One trader, one bot, and a public log of both

The short version

I trade Indian index options, and since early 2026 I have been writing the software that does it for me. NineFifteenAM is named after the moment the NSE opens — 9:15 AM, when the bot wakes up — and it is the public record of that work: the architecture, the failures, the costs, and the things I got wrong.

Six months in, the bot has grown from one opening-range strategy into a system that runs well over a hundred strategies side by side, most of them on paper, with a small set allowed to touch real money through a rule-based gate. Almost everything worth writing about happened in the gap between those two modes.

I write for people building something similar, and for traders who want to know what actually sits under an automated system before they trust one.

What I publish

• The journey — what I built, in the order I built it, and why.
• Mistakes that cost me — real bugs from the logs, with the rupee figure when there is one.
• Best practices — the rules and guards I actually run, and the incident behind each one.

What I never publish

• Buy or sell calls, targets, or stop losses.
• My returns, or any performance claim.
• Strategy entry logic or parameters.
• Paid tips groups or broker referral links.

I am not registered with SEBI as an investment adviser or research analyst. Nothing here is investment advice.
