Different Colour for Candle

is it possible to have green colour when the close is greater than open and a red colour when the close is less than the open while using candle

Please attach the image of your candle. I also don't know what "the close is greater than open" or "the close is less than the open" means. What does it mean??? Do you mean close like a verb to shut, as in a door, or close like meaning "nearby"? Actually neither seems to make sense in this context.

'candle' is part of Financial TB so open/close refer to stock ticker prices...it draws what the analysts refer to as a candlstick chart but I admit I know not of which they speak otherwise...

Oh, that's funny. Thanks for clearing it up. I thought it was an actual real candle. Now I understand.

Yeah, I could tell you were thinking "Image processing! My baliwick!", IA... :)

I do enough econometrics stuffs that have run across it; it's similar to box plot idea excepting for stock prices...

Well, the doc says "(Optional) Candlestick color is specified as a character vector." which would indicate you can with just a little effort...

clrs=char('r','g');  % the two-vector from which to choose
Color=clrs((ClosePrices>=OpenPrices)+1);  % select based on condition
candle(HighPrices,LowPrices,ClosePrices,OpenPrices,Color)

Make tri-state if want "no change" to show up as other than G as will here.

As noted, "air code", can't test as don't have requisite TB.

ADDENDUM

"Tri-state" is just a little different since a single logic comparison is only binary...

clrs=char('r','b','g');
Color=clrs(sign(ClosePrices-OpenPrices)+2);

-1,0,1 --> [1,2,3] ~ 1*sign(deltaPrice) + 2
