Questions from Beginners MQL4 MT4 MetaTrader 4 - page 226

Alexey, thank you for your answers and your help.

New question, is it possible to duplicate chart tabs in MT4? That is, not a template to set the chart parameters each time, but a full copy of the tab with the selected currency, timeframe and chart parameters. Is there such a thing or not?

Fighting, searching, finding and re-hiding!


ElenkaVladi:

New question.

Yeah, you're welcome.

The easiest one is the pattern. Why don't you like it? You have set the timeframe, scale, background colour, colour of candlesticks, you have set the required indicators and saved it as default.tpl. Now when you open a new chart, everything is ready for you.

No, the question seems to be different. When a user opens a chart and installs an indicator, he knows neither TF nor symbol. The script should select the symbol and the TF. (And the indicator may be loaded at the same time, or a template may be selected).

Ah, that's how it works, no thought of default.tpl. :))

@makssub in PM asking for MQL4 code, then this code

#property strict
//+------------------------------------------------------------------+
void OnStart()
{
   while(!IsStopped())
   {
      int ticket = -1;
      string ord_sym = "";
      int max_pips = INT_MIN;
      for(int i = OrdersTotal() - 1; i >= 0; i--)
      {
         if(!OrderSelect(i, SELECT_BY_POS, MODE_TRADES) || OrderType() > OP_SELL) continue;
         string _sym      = OrderSymbol();
         double sym_point = SymbolInfoDouble(_sym, SYMBOL_POINT);
         double sym_price = OrderType() == OP_BUY ? SymbolInfoDouble(_sym, SYMBOL_BID) : SymbolInfoDouble(_sym, SYMBOL_ASK);
         int ord_pips     = fabs(PriceToInteger(OrderOpenPrice(), sym_point) - PriceToInteger(sym_price, sym_point));
         if(max_pips < ord_pips)
         {
            max_pips = ord_pips;
            ticket = OrderTicket();
            ord_sym = _sym;
         }
      }
      if(ticket < 0) Comment("");
      else Comment("Max pips in order = ", max_pips, " , Symbol = ", ord_sym, " , ticket = ", ticket);
      Sleep(123);
      RefreshRates();
   }
   Comment("");
}

Alexey Viktorov:

Well, in simple words, it goes like this:

We create a variable of datetime type and record the time of the current D1 candle in it when we close the order with a profit. And before opening another order, we check the value of this variable with the time of the current D1 candle. Accordingly, if the current time is higher, we can open. Otherwise, we smoke smoke smoke.

Can you show me an example, I just don't have enough experience to implement what you said?
 
Hi all! Please advise a MQL4 tutorial, up to date.
 
Nikolay Grigoryev:
Hi all! Please advise me a MQL4 tutorial relevant to today.

there is only one textbook, the old Kovalev textbook. It was up to 2016 or so. Then a lot of things from 5 were transferred to 4. Thank God the order system was retained. There are no more textbooks (I didn't find any, and others didn't either). Only articles here and internet searches.

I have written a simple indicator. When crossing zero, it doesn't draw the line, even though the buffers have values. Can you please tell me where I went wrong.
