(01) Context
Diamond Hand started as a question — can a backend engineer build a trading system that consistently makes good decisions, without giving up the discipline a human keeps trying to break? It's been running ever since, and it's grown into a sizable codebase that watches the market 24/7 across multiple strategies and only acts when several independent layers agree.
The problem
Discretionary trading falls apart the moment emotions get involved. The hard part isn't writing strategies — it's removing yourself from them. The system had to be opinionated, evidence-driven, and incapable of overriding its own rules at three in the morning.
(02) Approach
- 01
Many strategies, one risk budget
Several independent scanners run in parallel, each with its own thesis. They share a single risk envelope, and a multi-layer circuit breaker halts new entries the moment daily or weekly drawdown limits hit — so the portfolio can't accidentally double down on the same idea or bleed out on a bad day.
- 02
Every signal gets a second opinion
Each candidate trade passes through a validation layer that checks regime fit, recent performance on the same symbol, position concentration, and patterns learned from prior trades. If anything's off the trade is downsized or skipped — and there's a hard veto on coin / direction combinations that have lost too many times in a row.
- 03
Self-improving by design
Every closed trade is reviewed and graded by an analyst layer that turns observations into hard rules. Those rules feed back into the signal screener before the next entry. Wins reinforce; losses tighten the screen.
- 04
Validated before it ships
Each strategy survives walk-forward testing across years of historical data, with statistical-significance tests gating every change. Pre-commit review catches look-ahead bias and repaint risk before code lands. Nothing goes live without a paper run alongside it for proof.
- 05
Built like production software
Same engineering discipline I bring to platforms at work — auto-restart, structured journaling, real-time dashboards, alerting straight to my phone, and observability you can actually use. No silent failures.
(03) Outcome
A trading system that's been running for months — disciplined, evidence-driven, and getting smarter every cycle. The latest variant is currently paper-trading at an 85% win rate before it gets promoted to live capital.
