What to do with when making an EEA error? - Expert Advisors and Automated Trading

Artyom Trishkin 2016.04.12 17:58 #5581

akarustam:

Here are the wonders of testing an EA program in MT5 (see picture-file)...Can there be positive eqivity with a negative balance ? and when is the balance negative ? Before turning to Trading Nation changed my mind a lot and never got around to it yet... I think it's time to get some sleep)

If anyone interested in the open code and set let me know ? - I will certainly post it. I have started to master MT5 with hedging and now, - miracles, though)

No miracles. I have an open position with large surplus and a closed position with a loss exceeding my balance. I am not losing because I have enough funds to maintain an open position.

Artyom Trishkin:
There are no miracles. There are open positions with a large surplus, and there is a closed position with a loss greater than the size of the balance sheet. There's no downside because there are enough funds to maintain the open positions.

It's that simple... THANK YOU !

Can you please tell me what my mistake is.

for(int i=0;i<N_Sell;i++) printf("OpenSellTime[%d] = %G",i,TimeToString(OpenSellTime[i],TIME_DATE|TIME_MINUTES)," PriceOpenSell[%d] = %G",i,PriceOpenSell[i]);

The date from OpenSellTime array is not printed and not the second part of the expression - PriceOpenSell.

And, I can't find aboutprintf commandslike%G and%d.

Good afternoon All!)

This is a question for a dummy in programming...

I am trying to compile an EA for a new build. The compiler gives me lots of different errors...

Here is one of them

if(oppositedelete){delete( OP_SELLSTOP);delete( OP_SELLLIMIT);}

There are 2 errors marked in red in this code fragment:'(' - object pointer expected

Having read a bit about the subject of the error, I understood that the name is reserved and I must replace it...

So the question is what to replace it with?

To whatever you can think of. For example _delete or delete_1294_765_1912 or just Napoleon

There is this line in the code

Print (";OpenSellTime - ",TimeToString(OpenSellTime[N_Sell],TIME_DATE|TIME_MINUTES), ";PriceOpenSell", PriceOpenSell[N_Sell]);

Why do I get this text in the output:

OpenSellTime - 2015.12.01 11:15

where ";" and the second part is"PriceOpenSell"?

removed ";" - worked.

The question about printf remains...

How do I correctly send a request to close a counter position?

If I close as before, opposite one, it gets lacquered ))

Already tried everything, still gives error 2016.04.15 13:17:24 Core 1 2016.03.29 09:00:00 failed close position #64 buy 0.81 EURUSD by position #0 [Invalid request]

Which fields to fill and which ones not? I guess it doesn't matter if the position opened is short or long.

Hello, Question about the tester.

I am testing a multicurrency Expert Advisor and I would like to see in the visualizer all the windows on all currency pairs that are being traded.

In the visualizer help it is said about some command "Chart" in the "View" section of the visualizer main menu, which seems to be used to open new charts. But for some reason I don't have "Chart" command at all and, accordingly, I cannot open charts of additional pairs. What is the problem here ?

Which fields to fill and which ones not? As far as I understand, it does not matter whether the position is long or short.

Use minimal code - use standard library:
