posted a screenshot of one from their website with forecasts based on levels, might be of interest https://c.mql4.com/forum/2011/03/gfsnlbx.GIF

take the name of the website from the picture, it's not that simple... http://www.gelium.net/
 

Хе-е-е-е-е-е-е-е-е-е-е-еелп!!!!! :o( Colleagues, have a few questions on MQL:

(1) Problem with orders.

A buy order opens on some condition:

ticket=OrderSend(Symbol(), OP_BUY, 0.1, Ask, 3, 0, 0, "", Green);

and a sell order:

ticket=OrderSend(Symbol(), OP_SELL, 0.1, Bid, 3, 0, 0, "", Green);

An order, or one or the other does open, - appears in the tester and a ticket value is assigned to something. No error is returned. Here is the close order:

   if(OrdersTotal()>0 && "условие закрытия")
   {
      Print("Ордер вообще то есть");
      if(OrderSelect(ticket, SELECT_BY_TICKET)==true)
      {
         Print("Ну и где этот ордер, раз ... туды его в ...");
         CurrentTypeOrder=OrderType();

         if(CurrentTypeOrder==0)
         {
            OrderClose(OrderTicket()  , 0.1, Bid, 3, Red);
         }

         if(CurrentTypeOrder==1)
         {
            OrderClose(OrderTicket()  , 0.1, Ask, 3, Red);
         }
      }
      else
      {
         Print("OrderSelect() вернул ошибку - ",GetLastError());
      }
   }

The close condition works fine, and the first Print is displayed. But OrderSelect cannot find any order, despite the fact that it definitely exists and all the testing still holds this first open order. I can't understand where I made a mistake.

I will try to repeat the previous question - how (I need an idea) to implement in an EA a time series (some kind of transformation) similar to the properties of an indicator. Well ... sort of, so that the entire astrolabe is not recalculated with the arrival of a new tick? Perhaps my amateurism in MQL does not allow me to formulate it correctly.

Not quite sure what you're talking about. Can you write what you want to get (in detail in order (point by point))?
 

Farnsworth:

I can't figure out where I went wrong.

You have to change the ticket, you probably don't change it everywhere when you open it.

It doesn't matter what kind of transformation, let it be MA(n) for specifics. If I do this transformation using an indicator, then (as I understand) when a new tick/bar comes, the entire series will not be recalculated. Is it possible to obtain the same effect in an Expert Advisor without using indicators?
 
TheXpert:

I used all sorts of examples from documentation and simple MT delivery examples for inspiration. I seem to have done everything by analogy, if it doesn't take a lot of energy - could you share the sacred secret, or a link to read. What is "changing the ticket"? My understanding was that it is a variable that is reassigned (I should have one order at one point in time or none at all).
 
I'm sorry to pry, but you'd be better off formulating the ToR for a conditional example than wasting time wrestling with mql. They will write it for you without any problems.

A more specific question: the values of the conventional indicator at each moment of time are required for all candlesticks on the chart or for a certain number of the latest ones?

I'm sorry for giving advice, but you had better formulate TOR for a hypothetical example rather than wasting time wrestling with mql. That's who they will write it to without any problems.

You still need some understanding of MQL, and besides, it's not that bad :o)
