Hello, I need help in this code below, I want this expert advisor to sell if the last trade was of buy and buy if the last trade was of sale.

#include <Trade\Trade.mqh>
CTrade trade;

void OnTick()
  {
      double ask, bid, last;
      
      ask = SymbolInfoDouble(_Symbol, SYMBOL_ASK);
      bid = SymbolInfoDouble(_Symbol, SYMBOL_BID);
      last = SymbolInfoDouble(_Symbol, SYMBOL_LAST);
      
    
      if(PositionsTotal()==0)
         {
            Comment("Compra");
            trade.Buy(1, _Symbol, ask, ask-1, ask+1, "");
         }
      else if(PositionsTotal()==0)
         {
            Comment("Venda");
            trade.Sell(1, _Symbol, bid, bid+1, bid-1, ""); 
         }
   
  }
 

What is (in your understanding) a "transaction"? It:

  1. deal ENTER THE MARKET
  2. deal EXIT THE MARKET
?

yes.
 
cmagule :
yes.

What "yes"? Give an exact answer - there are TWO options in my question.

 
You are referring to a "trade", which is not exact enough for your question.

A buy trade goes as follows:
Place order, get filled with one or more buy deals.
This results in a position.

This position is closed by sell deals, eventually until it is liquidated.

Same goes for a short sell trade. Only vice versa.

So what are you referring to?

The position or the deals?

ladimir Karputov:




thank you sir, is exactly what i was looking for.

 

Good afternoon, what happened to my account <...> with an initial investment of <...>?

Because it is indicated as "NOT VALID" until 1.6.2021 it was visible!

You can answer me on my email <...> as not knowing English I can use an online translator from Google.

I am worried and do not understand what happened to the sums paid.

I look forward to your verification and a reply email.

I speak only Italian....

Thank you. <...>
