Can you tell me who has encountered and knows how to get from this line:

29301441,1475681547,0,0.01,EURUSD,1.1207,0.0000,0.0000,1475690944,1.1213,0.00,0.00,0.60,,13134545

like this:

-118,120,-39,52,-58,-76,62,-66,-49,-97,-38,-86,-125,-52,-70,-96,89,-23,13,-91,111,74,-79,16,65,127,116,-76,99,5,27,48,42,44,55,-94,84,-72,-63,115,26,18,-47,-46,5,-55,32,68,114,-20,46,-7,79,7,82,78,-91,41,82,-114,121,112,-64,-106,35,-10,24,-128,58,-81,-69,92,34,79,64,-97,52,-95,127,-18,-46,104,104,85,56,93,8,100,14,-52,-88,-38,-28,-76,-49,35,-74,27,120,74,53,124,-104,-59,-1,41,-127,-99,103,104,-38,2,47,-93,68,35,-15,44,123,47,78,-117,15,-114,-46,-98,-108,-26,

Thank you!

The second string is more than similar to a signed char array. That is, the whole "string" could just be a binary structure printed byte-by-byte, and maybe it was encrypted first, so there's no 0
 

Good afternoon.

I am not a programmer myself, but I want to make my EAs to send me email notifications of the signals. The task is simple and seems to work, but when the signal condition is fulfilled they send infinite number of emails.

Please help me to send only one email at each signal.

Here is an example of my code for the simple moving average. What should I add or fix?

int init()
  {
   return(0);
  }
start()
  {
//-----------------------------------------------------------------------------------------------------
// Сигналы
//-----------------------------------------------------------------------------------------------------
if(Open[1]>ma && Close[1]<ma)  {
bool res = SendMail("Сигнал", " Покупай");
}
if(Open[1]<ma && Close[1]>ma) {
SendMail("Сигна", "Продавай");
}
//-------------------------------------------------------------------
   return(0);
  }

Add datetime mailTime and remember the time before sending, so that you don't have to re-send the message

datetime mailTime=0;
int init()
  {
   return(0);
  }

start()
  {
//-----------------------------------------------------------------------------------------------------
// Сигналы
//-----------------------------------------------------------------------------------------------------
if(Open[1]>ma && Close[1]<ma && Time[1]>mailTime)  {
bool res = SendMail("Сигнал", " Покупай");
if (res) mailTime=Time[1];
 }
if(Open[1]<ma && Close[1]>ma && Time[1]>mailTime) {
bool res=SendMail("Сигна", "Продавай");
if (res) mailTime=Time[1];
 }
//-------------------------------------------------------------------
   return(0);
  }

ps. it's time to switch from start() to OnTick() in EAs

pps. mailTime should also be saved in global variables of the terminal in case of restart of Expert Advisor.

It did not work. It keeps sending the messages all the time.

With this year no emails are being sent at all((

So what is your ma equal to? Is it the ma on the zero bar by any chance?

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

 
ev85:

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,0);

Then everything is clear. The Mach on the zero bar is constantly recalculated - so the signals will come at every tick.

Try it this way:

static datetime TimeN=0;

int Signal=0;


int init()

  {

   return(0);

  }

start()

  {

//Операции выполняются только при появлении следующего бара

   datetime TimeC=iTime(NULL,TF,0);

   if(TimeN==0)TimeN=TimeC;

   if(TimeN==TimeC && Signal==1) return;

   TimeN=TimeC;

   Signal=0;


//-----------------------------------------------------------------------------------------------------

// Сигналы

//-----------------------------------------------------------------------------------------------------

if(Open[1]>ma && Close[1]<ma)  

{

bool res = SendMail("Сигнал", " Покупай");

Signal=1;

}

if(Open[1]<ma && Close[1]>ma) 

{

SendMail("Сигнал", "Продавай");

Signal=1;

}

   return(0);

  }


In general, usually do a comparison

ma=iMA(NULL,0,MovingPeriod,MovingShift,MODE_SMA,PRICE_CLOSE,1);

ma>Open[0];

Yes, after some action it turned out that the string is indeed a signed char. Now the question is: how to make it readable on the server?
