BarsCalculated() return with error code 4806.

[tao zemin.]

I use the indicator attached to show a H4 moving average in H1 Chart.[by setting the period parameter to H4 in a H1 chart.] But nothing is shown in the chart. 

The function call BarsCalculated() returned with error code 4806. What is wrong with my code? How should i tackle this issue? thank you time and efforts.

Thank you foryour reply. the problem still exists. I modified the first parameter in the iMA() call directly to Symbol(). But the problem still exists. How should I write the Symbol() parameter?

   handle=iMA(Symbol(),period,ma_period,ma_shift,ma_method,applied_price);

do you have this symbol on your Market Watch window?

[tao zemin.]

Yes,the symbol is in the marke watch window. the symbol is:EURUSD. Have you run the indicator on your side? Is there any 4806 error? Thank you.

But, I don't have EURUSD on mysignal... but all other symbosl I tested, it ran with no errors or warnings...

;)

It's really wierd! Ihave updated my MT5 to it's latest version this morning, the problem still exists!

I' will continue to fight against this problem and helps from you and other experts in this website will be highly appreciated.... Thank you, Flavio.

House, please have a look at this code, I cant figure out what is wrong - it is not taking trade. it says "failed market buy 0.10 GBPJPY sl:145.247 tp:146.247 [Unsupported filling mode]"
