Another question is for the multi time frame code would one only get the latest signal represented in a higher time frame? i.e. would the latest 30m signal be represented in the 4h chart or would it draw all over one another? From 4h to 30m i'm sure there is no trouble

For reference sake i'm trying to code for whenever the stochastic crosses the 0 line

((sm1>ss1&&sm2<ss2) || sm1==0) is about as far as i've gotten but no cigar. It needs to refer to a previous higher value obviously, going to hunt for a stochastic indicator that shows this

I don't suppose anyone could help me out in where the ibarshift has to be declared first and then what it has to be applied to? I would assume it has to apply to the signal when painted however it could just as easily be attached to all the minor indicators.

Sort of stuck and out of several forums I haven't found any helpful threads Re: Making an MTF

I want to know sth about fractals.D o we see the nonrepaitable fractal narow as the bar closes or 2 nd bar closes.And can we make an EA like buy or sell at that time when arrow seen onthe close of second bar.My question is same for SHİ non paintable alerts also.And what is the most convenient method to make an EA with these indicators .

Ok well I believe that

Inserted Code
 int i,imax,counted_bars=IndicatorCounted();
 double ao1,ac1,ao2,ac2,sm1,ss1,sm2,ss2;
 if(counted_bars>0) imax=Bars-IndicatorCounted();
 else imax=Bars-1; 
 
 for(i=imax;i>=0;i--)

needs to be replaced with


Inserted Code
   datetime TimeArray[];
   int    i,limit,y=0,counted_bars=IndicatorCounted();
   // Plot defined time frame on to current time frame
   ArrayCopySeries(TimeArray,MODE_TIME,Symbol(),TimeFrame);
//----
   limit=Bars-counted_bars;
   for(i=0,y=0;i<limit;i++)
     {
      if (Time[i]<TimeArray[y]) y++;


Am I getting warmer? some direction woudl be fantastic

Yes, I suppose that's one way to do it, although I would've used what I originally suggested (iBarShift), since it's more efficient. Same idea, though.

Now, just use your index "y" in your indicator's shift variable to find the appropriate indicator values. Don't forget to use your custom timeframe (looks like your parameter "TimeFrame") in the indicator's timeframe variable, too.

Well obviously i'd prefer the simple method

Inserted Code
 datetime some_time=D'2004.03.21 12:00';   int      shift=iBarShift("EUROUSD",PERIOD_M1,some_time);   Print("shift of bar with open time ",TimeToStr(some_time)," is ",shift);

So I can just use this? Obviously it seems like less code, yay for me.

Does this not rely on any other code and can be used for my expressed purpose?

Yup - that's the idea, although in your example, you use a fixed reference date.

For a more general solution, you can use
Inserted Code
some_time=Time[i]
and cycle through previous bars (by looping through i, for instance).

  • Jun 29, 2008 1:16pm Jun 29, 2008 1:16pm
datetime some_time=Time[i]
int shift=iBarShift(NULL,PERIOD_H4,some_time);
Print("shift of bar with open time ",TimeToStr(some_time)," is ",shift);

Getting a 'shift variable not defined' error.

Again I admit to complete ignorance and please be aware I am merely trying to logically assess what goes where with no reference point because I don't have any examples to work from.

Inserted Code
int start() 
{
 int i,imax,counted_bars=IndicatorCounted();
 double ao1,ac1,ao2,ac2,sm1,ss1,sm2,ss2;
 if(counted_bars>0) imax=Bars-IndicatorCounted();
 else imax=Bars-1; 
 
 datetime some_time=Time[i]
 int shift=iBarShift(NULL,PERIOD_H4,some_time);
 Print("shift of bar with open time ",TimeToStr(some_time)," is ",shift);
 
 for(i=imax;i>=0;i--)

Fairly sure that is where I dump this code as the other variables are declared here also. Again I could be wrong.

I'm just not sure why i'm getting a 'shift variable not defined error

One problem is that your positioning leaves the shift index i out of the loop. That is, if you're looping over i to determine your shift, put all commands which use i inside of your loop. The way you have it, it is outside.

It should be more like this:

Inserted Code
 
int start() 
{
 int i,imax,shift,counted_bars=IndicatorCounted();
 datetime some_time;
 double ao1,ac1,ao2,ac2,sm1,ss1,sm2,ss2;
 
 if(counted_bars>0) imax=Bars-counted_bars;
 else imax=Bars-1; 
 
 for(i=imax;i>=0;i--)
 {
  some_time=Time[i];
  shift=iBarShift(NULL,PERIOD_H4,some_time,false);
  Print("shift of bar with open time ",TimeToStr(some_time)," is ",shift); 
 
  ... etc ...
 
 }
 return(0);
}

I'm trying to add parabolic SAR and I borrowed the code from another thread

double sar1 = iSAR(NULL, time_frame_for_signal, psar, max, 0);
double cl1 = iClose(NULL, 0, 0);

double sar2 = iSAR(NULL, time_frame_for_signal, psar, max, 1);
double cl2 = iClose(NULL, 0, 1);

if cl1>sar1 itl enter exactly on the dot, and always after

if cl1>sar1 && cl2 <sar2 itl only trade the bar of the exact signal


it just doesn't seem to register when I put the code in the buy/sell signal as an additional parameter.

Any hints?

as for adding the ibarshift thing I sorta gave up and felt it just easier if I duplicate the indicator, give different style signals for different time frames so I could distinguish them and tell metatrader to show the required indicator for that time frame

Another quick question is does anybody know of the existence of a time period section highlighting sort of indicator? i.e. if I want to see the trade for every first friday of the month or only between tue-thur

Doesn't have to really give me any figures for it, it's just a visual aid i'm searching for.

Used the forum search function and did not seem to have much luck.

I would have thought metatrader have that function built in

Hi Omniferum, you could use ObjectCreate(); and ObjectSet(); to create a vertical line or rectangle object to highlight what you want highlighting, cant remember the parameters to those functions off top of head but look in the library section off metaeditor for them under object functions.

i'd have to type in every single time frame though, I only want the visual aid for backtesting
