On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

On MT5: Unless the chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.
