I used this code: balance_info = client.balance()

usdt_balance = None

for balance in balance_info:
    if balance['asset'] == 'USDT':
        usdt_balance = balance['balance'] 

def get_quantity(symbol, usdt_balance):
    try:
        mark_price_data = client.ticker_price(symbol=symbol)
        mark_price = float(mark_price_data['price']) if 'price' in mark_price_data else 0.0

        token_price = mark_price
        margin = 50
        quantity = round(float(usdt_balance) * margin / token_price, 2)
        return quantity
    except BinanceAPIException as e:
        print("Error executing long order:")
        
print(get_quantity(symbol, usdt_balance))

while True:
    lookback = 10080
    interval = '1m'
    df = get_klines(symbol, interval, lookback)

    if df is not None:
        signals = signal_generator(df)
        order_quantity = get_quantity(symbol, usdt_balance)
        mark_price_data = client.ticker_price(symbol=symbol)
        mark_price = float(mark_price_data['price']) if 'price' in mark_price_data else 0.0
        print(f"The signal time is: {dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S')} Price: [{mark_price}] - Signals: {signals}")

    if signals == ['buy']:
        try:
            order = client.new_order(symbol=symbol, side='BUY', type='MARKET', quantity=order_quantity)
            print("Long order executed!")

        except BinanceAPIException as e:
            print("Error executing long order:")

        time.sleep(1)

    if signals == ['sell']:
        try:
            order = client.new_order(symbol=symbol, side='SELL', type='MARKET', quantity=order_quantity)
            print("Short order executed!")

        except BinanceAPIException as e:
            print("Error executing short order:")

        time.sleep(1)

    time.sleep(1)
But I getting ERROR:Connected to the Binance API.
