One Alert per signal not once every bar
Once alert per bar can have only one alert per bar, and thus also only once alert per signal.
Where once alert per signal can have multiple alerts per bar, because there can be more then once signal in a bar.
You have to define signal every time, or signal oscillator, called flip/flop it's one alert for high then one alert for low and etc.
if(signal==1) { Alert(); signal=0; } else if(signal==0) { Alert(); signal=1; }
if(iTime(Symbol(),0,0)!=0){ //Very strange as it will always !=0 unless there is no history loaded Alert(); iTime(Symbol(),0,0)=0; //No idea what you are trying to do here. This will not compile. }

Don't alert on a signal, alert on a change in signal
static bool isSignal=true; bool wasSignal = isSignal; isSignal = ...; if(isSignal && !wasSignal) Alert(...);

Don't alert on a signal, alert on a change in signal
Like there are some indicator that alert on cross which is easy to logically code.
i am having issue with some signal indicator not the one on
if(A cross B) Alert();
if i place it on M30 it alerts me every 30 minutes on the same signal.
it actually alerts once on every new bar formation.
int flagval1 = 0; int flagval2 = 0; double tmp=0; for (shift = CountBars; shift>=0; shift--) { if (.....signal condition is true....) { if (shift == 1 && flagval1==0){ flagval1=1; flagval2=0; } val1[shift]=Low[shift]-5*Point; } if (....signal condition is true..............) { if (shift == 1 && flagval2==0) { flagval2=1; flagval1=0; } val2[shift]=High[shift]+5*Point; } } if (flagval1==1 && CurTime() > GlobalVariableGet("AlertTime"+Symbol()+Period()) && GlobalVariableGet("SignalType"+Symbol()+Period())!=OP_BUY) { // Print("Last Alert before BUY = ",GlobalVariableGet("LastAlert"+Symbol()+Period())); // if (GlobalVariableGet("LastAlert"+Symbol()+Period()) < 0.5) // { if (SoundON) Alert(TimeToStr(CurTime(),TIME_DATE), " BUY ",Symbol() , TFToStr(Period())," ",TimeHour(CurTime()),":",TimeMinute(CurTime())); if (EmailON) SendMail("BUY signal alert","BUY signal at Ask="+DoubleToStr(Ask,4)+", Bid="+DoubleToStr(Bid,4)+", Date="+TimeToStr(CurTime(),TIME_DATE)+" "+TimeHour(CurTime())+":"+TimeMinute(CurTime())+" Symbol="+Symbol()+" Period="+Period()); // } tmp = CurTime() + (Period()-MathMod(Minute(),Period()))*60; GlobalVariableSet("AlertTime"+Symbol()+Period(),tmp); GlobalVariableSet("SignalType"+Symbol()+Period(),OP_SELL); // GlobalVariableSet("LastAlert"+Symbol()+Period(),1); } if (flagval2==1 && CurTime() > GlobalVariableGet("AlertTime"+Symbol()+Period()) && GlobalVariableGet("SignalType"+Symbol()+Period())!=OP_SELL) { // Print("Last Alert before SELL = ",GlobalVariableGet("LastAlert"+Symbol()+Period())); // if (GlobalVariableGet("LastAlert"+Symbol()+Period()) > -0.5) // { if (SoundON) Alert(TimeToStr(CurTime(),TIME_DATE), " SELL ",Symbol() , TFToStr(Period())," ",TimeHour(CurTime()),":",TimeMinute(CurTime())); if (EmailON) SendMail("SELL signal alert","SELL signal at Ask="+DoubleToStr(Ask,4)+", Bid="+DoubleToStr(Bid,4)+", Date="+TimeToStr(CurTime(),TIME_DATE)+" "+TimeHour(CurTime())+":"+TimeMinute(CurTime())+" Symbol="+Symbol()+" Period="+Period()); // } tmp = CurTime() + (Period()-MathMod(Minute(),Period()))*60; GlobalVariableSet("AlertTime"+Symbol()+Period(),tmp); GlobalVariableSet("SignalType"+Symbol()+Period(),OP_BUY); // GlobalVariableSet("LastAlert"+Symbol()+Period(),-1); }

Please there is difference between one alert per signal and Alert once per bar.
Please any help on the code snippet for indicator to alert once per signal and not once per bar
This is for alert once per bar. What of Alert once if only the signal is true?
extern int AlertCandle = 1; // extern bool ShowChartAlerts = false; // extern string AlertEmailSubject = ""; // // datetime LastAlertTime = -999999; // // string AlertTextCrossUp = "Sixths cross UP"; //---- type your desired text between the quotes // string AlertTextCrossDown = "Sixths cross DOWN"; //---- type your desired text between the quotes // // // ============================================================================================================================================ // double AlertPriceHigh, AlertPriceLow; int count = 1; int ProcessAlerts() { // //+------------------------------------------------------------------+ // if (AlertCandle >= 0 && Time[0] > LastAlertTime) { // // // === Alert processing for crossover UP (indicator line crosses ABOVE signal line) === // if (Close[AlertCandle] > AlertPriceHigh && Close[AlertCandle+1] <= AlertPriceHigh) { // string AlertText = Symbol() + "," + TFToStr(Period()) + ": " + AlertTextCrossUp; // if (ShowChartAlerts) Alert(AlertText); // if (AlertEmailSubject > "") SendMail(AlertEmailSubject,AlertText); // LastAlertTime = Time[0]; // } // if (Close[AlertCandle] > AlertPriceLow && Close[AlertCandle+1] <= AlertPriceLow) { // AlertText = Symbol() + "," + TFToStr(Period()) + ": " + AlertTextCrossUp; // if (ShowChartAlerts) Alert(AlertText); // if (AlertEmailSubject > "") SendMail(AlertEmailSubject,AlertText); // LastAlertTime = Time[0]; // } // // // === Alert processing for crossover DOWN (indicator line crosses BELOW signal line) === // if (Close[AlertCandle] < AlertPriceHigh && Close[AlertCandle+1] >= AlertPriceHigh) { // AlertText = Symbol() + "," + TFToStr(Period()) + ": " + AlertTextCrossDown; // if (ShowChartAlerts) Alert(AlertText); // if (AlertEmailSubject > "") SendMail(AlertEmailSubject,AlertText); // LastAlertTime = Time[0]; // } // if (Close[AlertCandle] < AlertPriceLow && Close[AlertCandle+1] >= AlertPriceLow) { // AlertText = Symbol() + "," + TFToStr(Period()) + ": " + AlertTextCrossDown; // if (ShowChartAlerts) Alert(AlertText); // if (AlertEmailSubject > "") SendMail(AlertEmailSubject,AlertText); // LastAlertTime = Time[0]; // } // // } // return(0); // } //
Will this work ?

I tested the above it didn't work
Solution to this problem is still at large.........
I dont see a single else if in that code.

i now know where the problem is from
Signals and the corresponding alert must be defined separately
datetime previous =0; for(int i =Bars-1; i>=0; i--){ double aa = iMA(..............................); double bb = iMA(.............................); if(aa>bb){ Val1[i] = High[i]+5*Point; to..Do here..; } if(aa<bb){ Val2[i] = Low[i]-5*Point; to..Do here..; } if(Alerts){ for(i=i+1, i>=0; i--){ double aa = iMA(..............................); double bb = iMA(.............................); }// note the position of the end of the iteration for the alert if(aa>bb){ if (previous Alert != Time[0]){ Alert(); SemdMail(); } //note the position of this also previous = Time[0]; } if(aa<bb){ if (previous Alert != Time[0]){ Alert(); SemdMail(); } //note the position of this also previous = Time[0]; }
Will this work?
Most of us don't know much about this mql4 and now there is mql5 to deal with ahead.......
