Solved the problem with drawing a large number of objects. Set the check on the new bar. The code turned out like this:
The only thing is that in object properties the serial number of the arrow goes not 1 2 3 ... and so on, but 1 850427 1083295 ..... I take it the counter doesn't work correctly?
My question is, how to check for a new bar on H4. In other words, the robot should look for the patterns on H4, while the chart may be on any TF?
You do not need to look for a new bar and check it.
It is enough to attach bar opening time to the arrow name. And then check the arrow with this name - if it does not exist yet, create it, if it already exists, nothing needs to be done. The name should be checked directly in the arrow creation function.

Do you need an Expert Advisor or an indicator?
An indicator would be better...
I mean that the new bar may be checked forcedly on H4, not on the current timeframe.
You don't need to look for a new bar and check.
All you have to do is add the opening time of the bar to the name of the arrow. And then check the arrow with this name - if it doesn't exist yet, create it, if it already does, you don't need to do anything. The name should be checked directly in the arrow creation function.
Wouldn't it be more costly to search through all the objects for a name?
In any case, the master code would be interesting to see.

This is, as I understand it, a template for the EA. With the name, Artyom said it right.

Yes a lot depends on the EA, if it only trades on the opening of a candle, then the decision is correct with checking a new candle.
But what is the point(advantage) of checking all objects for current time - I don't know ... but it is interesting to see this approach too.

There is no need to search for any objects. For this there is function ObjectFind
There is no need to search for any object. There is a function ObjectFind for that
From the description"It searches for an object with the specified name. There are two variants of the function:" it can only search by brute force...

Go ahead.
I knew about this operator, and I understood that it can only find the right variant by brute force.
Perhaps it is not so long - I do not know exactly - I did not do experiments - I hoped that you have great knowledge to tell me whether it is so or not, but you have led the conversation in a completely different direction ...

Where is the other direction?
