How to organise a tic for an expert - and how to simulate ticks and start a timer - MQL4 and MetaTrader 4

alexey1979621, why don't you first try to write an EA on one pair without errors, and then multi-currency ones?

Trying to organise a tic for an expert - no luck. The weekend took me by surprise. How to organise it properly? For example, we have the following elementary Expert Advisor:

int delay = 180;
datetime read_now;
int init(){
   read_now = TimeCurrent() + delay;
}
int start(){
   int how_many_remains = read_now - TimeCurrent();
   Comment(StringConcatenate(
      StringSubstr("-", (how_many_remains%60 >= 0), 0),
      StringSubstr("0", (MathAbs(how_many_remains/60) > 9), 0),
      MathAbs(how_many_remains/60),
      ":",
      StringSubstr("0", (MathAbs(how_many_remains%60) > 9), 0),
      MathAbs(how_many_remains%60)
   ));
   return(0);
}

- how to simulate ticks and start a timer?

I understand that it's weekend, but in the market the schedule of holidays doesn't coincide with those in RF, and there's work to be done...

Why suffer for something you don't have to?

there will be an official release of the new builds around january 20th and.

There is a timer implemented, with what frequency you need with that and will be called.

It is better to spend your energy on studying the 5, so as not to have thousands of stupid questions.

This is for indication until the next data parsing. At 03:00 the parsing is started from the EA itself by a third-party script, at 00:00 the data is displayed on the chart, and everything is started again with the configured data update rate in seconds. Would a countdown display like this be easier to implement on a five?

Hello again!
Happy New Year, everyone!

Another rumour for help.
The "H" indicator is not showing any lines.

I can't figure out what this is about.

The code for the "H" indicator is shown above.

I have already implemented the parsing itself, why. I am interested in how to emulate tick to make this timer work. I need time to retrain to mql5 which I will lose and time is money.

Extreme values are coming out something as a result of the calculation...

The important thing is that they are displayed. :)

R_adx_time    = _N_ * (R_time + R_adx) / 500; 
R_rsi_time    = _N_ * (R_time + RSI) / 50 0;
R_rrsi_time   = _M_ * (R_time + RSI) / 50 0;

Do this and the limit values evaporate, but the problem remains.
