Do you know the answer to my additional question?

The condition below is fine, but I don't use the update function, so I can't tell you.

P.S. I'm also a beginner.

but does anyone know if this order of listing conditions through several (&&) in one line of if() operator is acceptable?

Acceptable, although I would put more brackets - operations have different priorities in different languages - so as not to think about trivialities - something like:

if ((Max_price_1>EMA20_Open) && (Min_price_1>EMA20_Open) && (Heiniken_Red>Heiniken_Blue))
   {
    Opn_B=true;
   }

You look for highs among the x nearest neighbours of the indicator and compare them.

What does the function of searching for the last 2 maxima on RSI look like ?

Can someone show me the code?

...(does refresh with RefreshRates() have to be done?)...

What is the purpose of RefreshRates? The point is, that after a new tick comes, built-in variables (like Ask, Bid, etc.) are read and passed to start() function. If the start takes too long, a new tick may come, but variables are not updated. That is when you call RefreshRates.

When start takes too long? Usually when a trade operation is in progress - there is a network exchange, the server's permission for the operation is required, and a response is expected. So usually RefreshRates is used when more than 1 order is opened/closed on one tick. It is used between operations.

Strange as it may seem, the task is not easy. Technically you have to go back and look for points such that:

y(x-1)<y(x) and y(x)>y(x+1).

But this will find local extrema, and that's a bit of a stretch - you won't be happy with the result.

I'm thinking roughly the same, but confused by some thoughts: how will the 1st maximum be distinguished from the 2nd,

because this condition fits both the first maximum and the second and third maximum....

I can recommend you to search and read about ZigZag (there is plenty of literature). I would recommend the Rochev zigzag - 'Zigzag R'.

Had a look at....((( I don't understand anything clearly... The array is filled in, then the shifft function is unclear what exactly it does.

That's the thing - the matter is quite complex - but this zigzag works without error. You can use it for RSI.

can someone show it in code form ?

It looks like this:

bool exit_for=false;
int max_1=0;int max_2=0;
for(int k=0; k<Bars; k++)
{
	if(	iRSI(Symbol(),0, rsi_period,PRICE_CLOSE, k)<iRSI(Symbol(),0, rsi_period,PRICE_CLOSE, k+1)
		&& iRSI(Symbol(),0, rsi_period,PRICE_CLOSE, k+1)>iRSI(Symbol(),0, rsi_period,PRICE_CLOSE, k+2) 	)
	{
		//Если это первый максимум:
		if( max_1==0)
			max_1= k+1;//Записываем номер бара экстремума
		else
		//Если первый найден, записываем второй
		{	
                        max_2= k+1;
                        exit_for=true;
                } 
	}
        //Выход из цикла, когда найдены оба максимума
        if( exit_for==true) k=Bars+1;  
}
