Request for Quotation (RFQ) + Statement of Work (SoW) Project Title High-End Multi-Horizon Algo Trading System with Intraday Scalping Bot + Long-Term CNC Dashboard (SEBI-Compliant, Zerodha Integration) Background We are seeking an experienced Algo Trading Developer/Quant Engineer (preferably India/Kolkata based, remote considered) to build and deliver a production-grade trading system integrated with Zerodha Kite Connect API. The system must include: Intraday Scalping Bot (1/2/5-minute intervals) with regime-based logic, ML enhancements, latency measurement, and SEBI compliance. Long-Term CNC Dashboard for positional/swing trades, with portfolio analytics, trade journaling, and monitoring. The deliverable must be fully tested, hardened, SEBI-compliant, and deployment-ready, with detailed documentation and training. Budget 100000.00 Location Preferably Kolkata Scope of Work (SoW) Part A – Intraday Scalping Bot Core Strategy Regime detector: Momentum: price > VWAP, EMA20>EMA50, VWAP slope >0. Reversion: weak trend, price stretched from VWAP/BB ≥ k×ATR. Neutral: no trade. Entries: ATR, VWAP, RSI(7), BB(20,2), EMA cross, volume z-score. Exits: ATR-based TP/SL, VWAP cross, time-stop (3–4 bars). Risk: 0.25–0.5% equity per trade, max 3 attempts/symbol/day, daily loss cap (−2%). Coverage: ≤10 liquid NSE stocks. ML Layer (prediction enhancement) Models: Logistic regression / Gradient Boosting (explainable ML). Features: VWAP distance, RSI, ATR, BB width, volume z-score, spread, sector-relative. Training: Purged walk-forward CV, rolling OOS validation. Output: Probability score to filter/weight trades. Deliver: Training script, saved model, explainability (SHAP/feature importance). Latency Optimization & Metrics Log & monitor: T1 = Data latency T2 = Decision latency T3 = Order ACK latency T4 = Fill latency Report P50/P90/P99 latencies + slippage (ticks). Infrastructure: Mumbai-region VPS, async I/O, marketable-limit orders with spread filter. Compliance Algo ID tagging on every order. Audit logs: features, signals, scores, orders, fills, P&L, parameter changes. Manual + automatic kill-switch. Runbook for SEBI audit readiness. Testing Backtester with Indian costs (brokerage, STT/CTT, SEBI charges, stamp, GST). Realistic slippage model (≥1 tick). Rolling walk-forward: train 6 weeks → test 2 weeks, rolling 12+ months. Reports: PF ≥1.2, win% 45–60%, Avg Win/Loss ≥1.1, Max DD <8%, t-stat >2.0. Paper Trading 2–3 weeks live run (mock orders). Logs must match OOS backtest within ±20%. Deployment Docker/systemd service on VPS. Auto-restart, graceful shutdown (flatten first). Logging + alerts (Telegram/Slack: fills, P&L, errors, kill-switch). Part B – Long-Term CNC Dashboard Trade Execution Manual/semi-auto order input (Zerodha Kite). Tag trades as CNC (cash & carry). Dashboard Features Portfolio snapshot (holdings, average cost, MTM, realized/unrealized P&L). Strategy-based trade signals (e.g., EMA crossovers, RSI swing filters). Watchlist with signals/alerts. Journal: Auto-log entry/exit reason, trade duration, outcome. Charts: Annotated trade entry/exit on OHLCV. Risk & Compliance Exposure summary by stock/sector. Portfolio-level stop-loss alerts.

Deliverables Source code (Git repo): structured, documented, reproducible. Backtest & walk-forward reports (PDF/Notebook). Paper-trading logs (2–3 weeks). Latency metrics report. Deployment package (Docker/systemd + runbook). Algo ID approval evidence. CNC dashboard (web/app) with reports. Documentation: README, setup guide, user runbook. Training session for handover. Milestones & Payment M1 (10%): Core skeleton + regime logic. M2 (15%): Zerodha integration + risk + compliance skeleton. M3 (15%): ML layer + backtest engine. M4 (15%): Walk-forward reports delivered. M5 (25%): Paper trading results + latency metrics. M6 (20%): CNC dashboard + deployment + handover. Acceptance Criteria Walk-forward PF ≥1.2, Max DD <8%, t-stat >2.0. Latency logs available, P99 order ACK <500 ms. Paper-trading stats close to OOS (±20%). Algo ID tagged orders, complete audit logs.

Dear Babu B., I'm excited to present this proposal for your 'Scalper MVP Enhancement & Zerodha Integration' project. I've thoroughly reviewed your detailed RFQ, including the existing scaffold and the critical enhancements required for live Zerodha integration, UI finalization with live charts, and robust operational readiness. My expertise in developing high-performance trading systems, integrating with broker APIs like Zerodha Kite Connect, implementing secure and idempotent order execution, and crafting comprehensive risk management layers aligns perfectly with your vision. I am proficient in Node.js, Python, PHP, and databases, along with setting up scalable and monitored deployments. My approach will focus on a phased integration: first, replacing mocks with live Zerodha data and order execution, then hardening the code, implementing the essential risk and compliance features (including SEBI Algo ID and kill-switches), and finally establishing a rigorous backtesting and paper trading framework for verification. We'll ensure the WP UI provides intuitive control and real-time insights. I'm confident I can transform your MVP into a production-ready, reliable, and compliant scalping assistant. I look forward to discussing how we can achieve your project goals together. Sincerely, Navneet

Hello [Client Name], I’m Arun, a full-stack developer with 14+ years of experience in trading systems, APIs, and financial platforms. I’ve worked extensively with Zerodha Kite Connect, Node.js, Python, and WordPress, making me well-positioned to finalize your semi-autonomous scalper MVP. Approach: Zerodha Integration: Replace mock tick feeds with live Kite subscriptions (ticks + OHLC) and implement secure token handling with TTL refresh. Order Execution: Build robust MIS scalp execution (place/modify/cancel), retries/backoff, and broker code mapping. Signal Engine Upgrades: Integrate NewsAPI/Benzinga feeds, add NLP sentiment scoring, and extend backtesting with Sharpe, MDD, slippage-adjusted P&L. Risk & Monitoring: Daily loss caps, NSE session rules, latency dashboards, audit logs. UI Finalization: Keep TradingView embed, map Zerodha symbols, enable push-based updates for real-time signals and annotations. Questions: Do you already have Zerodha API credentials/sandbox access available? Should we prioritize real-time order execution stability before sentiment integration? Do you prefer Grafana/Prometheus for monitoring, or lightweight in-app dashboards? Happy to connect on a quick call via Freelancer to align priorities and deliverables. Best regards, Arun

With an expertise spanning 9 years in the software industry, I am confident in my ability to successfully integrate and enhance your Scalper MVP with Zerodha and APIs. My skills in API Integration, JavaScript, Node.js, Python, WordPress especially come to the fore here. In addition, my proficiency in Flask for handling secure tokens and Django Rest Framework for real-time data processing will be invaluable in dealing with the complexities of real-time stock market data. I have extensively worked on similar projects involving financial markets and risk management domains. My understanding of brokerage codes mapping, risk mitigation via spread/slippage filters, and trading windows at exchanges, are some examples that demonstrate my familiarity with the domain-specific challenges. Moreover, I deeply appreciate your system's human-in-the-loop design and fully appreciate the importance of a smooth user interface. I'm comfortable with bringing together various aspects into a coherent whole - incorporating live charts using TradingView embeds, integrating external feeds like NewsAPI for NLP based confidence computation into my Python Signal Engine and intricate database setups which include Postgres as well.I’m not merely looking for a one-off transactional experience; rather I thrive on building long-term partnerships. Let's collaborate and build something amazing together!
