How do I buy an option?

being

I have the backend calculations code ready but I am not sure how to buy an option. I tried "BANKNIFTY2372044800PE" as an instrument name but no luck. Any help please?

Go through the order placement APIs here.

def placeBNOrder(symbol, buy_sell, quantity, sl_price):
# Place an intraday market order on NSE
if buy_sell == "buy":
t_type = kite.TRANSACTION_TYPE_BUY
t_type_sl = kite.TRANSACTION_TYPE_SELL
elif buy_sell == "sell":
t_type = kite.TRANSACTION_TYPE_SELL
t_type_sl = kite.TRANSACTION_TYPE_BUY

# Place the market order
market_order = kite.place_order(
tradingsymbol=symbol,
exchange=kite.EXCHANGE_NFO,
transaction_type=t_type,
quantity=quantity,
order_type=kite.ORDER_TYPE_MARKET,
product=kite.PRODUCT_MIS,
variety=kite.VARIETY_REGULAR
)

# Wait for the market order to complete
a = 0
while a < 10:
try:
order_list = kite.orders()
break
except:
print("Can't get orders..retrying")
a += 1

# Check if the market order is complete
market_order_status = None
for order in order_list:
if order["order_id"] == market_order:
market_order_status = order["status"]
break

# If the market order is complete, place the SL order
if market_order_status == "COMPLETE":
try:
kite.place_order(
tradingsymbol=symbol,
exchange=kite.EXCHANGE_NFO,
transaction_type=t_type_sl,
quantity=quantity,
order_type=kite.ORDER_TYPE_LIMIT,
trigger_price=sl_price,
price=sl_price,
product=kite.PRODUCT_MIS,
variety=kite.VARIETY_REGULAR
)
except Exception as e:
print(f'Error placing SL for addon position for {symbol}, SL to be set {sl_price}.')
print(e)
else:
kite.cancel_order(order_id=market_order, variety=kite.VARIETY_REGULAR)

Using this to place order but as soon it triggers it also triggers the sell side and basically buy and then immediately exits it. What could be the issue here? @rakeshr
