Saved other stock data into GOOG.CSV file. However results are showing for Previously saved GOOG data

Is there any bug in the code? I want to back test for 100 stocks but, for every data I am getting the same results which was displayed in the website. Please help me to resolve this

I have saved reliance data in GOOG.csv in the test folder.

!pip install backtesting
from pandas_datareader import data as pdr
import pandas as pd
import numpy as np
import yfinance as yf
import seaborn as sns
import matplotlib.pyplot as plt

tickers = pd.read_html('https://ournifty.com/stock-list-in-nse-fo-futures-and-options.html#:~:text=NSE%20F%26O%20Stock%20List%3A%20%20%20%20SL,%20%201000%20%2052%20more%20rows%20')[0]
tickers = tickers.SYMBOL.to_list()

for count in range(len(tickers)):
tickers[count] = tickers[count] + ".NS"

def MovingAverageCrossStrategy(stock_symbol = 'ULTRACEMCO.NS', start_date = '2010-01-01', short_window = 20, long_window = 50):
data = pdr.get_data_yahoo(stock_symbol, start = start_date)
return data

for symbol in tickers:

try:

data = MovingAverageCrossStrategy("RELIANCE.NS", '2000-01-01', short_window = 10, long_window = 20)
data.to_csv("D:/trading_backtesting/backtesting.py-master/backtesting/test/GOOG.csv")

from backtesting import Backtest, Strategy
from backtesting.lib import crossover

from backtesting.test import SMA, GOOG

class SmaCross(Strategy):
n1 = 10
n2 = 20

def init(self):
    close = self.data.Close
    self.sma1 = self.I(SMA, close, self.n1)
    self.sma2 = self.I(SMA, close, self.n2)

def next(self):
    if crossover(self.sma1, self.sma2):
        self.buy()
    elif crossover(self.sma2, self.sma1):
        self.sell()

bt = Backtest(GOOG, SmaCross,
cash=10000, commission=.002,
exclusive_orders=True)

output = bt.run()
bt.plot()
print(output)
