Thank you! It's working like clockwork. ))
in this line
if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) { Print("break "+GetLastError()); break;}
The order is breaking but the error code is 0. - Why does this happen?
because you have a check for the condition that the order selected using the OrderSelect() function is not a market order, print to the log and break
the opposite should be done: if the order is market and the order has a magic number and a symbol and . then close it and do not interrupt the iterations of the orders

Hi all! Is there a script or indicator for the following task? I need a horizontal line to be drawn in the terminal and follow the price at a certain distance (like trailing, but only graphically). How much will this script increase MT's load? Thank you in advance!

i.e. this line
if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) { Print("break "+GetLastError()); break;}
change it to
if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==true) { here we are going to close everything }
but the meaning is the same.
I don't really understand why OrderSelect can return false and yet GetLastError() = 0.
advise on the function to close all orders
I would go through the orders in reverse order. for(int i=total-1;i>-1;i--)
Please help me find an error, I can't get it right and then read it out of the file
here is the code:
int handle;
double value,Price,PriceLast,asd;
handle=FileOpen("EURUSD5up.dat",FILE_BIN | FILE_READ | FILE_WRITE);
if(handle<1)
{
Print("can't open file error-",GetLastError());
return(0);
}
asd = (Price - PriceLast);
FileWriteDouble(handle, asd, DOUBLE_VALUE);
FileSeek(handle, 0, SEEK_SET;)
value=FileReadDouble(handle,DOUBLE_VALUE);
Print(value);
FileClose(handle);
here is the result: 2011.02.08 10:18:27 2010.12.31 18:47 TEST EURUSD,M5: 0
I would go through the orders in reverse order. for(int i=total-1;i>-1;i--)
thank you!, it is strange that this variant is not presented in the sample help
стандартный кодебазовский RSI, являющийся отношением средней положительных изменений к средней отрицательных, не то же самое
that the real, original RSI, which is the ratio of the sum of positive changes to the sum of negative changes.
Although I have known and understood it for years, unlike the codebase one, I will not say that my version is correct.
These are the basics, I think everyone who has been on the market for a long time knows that rsi is sumpos/sumneg*100
by the way, they also twisted MacDi - they made the main machinewheel EMA

Thank you very much for your reply. Unfortunately I'm not very good at programming. Could you show me how it should look like, for example for a line lagging the price by 3p upwards with the line colour blue.
