PolarSeaman:
Still haven't figured out how to count the seconds until the bar closes on the current period. I need your help.

I gave you the function.

 
Artyom Trishkin:

Yes, but the code above, in the comment, counts down smoothly every second and the function is jerky. On M1, out of 60 bars, 3 or 4 times there is no alert.

That's because the function uses TimeCurrent() - arrival time of the last quote. You need to replace this time with a local TimeLocal() with a calculated offset (you have already been told about it).

 
Artyom Trishkin:

I don't know how to do it correctly, so I found a code that counts down time to close H1 without ticks, and I'm trying to use it, I replacedTimeCurrent() in your function, but it doesn't want to show me seconds to close.

Please advise how to implement the idea in the code:
If warrants were open and now there are none = Alert.

Something like this probably...
double x=0;
If(OrdersTotal >0) {x=1;}
If (OrdersTotal <x) {Alert ;}
x=0;

 
Tigerfreerun:
Please tell me how to implement the idea in the code:
If warrants have opened and now there are no warrants = Alert.

Something in this style probably...
double x=0;
If (OrdersTotal >0) {x=1;}
If (OrdersTotal <x) {Alert ;}
x=0;

If(OrdersTotal ==0) {Alert ;}
 
Alekseu Fedotov:
If (OrdersTotal ==0) {Alert ;}
Then the signal is cyclic. And even if no orders were opened. The idea is that 1) Orders are open 2) now there are no orders 3)1 Alert
 

Guys!

There are a lot of objects on the graph.

But when you access it.

Comment(ObjectsTotal());

It says there's only three.

Why isn't it counting arrows?

Do it like this. The code is almost correct. Only one word is missing there:

static double x=0;
If (OrdersTotal >0) {x=1;} 
If (OrdersTotal <x) {Алерт ; x= 0;}

Maybe because they are Wingdings font symbols
