Place a CNC market BUY order

The simplest possible live order: buy equity for delivery, at whatever price the market gives you right now.

order_id = kite.place_order(
    variety="regular",
    exchange="NSE",
    tradingsymbol="INFY",
    transaction_type="BUY",
    quantity=1,
    product="CNC",
    order_type="MARKET",
    validity="DAY",
)
print("Order placed:", order_id)

Before running this against real money

1. Check funds first (chapter 12) — a market order can fill at a price higher than the last-seen LTP if the market has moved or the spread is wide; don't size to exactly your available cash.
2. Check the order book (chapter 18) a few seconds after placing, to confirm status: COMPLETE rather than assuming success from the order_id response.
3. Start with quantity=1 on a liquid large-cap when testing this for the first time — the point is to verify the plumbing works, not to take a real position size.

def safe_market_buy(kite, exchange: str, symbol: str, qty: int) -> str:
    available = kite.margins(segment="equity")["available"]["cash"]
    ltp = kite.ltp([f"{exchange}:{symbol}"])[f"{exchange}:{symbol}"]["last_price"]
    if ltp * qty * 1.02 > available:   # 2% buffer for price movement
        raise RuntimeError("Insufficient margin with safety buffer")
    return kite.place_order(
        variety="regular", exchange=exchange, tradingsymbol=symbol,
        transaction_type="BUY", quantity=qty, product="CNC",
        order_type="MARKET", validity="DAY",
    )

Why MARKET orders are risky on anything illiquid

A market order has no price limit — it fills at whatever the exchange matches it against, walking through the order book (chapter 26) until fully filled. On a thinly-traded stock this can mean a materially worse average price than the LTP you saw a second ago. Reserve market orders for liquid instruments where you're confident the spread is tight; use limit orders (chapter 46) otherwise.
