Hello! Would one of the esteemed gurus like to check the start of my first EA? Is it possible to move on? Maybe i missed something? I would be very grateful for any specifics. I've seen somewhere on the forum how to make only one position open, but I didn't copy it and now I can't find it. Help, please.
Thank you!

Additionally, BAY (as well as Sell) positions can be opened under different conditions, and depending on the conditions under which the position was opened (e.g. BAY), there will be different closing conditions. (e.g. BAY), there will be different closing conditions.
How do I translate this in MKL?

We select the order in the loop. If it is a Buy and all other data (symbol, magician, whatever) meets the criterion of having to close it at "proper closing conditions", then we close it if there are "proper closing conditions".
It's a bit vague to me, but after a bit of digging I think I'll understand. Thank you very much for not turning away or lecturing from the peaks of knowledge, like some comrades from the Soviet country.
I figured out how to close it this way:
//-------Example(mine) of an order to open a position with a binding close (by ticket)-----------------------------------------------------
//Local variable that opens a BAY order (instead of line 63)
int Ticket_1() = (OrderSend(Symbol(),OP_BUY,Lots,Ask,0,Bid-1500*Point,Bid+1500*Point))
//-------Then the closure for this particular order could be as follows:-----------------------------------------------------
if (Ticket_1()==true) //if order #1 was opened, then...
{ if (Yellow_0>Red_0 && (Yellow_0-Red_0)<(Yellow_1-Red_1)) //Yellow is higher than red, contraction(condition)
{ if (MA_2 < MA_1 && MA_1 > MA_0);} //Red above the middle one(condition)
else (Yellow_0>Red_0 && (Yellow_0-Red_0)>(Yellow_1-Red_1)) //Yellow above red, expansion(condition)
{ if (MB_2 < MB_1 && MB_1 > MB_0);} //Upper Bollinger break (condition)
bool Ans=OrderClose(Ticket,Lot,Bid,0); //...close order (lockvariable)
Alert("Attempting to close the order with Bid("Lots"),price("Ask"). Waiting for reply...");
if (Ans==true) // It worked :)
{
Alert ("Close BAY order by lot("Lots"),Closing price("Bid");
break; // Exit from the position closing loop
}
}
Please give an analysis, well on the previous post too. Sorry for being stubborn, but you see - you're the only one who replies... Thank you!

Well, it's a bit hazy, isn't it?
1. you have to determine the fact of occurrence of the condition to close the order
2. In the cycle, you review all the open positions and, when you find the required Buy order, you close it.
This is an example of a cycle:
I.e., to close the Buy order at the current symbol (on the chart where the Expert Advisor is running) and with a magic number of 100500 (for example), you should call the function like this
You don't have to write the number 100500, usually the magic number is already set in the EA to a variable, for example int Magic = 100500; Then you need to write Magic instead of 100500
I did not write anything in the loop where the selected position should be closed, as it should call the function to close the order according to the ticket. This is usually a call of a full function with return codes of the trade server handled. You can write there a simple command to close the selected order OrderClose() to check;
It's much easier to read that way. Sorry.
It's also possible to edit an old post, so as not to create duplicates ;)

It's a bit foggy.

Thank you. But as I understand it, the magik is assigned automatically when the order is opened. That is why I cannot determine the conditions under which the order was opened, and therefore I do not know the conditions under which it should be closed.
