BarColor in multi-timeframe

[shooter]

Support/Josh

In a multi-timeframe strategy,the way one references the other timeframe bars is like Lows[0][0] or Highs[0][0]. But is there anyway to color the bars of lowertimeframe based on highertimeframe conditions.

Like if I do this in ninjascript it is not coloring bars in lower timeframe

===============
if (BarsInProgress == 1 ) // highertimeframe
{
if (condition1_in_higher_timeframe)
{
//color Bars in lower timeframe
BarColor = Color.Green;
}
}

=============

Should one do as below to reference lower timeframe barcolor while processing higher timeframe conditions.
BarColors = Color.Green;

or
BarColors[0] = Color.Green;

Shooter, which timeframe do base this and which timeframe do you add? BarColor would also work in your MultiTimeStrategy.

Bertrand, thanks for the reply.

But how do I refer to lower timeframe BarColor, when one is processing higher timeframe conditions? For example strategy is loaded on 1 min chart and the higher timeframe 5 min is added. While processing 5 mins bars, "BarColor" is referring to 5 min bar's color correct? How do I refer to 1 min Barcolor,..is it by "BarColor[o]", so that one can color 1 min chart based on 5 min timeframe?

Shooter,

Unfortunately programmatically accessing the colors is not supported. You can only set them.

If you want to see if it is a red/green bar just run the Opens[1][0] > Closes[1][0] check. If you are checking for a bar color set by a strategy/indicator, you should expose a property that states that such a color was set instead of actually checking bar color.

Josh,

Thanks for your reply. Just to clarify, I am not trying to access BarColor of lower timeframe, I am trying to set them. Basically trying to set the BarCOlor of timeframe bars based on condition set of higher timeframe bars.

===============
if (BarsInProgress == 1 ) // highertimeframe
{
if (condition1_in_higher_timeframe)
{
//color Bars in lower timeframe
BarColor = Color.Green;
}
}

=============
The above code ,when treid to not coloring 1 min Bars, the chart on which it is loaded.

shooter, just tried this simple snippet on the ES and it plotted correctly -

 
if (Closes[1][0] > SMA(BarsArray[1], 20)[0])
{
BarColor = Color.Blue;
}

[shooter]

Thanks Bertrand. But if one processes higher timeframe bars and adds the line
if (BarsInProgress == 1 ), before the code, its not processing the lower timeframe barcolor

 
if (BarsInProgress == 1 )
{
   if ( Close[1][0] > SMA(20)[0] ) //processing bars in 5 min chart
    {
      BarColor = Color.Blue;  //should color bars in 1 min chart if it works
    }
}

or am I missing something obvious here.

I'm not sure I follow, when you intend to color the primary bars object you should check for BarsInProgress == 0 - the higher timeframe condition is already expressed in working with BarsArray[1]. Just rechecked and works on my end.

[shooter]

Thanks Bertrand and Josh. Appreciate it.

I was processing BarsinProgress=1, for higher timeframe and was somehow trying to make the lower timeframe bars colored while processing highertimeframe bars. Looks like the only way to set the lower timeframe barcolor is to use,BarsinProgress==0 and then set BarColor accordingly. Will try that.
