what parameters to pass to icustom() function ? - page 2

New comment
 

I have examine my EA code but cannot pinpoint the bugs.the EA does not open order.Although the code for order opening,order closing etc is freely available codes,the trade criteria is mine which I visually test should be profitable provide one find the correct LRLPeriod value alongwith with correct stoploss management.i compile the EA but it does not show error but it is not opening position.here I am attaching for anyone to correct it and make it working and required that the fully working version may be used freely by all interested.Hoping for contributions from all forum members.Tnx

one more thing to add here.i use this code on the LRL Indicator given on 1st page and the Alert works fine.Why then EA is not working?.you can include this code in the indicator and see for yourself..

 
          //check to buy
            if(Close[1]>LRLBuffer[1] && Close[2]<LRLBuffer[2] && Close[1]>Open[2])
               {
                  if(Bars!=TOPB){
                        Alert("LRSig Buy",Symbol()+"-",Close[1]);
                        Print("LRSig Buy",Symbol()+"-",Close[1]);
                        TOPB=Bars;
                                }
               }
         
         //check to sell
            if(Close[1]<LRLBuffer[1] && Close[2]>LRLBuffer[2] && Close[1]<=Open[2])
              {
                  if(Bars!=TOPB){
                        Alert("LRSig Sell",Symbol()+"-",Close[1]);
                        Print("LRSig Sell",Symbol()+"-",Close[1]);
                        TOPB=Bars;
                                }
              }
 
I gave you a circular link because YOU already provided the code for YOUR question.
LRLBuffer[1]=iCustom(NULL,0,"Linear Regression Line",LRLPeriod,0,1);
LRLBuffer[2]=iCustom(NULL,0,"Linear Regression Line",LRLPeriod,0,2);

Yep,you are right but initially there was some confusion on the shift value till deVries point it out.Thats why.btw pls check the EA on why it is not sending order yet.i think

you can find it out.that ll be welcome :D

 

are my comments moderated.i remember putting up the print records on the journal which shows the error when I run the already mentioned EA but I don't see it now.if so why??

ok.lol.but someone must hv done it.i sure see it after pressing the button...im re-putting it up here.RaptorUK,pls llok into the code and tell me where it at fault.is it that the LRLBuffer values are not return by the indicator?.Does indicator need to explicitly return values for icustom to work? or it need not return.Inserting Alert code as given earlier is working and give Alert as expected.so then why replacing the place of Alert code with oredersend code is not working?

I retest it again without changing any code and gives this results!

iCustom() reads the Indicator's buffer(s), in this case, buffer.


double LRLBuffer[]

is an array of size zero elements, so any value you use from that array . . .

for(int i=4-1;i>=0;i--) //or   (int i=0;i<4;i++)
   {
   LRLBuffer[i]=iCustom(NULL,0,"Linear Regression Line",LRLPeriod,0,i);
   }

. . . will be zero. Either declare it with a fixed size or resize it . . .

RaptorUK! thnks to you the EA works now like magic after resizing although I first doubt it!

the graph is not nice though but thts not wht I expect initially.ll need to incorporate

stoploss feature and few filters to make it acceptable atleast.ll come to you when I encounted

roadblock again in future! :D
