I wrote an indicator that shows Open of current candle is equal to Close of previous candle. but I don't know how to change the color of High/Low shadow for bullish and Bearish candles.

Is it possible to change the color of each candle in for loop?

is it possible to change the color of High/Low shadow for bearish and bullish candle same as body?

I attach my .mq4 file please have look. it take just a second time.

You don't need an Indicator to change the colours of the candles (body or shadow). Just set them in the Properties (F8 -> Colors) of the Chart and then Save it as a Template (e.g. Default template):

Actually I need a kind of chart that Open of any Candle is equal to Close of Previous candle.

Hello

Actually I need a kind of chart that Open of any Candle is equal to Close of Previous candle.

I mean this type of candle

for(i=pos+1; i<rates_total; i++)
     {
      NewOpenBuffer[i]=close[i-1];
      NewCloseBuffer[i]=close[i]; 
      NewLowBuffer[i]=  MathMin(NewOpenBuffer[i],low[i]);
      NewHighBuffer[i]= MathMax(NewOpenBuffer[i],high[i]);      
                    
     }

I have 4 buffers for High-Open-Low-Close.


my External color:

input color ExtColor1 = Red;
input color ExtColor2 = LightSeaGreen;
 

and my SetIndexStyle:

   SetIndexStyle(0,DRAW_HISTOGRAM,0,1,clrWhite);
   SetIndexBuffer(0,NewLowBuffer);
   SetIndexStyle(1,DRAW_HISTOGRAM,0,1,clrWhite);
   SetIndexBuffer(1,NewHighBuffer);
   SetIndexStyle(2,DRAW_HISTOGRAM,0,3,ExtColor1);  
   SetIndexBuffer(2,NewOpenBuffer);
   SetIndexStyle(3,DRAW_HISTOGRAM,0,3,ExtColor2);

   SetIndexBuffer(3,NewCloseBuffer);


I just want to change the  color of shadows same to body of my candles. I don't know how to do that .

Take a look at the "Heiken Ashi" indicator provided by MetaQuotes. You will be able to learn how to do what you want from that code.

You will find the "Heiken Ashi.mq4" file in your "Indicators" folder.

To tell the truth I changed the heiken ashi chart to my own chart, 

Maybe I should define 6 buffer : 2 buffer for open and close with differrent colors and 2 buffer for high and 2 buffer for low

if close>open then it is a bullish and use the the buffer of high which is related to bullish color and so on and so forth.

Any idea??

Yes. Drop the Heiken Ashi, make it all one color and create objects

Objects ? What to do ? It's always better to use buffers.

Sorry to say this, but that is a very BAD choice for this case. He is recreating candle bars. Buffers is the RIGHT way to go and the Heiken Ashi is the example he should use.

@masoud0455_a: The Heiken Ashi I have only uses 4 buffers. All you have to do is substitute the calculations of the haOpen, haClose, haHigh and haLow for your own values that you wish to use.

The trick that is used in the Heiken Ashi indicator to getting the colours correct is to switch the High and Low values when the bar is in the opposite direction. So make sure you do not remove that functionality.
