I.e. as I understand it, when receiving data after this print and the message in the logbook 

Wait Data for GBPUSD

the test proceeds according to the algorithm?

In which function is the line? If it's in OnInit() - then after this line, everything below it won't work... OnCalculate() starts working. We are testing with not fully initialized GBPUSD indicator.
 
Hi all, I put the#property strictdirective and 4 errors popped up.
mistakes in 2,3,5,8 lines

if (CloseFriday == TRUE && DayOfWeek() == 5 && TimeCurrent() >= StrToTime(CloseFridayHour + ":00")) return (0);
op = NormalizeDouble(Bid,Digits);
tp = NormalizeDouble(Bid - (TakeProfit)*Point,Digits);
if (TakeProfit==0) tp=0;
sl = NormalizeDouble(Bid + (StopLoss)*Point,Digits);
if (StopLoss==0) sl=0;
CalcLot();
Ticket=OrderExists(OP_SELL);
if (Ticket<MaxTrades && OrderSymbol()==Symbol())
if (Ticket==-1)

Understood. Thank you. This hasn't happened before...

OnCalculate() is starting to work.

Good afternoon dear forum users.

Please tell me the reason why the cycle does not repeat.

This is my first test creation, so-so do not judge severely).

Thanks in advance.

Good evening. Put the variable kolpos in the body of start().

Thank you for your prompt reply. Very helpful.
 

Hello, everyone!

Here is the situation.

The Expert Advisor works on TF M15.

At the same time I can not copy price data for older TFs ( for example CopyHigh(Symbol,PERIOD_D1,0,period,Hi_array) )

cannot copy more than a year. In general it's not surprising, because the synchronization results show about 25 thousands 15M bars, which is exactly a year.

How can I get data for a longer period? Should I synchronize it to D1 or do I have another way?

Metatrader4 745build, how to insert a script for a previous version, scripts do not work

Please specify what exactly you want to do?

  • insert the scriptcode into an indicator or Expert Advisor
  • compile the script code
Describe what errors occur (when compiling, look at the "Errors" tab, when launching in the terminal, look at the "Experts" tab).
