ASSISTANT (hermes, claude-haiku-4.5)
I don't have immediate context about which two trading bots you're referring to. Let me search my past conversations to see if we've been working on comparing trading bots.

ASSISTANT (hermes, claude-haiku-4.5)
Yes! I found it. We were comparing the three trading bot brokers on your VPS this morning. The main comparison was **Kotak vs. Shoonya/Flattrade** — and I identified some critical differences.
Here's the quick recap:
**5 Critical Differences Found:**
1. **Authentication** — Kotak uses two-step (mobile + TOTP + MPIN), while Shoonya/Flattrade use simple API tokens
2. **JSON Response Format** — Kotak wraps responses in `{"stat": "ok/not_ok", "data": {...}}`, others return direct responses. **Active bug found** at line 28 of order_data.py (KeyError 'data')
3. **Token Field Name** — Kotak uses `"tok"`, others use `"token"`
4. **WebSocket** — Kotak uses proprietary 54KB binary library (HSWebSocketLib), others use standard WebSocket
5. **Nginx SSL Config** — Kotak has SSL directives in wrong order (after location blocks instead of before)
I also found that your trading bots (claude_bot and lt_3candle_bot) are currently only connected to Shoonya and Flattrade — they skip Kotak entirely because of these stability issues.
The detailed findings are saved in `/home/ubuntu/docs/KOTAK-CRITICAL-DIFFERENCES.md` and in my session memory.
Do you want me to dive deeper into any of these differences, or help fix the active bugs I found?

## Overview
OpenAlgo is a production-ready algorithmic trading platform built with Flask (backend) and React 19 (frontend). It provides a unified API layer across 24+ Indian brokers, enabling seamless integration with TradingView, Amibroker, Excel, Python, and AI agents.
**Repository**: https://github.com/marketcalls/openalgo
**Documentation**: https://docs.openalgo.in
## Development Environment Setup
### Prerequisites
- Python 3.12+ (required per pyproject.toml)
- Node.js 20+ for root-level CSS compilation
- Node.js 20/22/24 for React frontend development
- **uv package manager (required)** - Never use global Python
### Initial Setup

## Application Architecture
### Dual Frontend System
OpenAlgo has TWO frontend systems that coexist:
1. **Jinja2 Templates** (`/templates/`, `/static/`): Traditional Flask templates with Tailwind CSS 4 + DaisyUI
2. **React 19 Frontend** (`/frontend/`): Modern SPA with TypeScript, Vite, shadcn/ui, TanStack Query
Both frontends are served by the same Flask application. The React frontend is built and served from `/frontend/dist/`.
### Backend Structure
- `app.py` - Main Flask application entry point
- `blueprints/` - Flask route handlers (UI and webhooks)
- `restx_api/`

Perfect! Now let me give you a clean summary:
---
## HISTORICAL DATA FETCHING: Complete Breakdown
### **SHOONYA** ✅ Full Support
- **Daily Data**: `/NorenWClientAPI/EODChartData` endpoint
- **Intraday**: `/NorenWClientAPI/TPSeries` endpoint
- **Intervals**: 1m, 3m, 5m, 10m, 15m, 30m, 1h, 2h, 4h, D (10 options)
- **Response**: Direct array/dict with fields (into, inth, intl, intc, intv, oi)
- **Timestamp**: Epoch for daily, string "DD-MM-YYYY HH:MM:SS" for intraday
---
### **FLATTRADE** ✅ Full Support
- **Daily Data**: `/EODChartData` endpoint
- **Intraday**: `/TPSeries` endpoint
- **Intervals**: 1m, 5m, 15m, 30m, 1h, D (6 options - fewer than Shoonya)
- **Response**: Same structure as Shoonya (into, inth, intl, intc, intv, oi)
- **Timestamp**: Same format as Shoonya
**Key Difference from Shoonya**: Endpoint paths shorter, fewer interval options
---
### **KOTAK** ❌ NO Support (Broker API Limitation)
- **Daily Data**: NONE - `get_history()` returns empty DataFrame
- **Intraday**: NONE - `get_supported_intervals()` returns empty dict
- **Status**: Stub implementation at lines 546-565 of `kotak/api/data.py`
- **Impact**:
- Cannot backtest strategies
- Cannot build SMMA, RSI, VIDYA indicators
- Only viable for live execution of pre-built strategies
---
## Why This Matters for Your Bots
**claude_bot** (SMMA / 2RSI) ← Needs historical data for SMMA calculation
**lt_3candle_bot** (Renko/VIDYA) ← Needs historical data for Renko/VIDYA calculation
Both only work on **Shoonya + Flattrade**, NOT Kotak.

I've saved the full technical analysis to `/home/ubuntu/docs/HISTORICAL-DATA-COMPARISON.md` with code references, endpoint details, and field mappings.

Let me check the Nginx config for Shoonya specifically:
The Nginx config looks correct. The issue is that the Gunicorn socket should be receiving the connection. Let me check if the Gunicorn process is actually listening:

## Summary
**Issue**: https://shoonya.openalgo.theworkpc.com/ was timing out
**Root Cause**:
- Gunicorn process was running but had stale connections
- Shoonya broker API session expired (Session Key invalid)
- Socket became unresponsive even though process was still alive
- Nginx couldn't proxy through the socket → timeout
**Fix Applied**:
```
sudo systemctl restart openalgo-shoonya-openalgo.theworkpc.com-shoonya.service
```
**Result**: ✅ Now Working!
- Shoonya: https://shoonya.openalgo.theworkpc.com/
- Flattrade: https://flattrade.openalgo.theworkpc.com/
- Kotak: https://kotak.openalgo.theworkpc.com/
This is a common issue with long-running services. I've documented it in `/home/ubuntu/docs/SHOONYA-SERVICE-DOWNTIME-REPORT.md` with prevention recommendations (health checks + automated restarts).
