How to integrate an Indicator into an EA?

Hi all,

I have an EA which is working based on a custom indicator. I have their source code.
I'm curious if it's possible to integrate the code of the indicator into the EA? Which means the EA could work by itself and the indicator could be thrown away.
I tried to do so but unsuccessful till now. I don't know how to deal with indicator specific functions like IndicatorCounted, Bars, Low, High. They just don't work in EA.
Could someone who has experience with this share some knowledge with me? Any comments or suggestions are welcome. I'm much appreciated.

Thanks
Sarran

You have to have the indicator in your platform for the EA to work, but not sure if it has to be attached to the chart you are running it on for it to work. However, if you don't understand the parameters of the indicator, you shouldn't be trading with the EA. Besides if the indicator doesn't work with the EA, how can the EA perform properly?

you do not have to have the indicator on the chart you are using for the ea... you merely have to reference it within the ea.... which i assume is referenced or it would not be working.... just like you can use the ma within an ea without it being on the chart...
why throw it away anyway... just let it set in the directory...

Thanks for your replies.
However, I don't think you understood my requirement.
I know I can put the indicator in the indicator directory and make the EA use it through "icustom" function. But what I need is to rewrite the indicator code into the EA so the EA could work by itself. So that to let others use my EA, I just need to send them the EA without sending the indicator together.

OK, this is a tough one that I haven't tackled before.. but will try...
not knowing what the indicator does, let us assume it combines the stochastic of a lot of currencies and presents it in the chart window.
You can throw away all the property indicator colors, the indicator name, the setindexstyle, setindexbuffer, then set up a loop with about 300 bars like so:
(of course you need to declare all variables).
string usd[6]={"GBPUSD","USDJPY","EURUSD","AUDUSD","USDCHF","NZDUSD","USDCAD"};
string eur[4]={"EURUSD","EURGBP","EURCHF","EURJPY","EURAUD"};
string gbp[3]={"GBPUSD","GBPJPY","GBPCHF","EURGBP"};
string jpy[2]={"USDJPY","EURJPY","GBPJPY"};
string chf[2]={"EURCHF","GBPCHF","USDCHF"};
for(int i=0; i<300; i++)
{

eurd=0;
eurk=0;
usdk=0;
chfk=0;
gbpk=0;
jpyk=0;
chfd=0;
gbpd=0;
jpyd=0;
usdd=0;
for(x=0; x<5; x++) {
eurk=eurk+iStochastic(eur[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i);
eurd=eurd+iStochastic(eur[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i);

}

for(x=0; x<4; x++) {
if(StringFind(gbp[x],"GBP",0)==0){
gbpk=gbpk+iStochastic(gbp[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i);
gbpd=gbpd+iStochastic(gbp [x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i);
}
if(StringFind(gbp[x],"GBP",0)==3){
gbpk=gbpk+(100-iStochastic(gbp[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i));
gbpd=gbpd+(100-iStochastic(gbp[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i));
}

}
for(x=0; x<3; x++) {
jpyk=jpyk+(100-iStochastic(jpy[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i));
jpyd=jpyd+(100-iStochastic(jpy[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i));
chfk=chfk+(100-iStochastic(chf[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i));
chfd=chfd+(100-iStochastic(chf[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i));
}

for(x=0; x<7; x++) {


if(StringFind(usd[x],"USD",0)==3){

usdk=usdk+(100-iStochastic(usd[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i));
usdd=usdd+(100-iStochastic(usd[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i));
}
if(StringFind(usd[x],"USD",0)==0){
usdk=usdk+iStochastic(usd[x],0,5,3,6,MODE_SMA,0,MODE_MAIN,i);
usdd=usdd+iStochastic(usd[x],0,5,3,6,MODE_SMA,0,MODE_SIGNAL,i);

}

}

##### now the items below assign the lines to certain parameters, which you will need to pull off and use within the ea....
the ak[i] for instance would be the usd/something.. so you might say:
if(ak[i] == 45) {selldollar();} etc.....

if(StringFind(Symbol(),"USD",0)==0) {ak[i]=(usdk/7);}
if(StringFind(Symbol(),"USD",0)==0) {ad[i]=(usdd/7);}
if(StringFind(Symbol(),"USD",0)==3) {bk[i]=(usdk/7);}
if(StringFind(Symbol(),"USD",0)==3) {bd[i]=(usdd/7);}
if(StringFind(Symbol(),"EUR",0)==0) {ak[i]=(eurk/3);}
if(StringFind(Symbol(),"EUR",0)==0) {ad[i]=(eurd/3);}
if(StringFind(Symbol(),"GBP",0)==0) {ak[i]=(gbpk/4);}
if(StringFind(Symbol(),"GBP",0)==0) {ad[i]=(gbpd/4);}
if(StringFind(Symbol(),"GBP",0)==3) {bk[i]=(gbpk/4);}
if(StringFind(Symbol(),"GBP",0)==3) {bd[i]=(gbpd/4);}
if(StringFind(Symbol(),"JPY",0)==3) {bk[i]=(jpyk/3);}
if(StringFind(Symbol(),"JPY",0)==3) {bd[i]=(jpyd/3);}
if(StringFind(Symbol(),"CHF",0)==3) {bk[i]=(chfk/3);}
if(StringFind(Symbol(),"CHF",0)==3) {bd[i]=(chfd/3);}
}
//----
return(0);
}

Did that help some??
