| # Selva Option Backtest — Real ICICI Direct Breeze Data |
|
|
| This version is a Hugging Face Docker Space using a Node.js/Express backend. |
|
|
| ## What it does |
|
|
| - Connects to ICICI Direct Breeze using the API session entered in the browser. |
| - Keeps `BREEZE_API_SECRET` server-side. |
| - Fetches real NIFTY 1-minute historical candles. |
| - Fetches real NIFTY option 1-minute historical candles. |
| - Runs the overnight ATM CE + PE backtest on the server. |
| - No simulated market prices are used by the backtest. |
| - Exports trade and daily results as CSV. |
|
|
| ## Hugging Face Secrets |
|
|
| In Space Settings -> Secrets and Variables, add: |
|
|
| - `BREEZE_API_KEY` |
| - `BREEZE_API_SECRET` |
|
|
| Do NOT put the secret in `index.html`, `main.js`, or commit it to Git. |
|
|
| ## Breeze session |
|
|
| Click the ICICI Direct login link shown by the app, complete the login/authorization flow, copy the API session value, and paste it into the app. |
|
|
| The API session is kept only in the running server process and is not written to disk. |
|
|
| ## Strategy |
|
|
| The UI keeps the original strategy structure: |
|
|
| - Entry: 15:15 |
| - Entry days: Monday to Thursday |
| - Buy ATM CE + ATM PE |
| - ATM step: 50 |
| - Hold overnight |
| - Next trading day: SL checked before target |
| - Default square-off: 15:10 |
| - Default target: 20 points |
| - Default SL: 10 points |
| - Default brokerage: ₹40 per leg |
| - Quantity: 65 |
|
|
| Important: the weekday expiry mapping is retained from the supplied strategy. For historical periods that cross changes in the NIFTY weekly-expiry calendar or exchange holidays, verify the expiry calendar before using results for trading decisions. |
|
|
