I can not change the bar color.

[nkhoi]

I tried to change bar color of fishertransform but it didn't take. I can change the background color but the bar color stayed the same. In this code I tried to change the bar color when it was above zero to green.

[nkhoi]

one more question;
this line return the current value:

double temp = FisherTransform( period )[ 0 ];

but this line make the indicator disappear, should it return the previous value instead?

//double temp1 = FisherTransform( period )[ 1 ];

        protected override void OnBarUpdate()
        {
			double temp = FisherTransform( period )[ 0 ];
		//	double temp1 = FisherTransform( period )[ 1 ];
			if(temp < 0)
			{		
				BackColor = Color.LightPink;     // set back ground color
				HistDown.Set(temp);
			}

			if(temp > 0)
			{
			    BackColor = Color.LightSeaGreen; // set back ground color
				HistUp.Set(temp);
			}

Your .cs had code errors. You should try in Initialize()

Add(new Plot(new Pen(Color.Green, 3), PlotStyle.Bar, "HistTickUp"));
Add(new Plot(new Pen(Color.Blue, 3), PlotStyle.Bar, "HistTickDn"));
Plots[0].Min = 0;
Plots[1].Max = 0;


and then later just

HistTickUp.Set(temp);
HistTickDn.Set(temp);

Can't answer your other Q cause I don't use the indicator.

thanks MM, now I have 2 colors. For the histogram above zero I also want to color it red if current histogram < prev histogram. This code compiled np but I got only green color.

		    if (fishValue > 0)
			{
			  BackColor = Color.LightSeaGreen; // set back ground color
			  if (fishValue > Value[1])
				  HistTickUp.Set(fishValue);
		      if (fishValue < Value[1])         
				  HistTickDn.Set(fishValue);
			}

include is a mock up histogram and cs file.

nkhoi, I would suggest adding a third 'neutral' color to activate when both your red / green colors conditions do not hit....

[marketmasher]

NT 6.5 requires a different Plot statement for every color change, so you would have to add 2 more plots and then .Set them with conditions in your code.

[nkhoi]

add 3 more color plots, still got only 2 color histogram as before.

			Value.Set(fishValue);
		    if (fishValue > 0)
			{
			   BackColor = Color.LightSeaGreen; // set back ground color
			  if (fishValue > fishPrev)
				  HistTickUp.Set(fishValue);
			  else 
		      if (fishValue < fishPrev)
				  HistTickUpDn.Set(fishValue);
			  else 
				   Neutral.Set(fishValue);
			}

From a quick glance you only set those color options for the Fisher to be > 0, not for the other way round.

[nkhoi]

yes, I work on hist bars > 0 condition first, they are all > 0 but are they slope up or slope down?

[NinjaTrader_Bertrand]

I suggest you then check into your fishPrev (print those to the ooutput window) values as they trigger the condition for plotting the histogram color changes.

[marketmasher]

For that you need 6 Plots 1)Above 0 and > prev fishvalue 2)Above 0 and < prev 3)Below 0 and > prev 4)Below 0 and < prev 5)Above 0 and = prev 6)Below 0 and = prev. If you get 1 working, copy and edit for the rest.

It doesn't like my coding that is all I can tell

	    if (fishValue > 0)
			{
		       Print(Time[0]+"   fish value:  "+ fishValue + "  fishPrev:  " + fishPrev);
			   BackColor = Color.LightSeaGreen; // set back ground color
			}	
			  if (fishValue > 0 && fishValue > fishPrev)
				  HistTickUp.Set(fishValue);
		
		      if (fishValue > 0 && fishValue < fishPrev)
				  HistTickUpDn.Set(fishValue);

nkhoi, it might be you can't see the color changes of the plots as the histograms overlap, have you using one bar style and one plot of linestyle in combination?

thanks, I see my error now plenty of fish value < 0 but not in negative I just auto assume that if it's < 0 then it's negative.

[NinjaTrader_Bertrand]

I'm not sure I follow your thought, < 0 would be negative
