Trading Automation Platform

A custom-built, AI-augmented trading automation platform for the Indian markets (NSE / BSE), with a long-only crypto extension. Visual strategy graphs, deterministic backtesting, paper-first promotion to live, and a full audit trail end-to-end.

What the platform does.

Visual strategy design

Drag-and-drop graph editor with 70+ indicator nodes — classical technical analysis (EMAs, RSI, MACD, Bollinger, Ichimoku, SuperTrend, etc.), Smart Money Concepts (Fair Value Gaps, Order Blocks, BOS / CHoCH, Liquidity Sweeps, Equal Highs/Lows, Premium/Discount, Trend Channels), candlestick patterns, and order-flow primitives. Operators compose strategies without writing code, and every strategy ships with explicit risk nodes.

Deterministic backtesting + walk-forward optimization

Bar-true backtesting on a Postgres-backed historical cache covering 170+ NSE F&O underlyings and 5 indices, plus on-demand parameter sweeps and walk-forward optimization with proper train/test windowing. A strict paper-to-live promotion gate compares the live signal stream against the backtest engine and blocks bots that diverge.

Live execution with safety rails

Multi-broker support (Dhan for NSE equities, indices, and F&O; Binance, Delta India, and CoinSwitch for crypto), each via the broker's own API key. Per-trade risk limits, broker-side margin checks, restricted-symbols lists, and an auto-disarm on any backend restart so live trading always requires an explicit operator re-arm.

What's live in the build.

Strategy & Backtesting

70+ indicator nodes including a full Smart Money Concepts catalog (FVG, Order Blocks, BOS / CHoCH, Liquidity Sweeps, Equal H/L, Premium/Discount, Trend Channels, Inducement, Breaker / Mitigation Blocks, Volume Profile, Anchored VWAP, Ichimoku Cloud).
Visual node editor with live preview chart and parameter sweep / saved parameter sets.
55+ ready-to-clone strategy presets covering trend-following, mean-reversion, momentum, breakout, and structure-break families, filterable by asset class and risk profile.
Walk-forward optimization with rolling train/test windows, robust parameter selection, and out-of-sample degradation reporting.
Daily automated strategy evaluation across the catalog with a weekly performance digest delivered by email / Slack / file.

Execution

Paper-mode and live-broker execution paths share the same engine and signal logic; promotion is gated on a parity check.
Multi-broker order routing: Dhan (NSE), Binance (crypto), Delta India (perps), CoinSwitch (INR crypto). Each customer brings their own broker account.
Order types: MARKET, LIMIT, STOP_LOSS, STOP_LOSS_MARKET; modify and cancel for supported venues.
Pre-trade margin checks, restricted-symbols enforcement, and per-bot live-execution arming with auto-disarm on backend restart.
Long-options bridge for NSE index strategies (NIFTY / BANKNIFTY) with configurable strike rules (ATM / ITM / OTM) and stop-space selection (underlying or premium).

Analytics & Reporting

Real-time bot dashboard with per-bot P&L, last-decision reasoning, and event timeline.
Candle chart with SMC overlays (trendlines, channels, FVG bands, Order Block zones, Ichimoku cloud) auto-detected from the wired strategy.
Per-FY P&L breakdown by venue / asset class / currency, with CA-friendly artifacts.
LRS (Liberalised Remittance Scheme) tracker for cross-border crypto remittances.
TDS reconciliation engine for Indian crypto venues (§194S).
Risk-adjusted performance metrics (Sharpe, Sortino, Calmar) and portfolio attribution (per-strategy / per-symbol / per-broker).
Customer data export endpoint covering the full audit history.

AI Augmentation

LLM critic annotates strategy signals with confidence and reasoning; never overrides the deterministic decision.
BYOK support for Anthropic, OpenAI, and Gemini; local Ollama as the zero-cost default.
LLM-driven trade rationale narrator generates plain-English summaries of bot activity over a chosen window.
Full audit log of every LLM call: model, provider, tokens, cost, latency.

Platform & Operations

Caddy-fronted production deployment with auto-issued Let's Encrypt certificates; one-curl installer.
Daily backfill cron keeps the historical bar cache up to date for 170+ NSE F&O underlyings.
API versioning, rate limiting, secret-redaction logging filter, Fernet-encrypted credential storage with documented key-rotation procedure.
Flutter clients for web, Windows, macOS, Linux, Android, and iOS from a single codebase.

In progress

Currently being built.

Live options execution

Strike / expiry selector and paper-mode routing are shipped; live broker submission for NIFTY options is next.

Tick-derived order-flow analytics

Live Dhan websocket and Binance tick feed are persisting ticks today; the tick-vs-bar parity gate ships after a few sessions of accumulated history.

Planned

On the Phase 2 / 3 roadmap.

Multi-timeframe trend channel discovery.
SEBI Registered Investment Advisor (RIA) registration.
Multi-tenant customer access with per-customer broker-account onboarding (Bring-Your-Own-Account model).
Customer-facing onboarding flow, KYC integration, and subscription billing.

Live development environment

A continuously-deployed development build is reachable at dev.paperstox.in .

Nightly deploy from the active branch.
Login screen is publicly accessible; the dashboard, strategy editor, backtest lab, and bot detail screens are gated behind an account.
Used today for solo dogfooding and a small invite-only tester pool.
Expect occasional restarts and feature churn — this is the developer-facing surface, not a production SLA endpoint.

The corresponding API runs at api.paperstox.in (HTTPS, audited per the platform's internal compliance posture).
