Waddah_Attar_Trend_Alert - MetaTrader 5 Script - MT4/MT5 Resources
Real author: Engineer. wada attar
Waddah_Attar_Trend Indicator has alert, email and push notification capabilities.
In order to implement alerts, email messages and push notifications, the following changes were made to the indicator code:
//----Alert input 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
//+------------------------------------------------------------------+
//|Buy signal function |
//+------------------------------------------------------------------+
Blank buy signal( string signal sir name, // indicator name text for emails and push messages
Double & color array[], // color index buffer
Integer color index, // Color index in the color index buffer used to generate the signal
Constant integer rate_total, // current number of bars
Constant integer BEFORE_CALCULATION, // number of bars of the previous price change
const double & close [], // closing price
const int & spread[]) // spread

where ColorIndBuffer is the name of the color index buffer used to store the line color as an index, and 0 and 1 are the number of colors in the color index buffer.
It is assumed that the only calls to the BuySignal() and SellSignal() functions will be used in the OnCalculate() block of the indicator code.
