ColorParabolic_Alert - MetaTrader 5 Script - MT4/MT5 Resource
This color parabolic semaphore signal indicator has alert, send email and push notification functionality.
In order to implement alerts, email messages and push notifications, the following changes were made to the indicator code:
New input parameters introduced
Input unit number = 1 ; //The number of bars of the signal Input boolean sound on = true ; //enable alert Input unit alarm number = 2 ; //Alarm number input boolean email-on = false ; //enable mailing signal input boolean pressed = false ; //enable signaling to mobile devices
Three new functions have been added at the end of the indicator code: BuySignal(), SellSignal() and GetStringTimeframe()
//+------------------------------------------------------------------+ //|Buy signal function | //+------------------------------------------------------------------+ Blank buy signal( string signal sir name, // Indicator name text for emails and push messages double buy arrow(&B)[], // Indicator buffer with buy signal constant integer rate_total, // Current number of bars constant integer ex_calculation, // Number of bars for the previous price move constant double & close [], // Closing price constant integer & spread[]) // spread { //--- stationary unit counter = 0 ; if (Rates_total!=Prev_calculated) counter = 0 ; boolean buysignal = false ; booleanSeriesTest = array getSeries (BuyArrow); integer exponent; if (series test) index = integer (number of items); Other indexes=Rates_total- integer (number of items) -1 ; if ( Normalized Double (BuyArrow[index], _number ) && BuyArrow[index]!= null_VALUE ) BuySignal= True ; if (BuySignal && counter<=NumberofAlerts) { counter++; MqlDateTimeTM ; BuildTime ( timecurrent (),tm); string literal = string time ( timecurrent (), TIME_DATE ) + "" + string (tm.hour) + ":" + string (tm.minute); SeriesTest = arrayGetSeries ( close ); if (series test) index = integer (number of items); Other indexes=Rates_total- integer (number of items) -1 ; double question = close [index]; double bid = close [index]; SeriesTest = arrayGetSeries (spread); if (series test) index = integer (number of items); Other indexes=Rates_total- integer (number of items) -1 ; bid +=spread[index]* _views ; Thin string question = double to string ( question , _number ); stringbid = double to string ( bid , _number ); String sPeriod=GetStringTimeframe( ChartPeriod ()); if (sound on) alert ( "buy signal\n ask=" , ask , "\n bid=" , bid , "\n current time=" , text, "\n symbol=" , symbol (), "period=" ,s period); if (email) send mail (signal sir name + ": buy signal alert" , "buy signal at inquiry =" + ask + ", bid =" + bid + ", date = " + text + " symbol = " + symbol () + " period = " + s period); if (push away)="functions">Send Notification(Mr.SignalName+ ": Buy Signal at Ask=" +Ask+ ", Bid=" +Bid+ ",Date=" +Text+ "Symbol=" + Symbol ()+ "Period=" +sPeriod); } //--- } //+--------------------------------------------------------------------------------+ // | Sell Signal Function | //+----------------------------------------------------------------+ Blank Sell Signal( String SignalMr.Name, // Indicator name text for emails and push messages Double sales arrows (&S)[], // indicator buffer with sell signals constant integer rates_total, // current number of bars constant integer prev_calculated, // number of bars of the previous price movement constant double & close [], // closing price constant integer &spread[]) // spread { //--- stationary unit counter = 0 ; if (Rates_total!=Prev_calculated) counter = 0 ; boolean SellSignal = False ; boolean Series Test = Array Get Series (Sell Arrow); integer index; if (SeriesTest) index = integer (number of bars); else index = Rates_total - integer (number of bars) - 1 ; if ( normalized double (SellArrow[index], _Number ) && SellArrow[index]!= null_VALUE ) sell signal = true ; if (SellSignal && Counter<=NumberofAlerts) { Counter++; MqlDateTimeTM ; BuildTime ( timecurrent (),tm); string literal = string time ( timecurrent (), TIME_DATE ) + "" + string (tm.hour) + ":" + string (tm.minute); Series test = array to get series ( closed ); if (series test) index = integer (number of items); other indexes = Rates_total - integer (number of items) - 1 ; double ask = close [index]; double bid = close [index]; series test = array to get series (propagation); if (series test) index = integer (number of items); other indexes = Rates_total - integer (number of items) - 1 ; bid + = spread [index]* _view ; string ask = Double to String ( ask , _number ); string bid = Double to String ( bid , _number ); string sPeriod = GetStringTimeframe( ChartPeriod ()); if (sound on) alert ( "sell signal\n ask=" , ask , "\n bid =" ,bid, "\ n current time=" , text, "\n symbol=" , symbol (), "period=" ,s period); if (email) send mail (signal sir name +> ": sell signal alert", "sell signal on ask=" + ask + ", bid = " + bid + ", date = " + text + " symbol = " + symbol () + " period = " + s period); if ( push) send notification ( signal sir name + ": sell signal on ask= " + ask + ", bid = " + bid + ", date = " + text + " symbol = " + symbol ( ) + " period = " + s period); ;
Added several calls to the BuySignal() and SellSignal() functions after the indicator calculation period in the OnCalculate() block
//--- buy signal( "colorparabola_alert" ,BuyBuffer,rates_total,prev_calculated,close,spread); sell signal( "colorparabola_alert" ,SellBuffer,rates_total,prev_calculated,close,spread); //---
Where BuyBuffer and SellBuffer are the names of the indicator buffers used to store buy and sell signals. Due to empty values in the indicator buffer must be set to zero or EMPTY_VALUE.
It is assumed that the only calls to the BuySignal() and SellSignal() functions will be used in the OnCalculate() block of the indicator code.
