How to Subscribe to a Symbol and Receive Quotes in the Absence of Open Positions?

[FxMathSolution]

In the context of algorithmic trading, I've noticed that I receive a 'Symbol not Subscribed' alert when attempting to get quotes for a specific symbol (e.g., EURUSD) when there are no open positions for that pair. Is there a way to subscribe to a symbol and receive quotes even in the absence of open positions? What approach should be taken to ensure the availability of quotes for any given symbol?

I just testing this example:

api = Ctrader(server,account,password)
time.sleep(3)

checkConnection = api.isconnected()
print("Is Connected?: ", checkConnection)
time.sleep(1)

api.subscribe("EURUSD", "GBPUSD")


quote = api.quote()
print(quote)

# Buy position
price = api.quote()
price = price['EURUSD']['bid'] 

symbol = "EURUSD"
volume = 0.01 # position size:
stoploss =  round(price - 0.00010,6)
takeprofit = round(price + 0.00010,6)

id = api.buy(symbol, volume, stoploss, takeprofit)
print(f"Position: {id}")

# sell position 
price = api.quote()
price = price['EURUSD']['bid'] 

symbol = "EURUSD"
volume = 0.01 # position size
stoploss =  round(price + 0.00010,6)
takeprofit = round(price - 0.00010,6)

id = api.sell(symbol, volume, stoploss, takeprofit)
print(f"Position: {id}")

I fixed it. Add a sleep here:

api.subscribe("EURUSD", "GBPUSD")
time.sleep(1)
