api.place_order(buy_or_sell='B',
                        product_type='C',
                        exchange=exchange,
                        tradingsymbol=symbol,
                        quantity=10 ,
                        discloseqty=qty,
                        price_type='LMT',

order_book = api.get_order_book()
buy_all_order_dict = [d for d in order_book if d.get('status') == 'OPEN' and d.get('trantype') == 'B']
buy_order_dict = next((d for d in buy_all_order_dict if d.get('tsym') == symbol), None)

api.modify_order(
                orderno = buy_order_dict['norenordno'],
                exchange = exchange,
                tradingsymbol = symbol,
                newquantity = 10,
