How to Build a Nifty Option Buying Bot in Python (With Logic)

Option Buying Bot - Core Logic

Most retail traders lose in option buying because they buy random strikes. A bot only buys when conditions match. Here is a simple but effective logic we teach:

The Setup

Instrument: NIFTY Spot

Timeframe: 5 min

Indicators: 20 EMA, 50 EMA, VWAP, RSI

Buy Condition (CE)

• Price is above VWAP


• 20 EMA > 50 EMA


• RSI > 55 and < 75 (avoid overbought)


• Candle closes above previous swing high

Entry Logic Code

if price > vwap and ema20 > ema50 and 55 < rsi < 75:
    buy_ce = True
    strike = atm_strike + 100  Slight OTM for momentum
    place_order(symbol=strike, qty=50, sl=30%, target=80%)

Risk Management

We never risk more than 1.5% per trade. If capital is 1 Lakh, max loss per trade is Rs 1500. Bot auto-squares off at 3:15 PM.

Backtest result: This simple setup gave 58% win rate with 1:1.8 Risk:Reward in last 6 months on NIFTY.

How to Deploy?

Use AliceBlue API or Zerodha Kite Connect. Host on AWS or local system with websocket for live prices.
