Real integration notes for wiring NIFTY ML models to live broker data via Dhan. Research/

paper-trading context — not a live-trading recommendation.

Dhan's API exposes direct option-chain access — exactly what an options-ML system needs:

`POST /optionchain`

— full chain for an underlying`POST /optionchain/expirylist`

— available expiries`security_id`

, `last_price`

, `volume`

, `oi`

, `previous_oi`

, `implied_volatility`

,
`top_bid_price`

, `top_ask_price`

, and greeks (delta/theta/gamma/vega)Security IDs are stable: **NIFTY = 13 (IDX_I)**, **BANKNIFTY = 10001 (IDX_I)**.

A research dashboard pulls live chain + underlying, runs the trained XGBoost model on each

new 15-minute bar, and displays:

Keep the **inference path separate from the execution path**. The dashboard shows; a

permissioned, human-approved module places orders.

The `DhanLiveTrader`

pattern: load the model, predict on each new bar, place long orders with

configurable SL/TP (default 1.0 ATR SL, 2.0 ATR TP), and **run in paper mode first**. Only

after stable out-of-sample + paper evidence should any execution module even be considered.

```
{
  "client_id": "YOUR_DHAN_CLIENT_ID",
  "access_token": "YOUR_DHAN_ACCESS_TOKEN",
  "is_paper_trade": true,
  "nifty_symbol": "NIFTY",
  "quantity": 50,
  "max_trades_per_day": 3,
  "sl_atr_mult": 1.0,
  "tp_atr_mult": 2.0
}
```

A known footgun: using a Stop-Loss *Limit* (SL-L) order with `price = sl − 0.05`

means it

won't fill if price crashes through the stop. Prefer SL-Market for the protective stop.

Execution quality is its own research topic — don't bolt it on at the end.

The ML side of this stack showed real directional skill (60.5% top-decile accuracy) but the

fixed-SL backtest was still unprofitable (PF 0.53). A dashboard that displays an honest

"RESEARCH / PAPER" status is worth more than one that hides the gap.

*Research only. Not investment advice. SEBI/compliance is a separate, required topic before live trading.*
