(Request) How to code this simple command

[swordfish]

I want to start the EA at GMT 21 for a broker that is +3 GMT. You see, MT4 gets confused when GMT21 and +3 = 24 or zero.

extern int GMTOffset = 3;

extern int GMTStartHour = 21;

GMTStartHour = GMTStartHour + GMTOffset;

if (GMTStartHour >= 24)

{

GMTStartHour = GMTStartHour - 24;

}

GMTEndHour = GMTEndHour + GMTOffset;

if (GMTEndHour >= 24)

{

GMTEndHour = GMTEndHour - 24;

}

 

As a result, the EA won't start.

I apprecite it very much if you could give me a hint.

The code below with your gmt offset incorporated into the start & stop hour will work. And you don't have a problem with start time being greater than the end time.

 

 

//e.g. the ea will for run 4 hours between 10pm at night to 2am the next morning

//use 0 for midnight

extern int Hour_Start_Trade = 22;

extern int Hour_Stop_Trade = 2;

int gi_96 = 50;

 

if (IsTradeTime()) {your code to be run}

 

bool IsTradeTime() {

if (Hour_Start_Trade < Hour_Stop_Trade && TimeHour(TimeCurrent()) < Hour_Start_Trade || TimeHour(TimeCurrent()) >= Hour_Stop_Trade) return (FALSE);

if (Hour_Start_Trade > Hour_Stop_Trade && (TimeHour(TimeCurrent()) < Hour_Start_Trade && TimeHour(TimeCurrent()) >= Hour_Stop_Trade)) return (FALSE);

if (Hour_Stop_Trade == 0) Hour_Stop_Trade = 24;

if (Hour() == Hour_Stop_Trade - 1 && Minute() >= gi_96) return (FALSE);

return (TRUE);

}

Maven,

 

I assume the exmaple hours "22" and "2" are broker server time, not GMT time?

So in order to run GMT21-7 for server GMT+3, the server time should be 24 to 10 or 0 to 10?

Thank you so much.

Yes your assumptions are right. I would use 0 to 10 in your example. When backtesting with the code using 0 for midnight (instead of 24) definitely works.
