Why Does MQL5 Behave Unexpectedly
you have not shown code that defines Cross_Correlo so how do you expect a response?
I recommend that you use the search field at top of this page. There are many articles and forum threads discussing multi symbol trading.
EDIT: could it be because you replaced _Symbol with Cross_Correlo, but still have _Symbol in the MarketInfo?

I have a script in MQL5 derived from MQL4 with the appropriate libraries to make it 'work' on MQL5. It does work... but only when it feels like it. Here is the piece of code in MQL5 derived from MQL4.
If in MQL5 I launch Apri_Primario where I have _Symbol in OrderSend like OrderSend(_Symbol, OP_BUY, lott, MarketInfo(_Symbol, MODE_ASK), slipp, STp, TKp, IntegerToString(Magik) + Commento + IntegerToString(Enteglement), Magik, 0, clrGreen); , it works fine. However, if I replace _Symbol with the string containing the cross I need, Cross_Correlato , it doesn’t work. I have a few questions: 1. Is it possible to make it work by forcing it in some way?You are requesting _Symbol in Market Info but are trading Correlatio
Correlatio means correlation probably so make sure your data points for the calculation of correlation are synced across pairsyou have not shown code that defines Cross_Correlo so how do you expect a response?

input string Cross_Correlato="NZDUSD"; // CROSS CORRELATO
You are requesting _Symbol in Market Info but are trading Correlatio
Correlatio means correlation probably so make sure your data points for the calculation of correlation are synced across pairsthanks yes i fix it
string _Apri_Correlato(string oPen,double lott, int slipp,double STp,double TKp,string Commento){ int Result=0; Print("RISULTATO "+Cross_Correlato+oPen); if (oPen=="BUY"){ Print (Cross_Correlato+"_"+OP_SELL+"_"+lott+"_"+Cross_Correlato+"_"+ MODE_ASK+"_"+slipp+"_"+STp+"_"+TKp+"_"+IntegerToString(Magik)+"_"+Commento+"_"+IntegerToString(Enteglement)+"_"+Magik+"_"+0+"_"+clrGreen); Result = OrderSend(Cross_Correlato,OP_BUY,lott,MarketInfo(Cross_Correlato, MODE_ASK),slipp,STp,TKp,IntegerToString(Magik)+Commento+IntegerToString(Enteglement),Magik,0,clrGreen); if ( Result ==-1){ Print("op_BUY "+Commento+"_Result_"+Result ,GetLastError()); } }else if (oPen=="SELL"){ Print (Cross_Correlato+"_"+OP_SELL+"_"+lott+"_"+Cross_Correlato+"_"+ MODE_ASK+"_"+slipp+"_"+STp+"_"+TKp+"_"+IntegerToString(Magik)+"_"+Commento+"_"+IntegerToString(Enteglement)+"_"+Magik+"_"+0+"_"+clrGreen); Result = OrderSend(Cross_Correlato,OP_SELL,lott,MarketInfo(Cross_Correlato, MODE_BID),slipp,STp,TKp,IntegerToString(Magik)+Commento+IntegerToString(Enteglement),Magik,0,clrGreen); Print("RISULTATO "+Result+"_"+Cross_Correlato); if ( Result ==-1){ Print("op_SELL "+Commento ,GetLastError()); } } return IntegerToString( Result); }but return the same effect , i notice the info debug
Print("RISULTATO "+Cross_Correlato+oPen);write correctly 2024.10.28 09:34:52.572 SPREAD_ROBOT (AUDJPY,H1) RISULTATO NZDUSDBUY and this
Print (Cross_Correlato+"_"+OP_SELL+"_"+lott+"_"+Cross_Correlato+"_"+ MODE_ASK+"_"+slipp+"_"+STp+"_"+TKp+"_"+IntegerToString(Magik)+"_"+Commento+"_"+IntegerToString(Enteglement)+"_"+Magik+"_"+0+"_"+clrGreen);
return 2024.10.28 09:34:52.572 SPREAD_ROBOT (AUDJPY,H1) NZDUSD_1_1.0_NZDUSD_10_2_0.0_0.0_123456__SPREAD_0003__4_123456_0_clrGreen
therefore i pass correctly info to ordersend , the question is _Symbol return a string ? because NZDUSD that i passed is a string i declare in top of my code " input string Cross_Correlato="NZDUSD"; // CROSS CORRELATO "
without seeing your calculations of the functions inputs. we can only make assumptions. These may be correct, but might not be. We can only guess that your calculations are wrong for either or both the price and/or the trading lot. Maybe you are not switching to the other trading symbols. How do you expect anyone to give you answers if you only provide the last bit of code above?
EDIT: I noted this...
if (oPen=="BUY"){ Print (Cross_Correlato+"_"+OP_SELL+"_"+lott+"_"+Cross_Correlato+"_"+ MODE_ASK+"_"+slipp+"_"+ST
if it is a buy. then shouldnt the print msg say OP_BUY and MarketInfo(Cross_Correlato,MODE_ASK) ??? replace the MODE_ASK with the MarketInfo func.

i change my function and i use a mql5 syntax

now return me this error, some test ago return also

How many follow-ups, I finally found the Arcano. Basically, if you are on one chart and want to open another cross, if you haven't opened any trades on that cross before, it won't let you open it. If you open a trade manually once and then use an expert advisor, it works. However, I don't understand if this limitation is intrinsic to MetaTrader 5 or if my script is causing it unintentionally. I tend to lean towards the first option, especially since in MetaTrader 4 it has always allowed trades to be opened even if the cross had never been worked on before. Do you happen to have any insights? Thanks.
