprit is inefficient operational decisions. Oversized resource requests, poor workload scheduling, and underutilized nodes cause clusters to appear full while large portions of compute power sit idle. Teams often overprovision CPU and memory out of caution, yet this can push cluster utilization below 40 percent and paradoxically reduce reliability rather than improve it. Misconfigured CPU limits further compound costs by throttling workloads and degrading application performance without any visible crash. Experts argue that right-sizing resources based on measured demand, rather than worst-case assumptions, is the primary lever for controlling Kubernetes infrastructure costs.

EU Commission's 2022 Foresight Study Examined Future of Platform Economy Policy

The European Commission launched a procurement in August 2022 for a two-year participatory foresight study on the future of online platforms, with a submission deadline of 22 September 2022. The study, referenced as CNECT/2022/OP/0049, was designed to identify ten key topics alongside Commission services and assess long-term trends in the platform economy. Rather than focusing narrowly on marketplace user experience, the project aimed to map possible future trajectories of the platform economy and their broader policy implications for the EU. External contractors, including PPMI and TNO, were engaged to carry out the work, and project materials confirm the study moved into execution beyond the procurement stage. Platform design elements such as recommendation systems, search presentation, and default settings were considered as part of the wider policy context, not as the sole focus of the research.
