Erstellen eines Signals

Programming a signal to be output when two different (I call in the specification of requirements) line indicators in opposite directions in a period. The signal should consist of arrows in the chart, acoustically as well as indicating the assets in the popup window. The distance of the arrows to the candle must be adjustable, to the direct touch up. All setting options of the indicators must be retained. The arrow should appear in case the price falls below the candle pointing upwards and in case the price rises above the candle it should appear pointing downwards. The order is for the Metatrader 5.
