BrainTrend1Sig_Alert is a powerful semaphore signal indicator for MetaTrader 5 that comes packed with alerts, email notifications, and push messages to keep you in the loop.
Here’s a quick rundown of the recent updates made to the indicator to enhance its functionality:
- New input parameters have been added:
input uint NumberofBar=1;//Bar number for the signal input bool SoundON=true; //Enable alerts input uint NumberofAlerts=2;//Number of alerts input bool EMailON=false; //Enable mailing the signal input bool PushON=false; //Enable sending the signal to mobile devices
- Three new functions have been added to the end of the indicator code: BuySignal(), SellSignal(), and GetStringTimeframe():
//+------------------------------------------------------------------+ //| Buy signal function | //+------------------------------------------------------------------+ void BuySignal(string SignalSirname, // text of the indicator name for email and push messages double &BuyArrow[], // indicator buffer with buy signals const int Rates_total, // the current number of bars const int Prev_calculated, // the number of bars on the previous tick const double &Close[], // close price const int &Spread[]) // spread { //--- static uint counter=0; if(Rates_total!=Prev_calculated) counter=0; bool BuySignal=false; bool SeriesTest=ArrayGetAsSeries(BuyArrow); int index; if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; if(NormalizeDouble(BuyArrow[index],_Digits) && BuyArrow[index]!=EMPTY_VALUE) BuySignal=true; if(BuySignal && counter<=NumberofAlerts) { counter++; MqlDateTime tm; TimeToStruct(TimeCurrent(),tm); string text=TimeToString(TimeCurrent(),TIME_DATE)+" "+string(tm.hour)+":"+string(tm.min); SeriesTest=ArrayGetAsSeries(Close); if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; double Ask=Close[index]; double Bid=Close[index]; SeriesTest=ArrayGetAsSeries(Spread); if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; Bid+=Spread[index]; string sAsk=DoubleToString(Ask,_Digits); string sBid=DoubleToString(Bid,_Digits); string sPeriod=GetStringTimeframe(ChartPeriod()); if(SoundON) Alert("BUY signal \n Ask=",Ask,"\n Bid=",Bid,"\n currtime=",text,"\n Symbol=",Symbol()," Period=",sPeriod); if(EMailON) SendMail(SignalSirname+": BUY signal alert","BUY signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod); if(PushON) SendNotification(SignalSirname+": BUY signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod); } //--- } //+------------------------------------------------------------------+ //| Sell signal function | //+------------------------------------------------------------------+ void SellSignal(string SignalSirname, // text of the indicator name for email and push messages double &SellArrow[], // indicator buffer with sell signals const int Rates_total, // the current number of bars const int Prev_calculated, // the number of bars on the previous tick const double &Close[], // close price const int &Spread[]) // spread { //--- static uint counter=0; if(Rates_total!=Prev_calculated) counter=0; bool SellSignal=false; bool SeriesTest=ArrayGetAsSeries(SellArrow); int index; if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; if(NormalizeDouble(SellArrow[index],_Digits) && SellArrow[index]!=EMPTY_VALUE) SellSignal=true; if(SellSignal && counter<=NumberofAlerts) { counter++; MqlDateTime tm; TimeToStruct(TimeCurrent(),tm); string text=TimeToString(TimeCurrent(),TIME_DATE)+" "+string(tm.hour)+":"+string(tm.min); SeriesTest=ArrayGetAsSeries(Close); if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; double Ask=Close[index]; double Bid=Close[index]; SeriesTest=ArrayGetAsSeries(Spread); if(SeriesTest) index=int(NumberofBar); else index=Rates_total-int(NumberofBar)-1; Bid+=Spread[index]; string sAsk=DoubleToString(Ask,_Digits); string sBid=DoubleToString(Bid,_Digits); string sPeriod=GetStringTimeframe(ChartPeriod()); if(SoundON) Alert("SELL signal \n Ask=",Ask,"\n Bid=",Bid,"\n currtime=",text,"\n Symbol=",Symbol()," Period=",sPeriod); if(EMailON) SendMail(SignalSirname+": SELL signal alert","SELL signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod); if(PushON) SendNotification(SignalSirname+": SELL signal at Ask="+sAsk+", Bid="+sBid+", Date="+text+" Symbol="+Symbol()+" Period="+sPeriod); } //--- } //+------------------------------------------------------------------+ //| Getting the timeframe as a string | //+------------------------------------------------------------------+ string GetStringTimeframe(ENUM_TIMEFRAMES timeframe) { //---- return(StringSubstr(EnumToString(timeframe),7,-1)); //---- }
- Added calls to the BuySignal() and SellSignal() functions after the indicator calculation cycles in the OnCalculate() block://---
BuySignal("BrainTrend1Sig_Alert",BuyBuffer,rates_total,prev_calculated,close,spread);
SellSignal("BrainTrend1Sig_Alert",SellBuffer,rates_total,prev_calculated,close,spread);
//---Note that BuyBuffer and SellBuffer are the names of the indicator buffers responsible for storing the buy and sell signals. It’s essential to set either zeros or EMPTY_VALUE in the indicator buffers as the empty values.
Keep in mind that you should call the BuySignal() and SellSignal() functions only once in the OnCalculate() block of the indicator code.
