Rustam Bikbulatov:
Who else can help?)

You seem to have been given comprehensive answers and examples, but you still need to read the help to understand how functions are called and why the static modifier is used.

Here's another way, maybe it'll be easier for you to understand:

int N(bool reset=false) // если вызываем N() то возвращает следующее значение n++, при первом вызове n=0, но вернет 1, т.к. n=0, а затем n++, если нужно 0 то 
			// или  static int n=-1; или вызывайте сначала N(true)
  {                     // если вызываем N(true), то сбрасываем n=0 и возвращзаем 0
   static int n=0;
   if(reset) n=0; else n++;
   return n;
  }

Igor Makanu:

You seem to have been given comprehensive answers and examples, but you still need to read the help to understand how functions are called and why the static modifier is used.

Here's another variant, maybe this will make it easier for you to understand:

The first example shows one function call when no position is taken and the returned result is compared.

if( ((OpenB-Ask)/ma+TimeB/60) > N() )

That's why it might be a good idea to do a simple return without zeroing and adding. Which I have implemented in 2 variants

Hi, how do I make when I manually drag and drop a buystop pending order, the other sellstop pending order will move with it?

How can I bind one to the other, so that when I move one, it will move both of them at once?

Здравствуйте. У меня алгоритм такой

if (CountBuy() == 0)
{

BuySignal = h1; tttp=1; 
if (BuySignal > 0 && tttp==1 && h2>0)
{
CloseSell();
ticket = OrderSend(Symbol(), OP_BUY, Lots, Ask, Slippage, 0, 0, comment, Magic, 0, Blue);

if (ticket > 0)
{

if (OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))
{

SL = NormalizeDouble(Ask-StopLoss*Point, Digits);

TP = NormalizeDouble(Ask+TakeProfit*Point, Digits);

res = OrderModify(OrderTicket(), OrderOpenPrice(), SL, TP, 0);
if (!res)

Print("Ошибка модификации ордера на покупку, ASK=" + DoubleToStr(Ask) + ", SL=" + DoubleToStr(SL) + ", TP=" + DoubleToStr(TP)); 
}
}
}
}
if (CountSell() == 0)
{
SellSignal= l1; tttp=-1;
if (SellSignal > 0 && tttp==-1 && l2>0)
{
CloseBuy();
ticket = OrderSend(Symbol(), OP_SELL, Lots, Bid, Slippage, 0, 0, comment, Magic, 0, Red);
if (ticket > 0)
{
if (OrderSelect(ticket, SELECT_BY_TICKET, MODE_TRADES))
{
SL = NormalizeDouble(Bid+StopLoss*Point, Digits);
TP = NormalizeDouble(Bid-TakeProfit*Point, Digits);
res = OrderModify(OrderTicket(), OrderOpenPrice(), SL, TP, 0);
if (!res)

Пытаюсь сделать, чтоб условия на открытие ордера проверялось бы через какое-то кол-во баров, а так сразу открывается другой ордер

Write your own ticks and put them in the strategy tester.

Greetings. Can you tell me what the problem is and how to solve it?

I have changed some candlesticks in history for testing, for the 1st, 2nd, 3rd and 6th.

When testing, the second one is processed, the third one is drawn (without processing), and stops giving an error stopped because of Stop Out
