Project description:
"I need a production-grade web platform that mirrors Algotest’s Time-Based Strategy Maker—nothing to do with indicator-driven logic—so that my users can design, test, and execute multi-leg F&O trades strictly by the clock. A typical workflow should let them set rules such as “enter at 09:20, exit at 15:20, square-off on weekly expiry,” then back-test those rules on historical data, forward-test in paper mode, and finally deploy live.

Broker connectivity is critical. Please prioritise native, stable API integrations for Alice Blue, ICICI Direct, and Kotak Neo first; the architecture must remain open so we can plug in Zerodha, Angel One, Upstox, Dhan, Fyers, and 5paisa later without rewrites.

Key functional blocks I’m expecting you to deliver:

• Strategy builder with time triggers, multi-leg support, and margin/lot size validation in real time
• Historical back-testing engine (minute-level data accuracy) producing P&L, draw-down, and leg-wise attribution reports
• Paper-trade forward tester that mimics live trading latency
• Live execution module with risk controls—global loss cap, kill-switch, order reconciliation, and automatic re-entry handling
• Razorpay checkout flow with GST-ready invoices, subscription renewal, and full user/billing management
• Admin console for user support, refunds, strategy moderation, and system health metrics
• Security baseline: 2FA for every sign-in, vaulted secrets for API keys, data encryption at rest and in transit, and immutable audit logs
• Cloud-native infra that auto-scales, rolls out blue-green deployments, and ships with complete Terraform/Ansible (or similar) scripts so I can recreate every layer independently
• Clean hand-over: documented source code, infra state files, and all credentials

Acceptance criteria: a user should be able to register, pay, build a simple 09:20 straddle, back-test last one year, run a paper trade for a day, switch to live on Alice Blue, and obtain a downloadable PDF report—without my intervention.

If you have already built similar algo-trading or broker-API work, point me to a demo or repo so I can evaluate your approach to latency, reconciliation, and error handling. I’ll favour developers who can share a concise project plan and propose realistic sprints for the phased roll-out above." (client-provided description)
