Hi,

ich habe folgendes Script im Netz gefunden und es etwas an meine Bedürfnisse angepasst. Die Funktion ist soweit Ok allerdings möchte ich das ein Alarm nur einmal ausgeführt wird. Wie läßt sich das einstellen ?

#property indicator_chart_window
extern string TLineName1="TL1";
extern string TLineName2="TL2";
extern color LineColor=Red; 
extern color LineColor2=Green; 
extern int LineStyle=STYLE_SOLID;
extern int AlertPipRange=5;
extern string AlertWav="alert.wav";

  }

   int    counted_bars=IndicatorCounted();

      ObjectSet(TLineName1, OBJPROP_COLOR, LineColor);

      double val=ObjectGetValueByShift(TLineName1, 0);
 
      if (Bid-AlertPipRange*Point <= val && Bid+AlertPipRange*Point >= val) Alert( Symbol()," Price at Level TL1");
