ATM-based
Buys the at-the-money strike for the current index price. Set an ATM gap to go one or more strikes ITM or OTM.
Options automation
Your strategy runs on the Nifty, Bank Nifty or stock chart. The JSON Bridge turns each buy or sell signal into the right option contract – at the money, by premium or by exact symbol – places it with your broker, and exits on the opposite signal.
Signal BUY · ATM strike for spot 25,012 → 25000 CE
Strike selection
Buys the at-the-money strike for the current index price. Set an ATM gap to go one or more strikes ITM or OTM.
Enter a target premium, say ₹100, and a max variation, say ₹20. The bridge picks the strike whose premium is closest – for example 22500 CE at ₹98.
Name the exact contract when your strategy already knows which strike it wants.
| Option chain (example) | Premium | Premium-based pick (target ₹100, max ±₹20) |
|---|---|---|
| 22400 CE | ₹135 | Outside range |
| 22450 CE | ₹112 | In range |
| 22500 CE | ₹98 | Selected – closest to ₹100 |
| 22550 CE | ₹75 | Outside range |

Both connect TradingView indicators or strategies to your broker. Custom Bridge is the simplest to set up. JSON Bridge adds script-specific orders, target, stop-loss, trailing stop-loss, rollover, option strike selection and exit on opposite, and it can be called from Python or any code.
Use bar-close alerts in Pine Script, use strategy alerts with position size, and turn on exit on opposite in the JSON Bridge so a repeated signal does not stack positions. You can also pause a bridge without deleting it.
Yes. Generate the JSON syntax in the JSON Bridge and POST it to your bridge webhook URL from Python whenever your strategy gives a buy or sell signal. The same works from Node.js, Excel macros, Telegram bots or any tool that can send an HTTP request.
Yes. Any TradingView indicator that can fire an alert works. Create the alert on the index chart, paste the JSON Bridge webhook and message, and the bridge picks the option strike by your ATM, premium or symbol rule.
No. AlgoDelta does not give trading calls or recommendations. The bridge only executes the selection rule you configure on the signal you send.
