functions

hi...

in MQL4 funtion can return array?

like

double *MyFunc()

{

double A[];

// make A calculationhere

return(A);

}

[MANSTIR]

are my calculation is correct?

double yesterdayHigh = iHigh(NULL, 0, Current + 1);

double yesterdayLow = iLow(NULL, 0, Current + 1);

double yesterdayClose = iClose(NULL, 0, Current + 1);

double pivot = (yesterdayHigh + yesterdayLow + yesterdayClose) / 3;

double todayOpen = iOpen(NULL, 0, Current);

double todayGap = (todayOpen - pivot + pivot); <---it's correct?

TakeProfit = MathAbs(todayGap);

please help me?

Yes of course.

Can calculate different arrays.

Something like:

for(i=0; i<limit; i++)

MACDBuffer=iMA(NULL,0,FastMA,0,MA_Method,Applied_Price,i)-iMA(NULL,0,SlowMA,0,MA_Method,Applied_Price,i);

//---- signal line counted in the 2-nd buffer

for(i=0; i<limit; i++)

SignalBuffer=iMAOnArray(MACDBuffer,Bars,SignalEMA,0,MA_Method,i);

MANSTIR:
double yesterdayHigh = iHigh(NULL, 0, Current + 1);

double yesterdayLow = iLow(NULL, 0, Current + 1);

double yesterdayClose = iClose(NULL, 0, Current + 1);

double pivot = (yesterdayHigh + yesterdayLow + yesterdayClose) / 3;

double todayOpen = iOpen(NULL, 0, Current);

double todayGap = (todayOpen - pivot + pivot); <---it's correct?

TakeProfit = MathAbs(todayGap);

please help me?

My choice would be:

double todayGap = 2*pivot+todayOpen; <---it's correct?

MANSTIR:

do any source code is suitable on above calculations instead of mine?

please change anything inside the ea, please... i'm not a good programmer

thanks

here's the ea

Sorry, EA code? maybe here.

Find Trend based on last 2 bars

Hi all,

I'm just learning MQL and would like to know the easiest way to find out if a trend is going long or short based on the last 2 bars.

For example, if the close price is 1.2345 for Close[2] and the close price is 1.2350 for Close[1], and the current Close price is 1.2360 for Close[0].

Would I do something like

if(Close[2] < Close[1] && Close[1] < Close[0]) {

}

and do the same for a down trend but reversed

Or is there a more professional way to do it.

Thanks for your help

What do you mean by "professional way"?

Every coder has a different logic and different way to code their ideas.

And the simpler is better! I think your code is quiet simple, I don't know how to make it simpler.

Yes of course.

Something like:

well Linuxser... i have this idea for code

int start()

{

double A = iMAOnArray(GetArray(1),10,5,0,MODE_EMA,0);

double B = iMAOnArray(GetArray(2),10,5,0,MODE_EMA,1);

Print("A= ",A," B=",B);

return(0);

}

double *GetArray(double Factor) // how to define a funcion return as array

{

double Arr[10];

for(int i=0;i<10;i++) Arr = i*Factor;

return(Arr);

}

this code is possible?

if yes, think, a lot of way for systems....

I thought there may be a function already in MQL that does this and I have not found it yet.

Thanks for your reply, much appreciated.
