# Doubt with multi time frame!!

Hi,

I'm learning to program. I already used several functions, but now I want to know how to program multi time frame indicators. For example, how I can get signals fractals "m15" in "m5" (current time frame)?

I do not know how to work with functions of time or bars.

If anyone can tell me how I can start would appreciate.

Thank you very much

Use iBarShift()

```   int shift = iBarShift(NULL,PERIOD_M15,Time[i]);
double fractal_upper = iFractals(NULL,PERIOD_M15,MODE_UPPER,shift);
```

The indicator shows no sign:

You have to declare an array and assign it to a buffer.

```#property copyright "Copyright 2013, MetaQuotes Software Corp."
#property version   "1.00"

#property indicator_chart_window
#property indicator_buffers 1

double fractal_upper[];
//+------------------------------------------------------------------+

//+------------------------------------------------------------------+
init()
{
SetIndexBuffer(0,fractal_upper);
SetIndexStyle(...
}
//+------------------------------------------------------------------+
//| Custom indicator iteration function                              |
//+------------------------------------------------------------------+
int start()
{
int counted_bars=IndicatorCounted();

if(counted_bars>0)
counted_bars--;
int limit=Bars-counted_bars;

for(int i=0;i<limit;i++)
{

int shift=iBarShift(NULL,PERIOD_M15,Time[i]);

fractal_upper[i]=iFractals(NULL,PERIOD_M15,MODE_UPPER,shift);

}
return(0);
}

The reason for the 3 arrows appearing is because one candle in M15 is 3 candles in M5?

Only to learn, there is a solution?
How to manage time in this situation ?.

Thank you very much pidPod

I try to use the iCustom iBarshift indicator, but no signal.

The fractalsUp, in current time frame indicator works correctly, but if I try to display signs of "m15" in "m5", I have no signal.

fractalsUp[i]=iCustom(NULL,PERIOD_M15,"fractalsUp",Equals,nLeftUp,nRightUp,nLeftDown,nRightDown,0,shift);

The fractalsUp, in current time frame indicator works correctly, but if I try to display signs of "m15" in "m5", I have no signal.

I'll have to see your fractalsUp indicator to know where the problem is.

fractalsUp run correctly in current time frame:

So I think, the problem is in the code of last message.

Try using iBarShift() in fractalsUp instead?

I send you a PM,

I try but   I continued without signal
