EA - Minimum time unit for MT5 updates and/or MT5 EA

 

I would like to pay to have a MT5 EA coded for me but I need to know that it will use the minimum time unit that MQL5 or any other MT5 EA coding service can use to record price movement/place trades in. Does anyone know the minimum time unit that MT5 updates in and/or the minimum time unit that a MT5 EA can record price movement/place trades in?
