Dearest MLADEN,

thanks boss,so in this case,code might be like this ? please correct me,

regards

===================================================================

original "simple MA cross EA" code

//

#define _doNothing 0

#define _doBuy 1

#define _doSell 2

int start()

{

int doWhat = _doNothing;

double diffc = iMA(NULL,0,Ma1Period,0,Ma1Method,Ma1Price,BarToUse) -iMA(NULL,0,Ma2Period,0,Ma2Method,Ma2Price,BarToUse);

double diffp = iMA(NULL,0,Ma1Period,0,Ma1Method,Ma1Price,BarToUse+1)-iMA(NULL,0,Ma2Period,0,Ma2Method,Ma2Price,BarToUse+1);

if ((diffc*diffp)<0)

if (diffc>0)

doWhat = _doBuy;

else doWhat = _doSell;

if (doWhat==_doNothing) return(0);

//

================================================

altered this way

#define _doNothing 0

#define _doBuy 1

#define _doSell 2

int start()

{

int doWhat = _doNothing;

double diffc = iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma1Period,Ma1Price,2,0 ,0,BarToUse)

-iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma2Period,Ma2Price,2,0 ,0,BarToUse);

double diffp = iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma1Period,Ma1Price,2,0 ,0,BarToUse==2)

-iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma2Period,Ma2Price,2,0 ,0,BarToUse==2);

if ((diffc*diffp)<0)

if (diffc>0)

doWhat = _doBuy;

else doWhat = _doSell;

if (doWhat==_doNothing) return(0);

//

=====================================

Replace this :

double diffp = iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma1Period,Ma1Price,2,0 ,0,BarToUse==2)

-iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma2Period,Ma2Price,2,0 ,0,BarToUse==2);[/PHP]

with this :

[PHP]double diffp = iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma1Period,Ma1Price,2,0 ,0,BarToUse+1)

-iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma2Period,Ma2Price,2,0 ,0,BarToUse+1);

ADX Filter help

Hi Pro-Coders,

I would like to implement an ADX filter which shall filter sideways choppy market conditions.

If the ADX is below 25 it should not open trades, I have coded this simple filter:

extern int ADXPeriod=14;

double CurrentADX = iADX(Symbol(),0,ADXPeriod,PRICE_CLOSE,MODE_MAIN,0);

double PreviousADX = iADX(Symbol(),0,ADXPeriod,PRICE_CLOSE,MODE_MAIN,1);

bool ADXfilter=false;

if(CurrentADX>25&&PreviousADX<25)

{

ADXfilter=true;

}

if(ADXfilter=true)

{

BUY();

.

.

SELL();

}

[/CODE]

For some reason the filer is not working. I have put the ADX filter before placing the buy / sell order.

Also putting it to the entry conditions signal is not working.

[CODE]

if(ADXfilter=true && MAFIB=="true" && BUY=="true")

Could someone please advise? Thank you in advance!

Your condition will work only when adx crosses level 25 on a current bar

Use simply this instead :

if(CurrentADX>25) ADXfilter=true;

Replace this :

double diffp = iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma1Period,Ma1Price,2,0 ,0,BarToUse==2)

-iCustom(NULL,0,"Hull parabolic 2.1",PERIOD_CURRENT,Ma2Period,Ma2Price,2,0 ,0,BarToUse==2);[/PHP]

You can delete the ma methods from there. They are not needed any more at all

Dear All,

I am looking for the sigmoid function in mql4.This is what I found so far:

//--------------------------- sigmoid() ---------------------------------

// 1/(1+exp(-x))

double sigmoid(double x)

{

if (x>50) return (1);

if (x<-50) return (0);

return (1.0/(1.0+MathExp(-x)));

}//sigmoid()

https://www.mql5.com/en/code/9002 and this debate neural network - Fast sigmoid algorithm - Stack Overflow

Can anyone help?Thanks.
