Question about programming AMA logic into an EA

zeroz · #1 (**permalink**) 12-02-2006, 08:22 PM

How would I go about creating an EA using the AMA(Kaufman) that enters positions on the bar after a colored ball appears? Do I need to put the AMA logic into the EA or should I be using global variables? I have a bit of programming knowledge, however in my tests using a global variable the EA only trades in one direction.

The logic in the indicator that I think identifies whether a ball appears or not is :

if ((MathAbs(ddK)) > (dK*Point) && (ddK > 0)) kAMAupsig[pos]=AMA; else kAMAupsig[pos]=0;
if ((MathAbs(ddK)) > (dK*Point) && (ddK < 0)) kAMAdownsig[pos]=AMA; else kAMAdownsig[pos]=0;

So what I did was put " datetime AMASig = GlobalVariableSet(string "AMASig", double ddK);" into the indicator to pull out the ddK. Then, in the EA I put:

if ((MathAbs(ddK)) > (dK*Point) && (ddK > 0))sig=1;
if ((MathAbs(ddK)) > (dK*Point) && (ddK < 0)) sig=2;

Where sig 1 is a buy and sig 2 is a sell, however the problem I described above persists. The EA only trades in one direction.

Thanks for any help!

Pictures and indicator attached.

i dont know how to start, but if i make some EA from indicator like AMA or another, i would use iCustom....

PHP Code:


			
extern int shift=1;



//indicator setting

int       periodAMA=9;

int       nfast=2;

int       nslow=30;

double    G=2.0;

double    dK=2.0



//define some signal

#define SIGNALBUY 1

#define SIGNALSELL 2

.

.

int Order;



//indicator



double AMAUpNow = iCustom(Symbol(),0,"AMA",periodAMA,nfast,nslow,G,dK,1,shift);

double AMAUpPrev = iCustom(Symbol(),0,"AMA",periodAMA,nfast,nslow,G,dK,1,shift+1);

double AMADnNow = iCustom(Symbol(),0,"AMA",periodAMA,nfast,nslow,G,dK,2,shift);

double AMADnPrev = iCustom(Symbol(),0,"AMA",periodAMA,nfast,nslow,G,dK,2,shift+1);



if(AMAUpPrev==0 && AMAUpNow !=0 && AMADnNow==0)

Order=SIGNALBUY;



if(AMAUpNow == 0 && AMADnPrev==0 && AMADnNow!=0)

Order=SIGNALSELL;

i hope this help u, but sorry i write this with notepad, so i don't know that any sintax was wrong....
sorry for my bad english, but if anyone here speak indonesian that would help

Ah, yea. I didn't see that I could use the independent buffers through the iCustom function. Using the global var was a bit convoluted. Thanks!
