KAIRON
Practice

▸System Overview

phase 1 · human-in-the-loop

Kairon is an AI-supervised trading platform. A TradingView strategy fires a webhook; an AWS-hosted AI agent validates the signal against five deterministic risk filters; the proposal lands in this terminal for the owner to approve; on approval, a Lambda places the order on OANDA. A reconciler reads broker fills back into the journal every five minutes. The system is currently wired to the OANDA practice account — no real capital is at risk.

▸The Validator Agent

strands + bedrock opus 4.7

Every webhook is forwarded to a Bedrock AgentCore runtime running a Strands agent on Claude Opus 4.7. The agent has access to five deterministic tools — not free-form decision making. It must call them, read their outputs, and emit a verdict of APPROVE or BLOCK with reasoning.

Median validation latency: ~13s. Tool calls per signal: 4–5. Cost: ~$0.05–$0.15 per validation.

▸Why Human-in-the-Loop

phase 1 control

The agent recommends, the owner decides. APPROVE proposals are visible in this terminal; the executor only places an OANDA order after a click. BLOCKED signals are persisted with reasoning for audit but never reach the order book.

Phase 2 (full autonomy) is gated on 30+ closed paper trades, Sharpe ≥ 1.0, max drawdown < 15%, and a clean run through a high-volatility news event.

▸Risk Filters

every signal must clear all five
01tool
check_stops_sanity
SL/TP direction valid relative to entry, sane reward:risk ratio.
blocks: Inverted stops, flat-line stops.
02tool
check_volatility_regime
Live spread, ATR ceiling, news-window guard.
blocks: Spreads > 3 pips, news-window trades.
03tool
check_risk_rules
Daily/weekly/monthly PnL gates and 10% margin cap.
blocks: Circuit-breaker breaches, oversize positions.
04tool
check_correlation_exposure
Currency-block exposure across open positions.
blocks: Pile-on into the same currency block.
05tool
get_market_snapshot
Live OANDA bid/ask used by the four checks above.
blocks: (read-only data tool)
