in mql4, i can use iTime[1] to get bar[1] opentime ,
in mql5 , i use below sentence
CopyTime(Symbol(),PERIOD_CURRENT,1,1,from);
but i get compile error:
no one of the overloads can be applied to the function call
how to solve
thanks
oh, i knew the mistake i commit : wrong parameter type that i decl"are
"from" should be datetime array , not double
in mql4, i can use iTime[1] to get bar[1] opentime ,
in mql5 , i use below sentence
CopyTime(Symbol(),PERIOD_CURRENT,1,1,from);

My guess is that the variable 'from' is not declared properly
datetime from[1];
// or, if 'from' will be used for variable numbers of bars in other CopyTime calls
datetime from[];
Hi,
I can't see a place to open a new topic so I'll ask here. This code was working in MQl4 and I'm trying to convert to MQL5. I've read the conversion articles, searched, and modified it a bit yet I'm still getting error messages.
objectsetdouble : "no one of the overloads can be applied to the function call" (this was also on the second ObjectSet until I changed it to 'integer').
It also seems to be necessary to add 'Return(0);' or something like that, which wasn't necessary in MQL4 when the function was only used for ex drawing on the chart and not calculating a value to return.
int draw(string symbol, int _, int window, int shift, double value, color colour, int code){ string draw; StringConcatenate(draw,value,shift); datetime Time[]; datetime time = Time[shift]; ObjectCreate(0,draw,22,window,time,value); ObjectSetDouble(0,draw,OBJPROP_COLOR,colour); ObjectSetInteger(0,draw,OBJPROP_ARROWCODE,code); return(0);} int trend(string symbol, int _, int window, int shift_1, double price_1, int shift_2, double price_2, color colour){datetime iTimeMQL4(symbol,_,shift_1); string trend; StringConcatenate(trend,price_1,shift_1,price_2); datetime time_1 = iTimeMQL4, time_2 = iTime(symbol,_,shift_2); ObjectCreate(0,trend,OBJ_TREND,window,time_1,price_1,time_2,price_2); ObjectSetDouble(0,trend,OBJPROP_COLOR,colour);}
for the second function I tried to replace iTime with iTimeMQL4 but I get 'class type expected', so if someone could tell me how to replace iTime from MQL4 that would be appreciated.

Does changing the function definition to void make a difference?
If you are not expecting a returned value from the function, perhaps this will work:
void draw(string symbol, int _, int window, int shift, double value, color colour, int code){ string draw; StringConcatenate(draw,value,shift); datetime Time[]; datetime time = Time[shift]; ObjectCreate(0,draw,22,window,time,value); ObjectSetDouble(0,draw,OBJPROP_COLOR,colour); ObjectSetInteger(0,draw,OBJPROP_ARROWCODE,code); return(0);} void trend(string symbol, int _, int window, int shift_1, double price_1, int shift_2, double price_2, color colour){datetime iTimeMQL4(symbol,_,shift_1); string trend; StringConcatenate(trend,price_1,shift_1,price_2); datetime time_1 = iTimeMQL4, time_2 = iTime(symbol,_,shift_2); ObjectCreate(0,trend,OBJ_TREND,window,time_1,price_1,time_2,price_2); ObjectSetDouble(0,trend,OBJPROP_COLOR,colour);}
