Hello!

I wonder if it is possible to modify the default candle plot parameters in such a way (or to assign the property to the chart object) so that the candles are plotted in the following format:

Down candles are red And up candles are green.

Example of the stock chart can be found here:

I modified the default Black candle stick chart in the chart editor by changing the patch face colors. I wonder if this can be done from the scrip???

Thanks!

Something like that:

load disney.mat
candle(dis('3/31/98::4/30/98'))
title('Disney 3/31/98 to 4/30/98')
ch = get(gca,'children');
set(ch(1),'FaceColor','r')
set(ch(2),'FaceColor','g')

Hi!

This does not work anylonger.

Is it possible to define colors for Bullish/Bearish candles?

In addition, is it possible to conditionally change the candlestick face colors?

Try seprating bullish and bearish candles into two sets. Then plot each with diffrent colours. Here is quick and dirty example.

bullishColor = 	[0.4660 0.6740 0.1880]; bearishColor = [0.8500 0.3250 0.0980]; % Candle Colors
ii=0; iii=0;                
                    for i = 1:size(CurrentChart,1)
                      if CurrentChart{i,"Close"} >= CurrentChart{i,"Open"}
                        ii=ii+1; IndxBull (ii) = i;
                      else
                          iii=iii+1; IndxBear (iii) = i;
                      end
                    end
 
                    if ~exist('IndxBear', 'var') || ~exist('IndxBull', 'var')
                      continue
                    end
                    bullishCandles = CurrentChart (IndxBull,:);
                    bearishCandles = CurrentChart (IndxBear,:);
                                        
                    candle (bullishCandles, bullishColor); 
                    hold on 
                    candle (bearishCandles, bearishColor);
                     hold off
