JBrainTrend1Stop_Alert - MetaTrader 5 Script - MT4/MT5 Resources
JBrainTrend1Stop trend indicator features alerts, emails and push notifications.
In order to implement alerts, email messages and push notifications, the following changes were made to the indicator code:
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 buy arrow(&B)[], // indicator buffer with uptrend signals
Double sales arrow(&S)[], // indicator buffer with downtrend signals
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 BuyStopBuffer and SellStopBuffer are the names of indicator buffers used to store up and down trend signals (stop lines for long and short positions). If there is no appropriate trend, zero value or EMPTY_VALUE should be present in the indicator 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.
