Change current bar color of a custom bar type

[chris07]

I am using a custom bar type where I do not have access to the code. I would like the current bar painted not green or red as it is painted by the proprietary bar type, but in another color. Is there a way to "overlay" the bar color with another one on the chart?

Hello chris07,

Thanks for your post.

Yes, with a custom script you can color the bars as you wish.

Please see the following methods that would allow you to color the bar and/or the outline of the candle

Paul,

thank you for the pointers! I have created a new indicator, but this changes the color of all previous candles, but not the current one:


// Sets the color of the current bar to transparent.
BarBrushes[0] = Brushes.Transparent;

the same thing happens when I use the sample code from the tutorial:

if (CurrentBar < 0)
return;

// Sets the color of the current bar to transparent.
BarBrushes[0] = Brushes.Transparent;

[chris07]

If I set

if (CurrentBar > 0)
return;

no color change is made to any of the bars.

(Sorry for the previous edits, I messed up and then corrected the > to < in the previous post)

Hello chris07,

Thanks for your reply.

If you are running the indicator with calculate.OnBarClose then [0] will be the current bar and the currently forming bar will not be known until it closes at which point your code will color that bar.

If you want to color the currently forming bar then you will need to change the script calculate setting to Calculate.OnPriceChange or Calculate.OnEachTick.

this code: if (CurrentBar > 0) return; Will not work because as soon as the 2nd historical bar is loaded to return. Return means don't do anything, so if the bar counter "CurrentBar" is greater than 0 (0 is the first bar of the data series) to then return and no further code is executed.

Hi Paul,

thank you for the explanations. I have set

Calculate = Calculate.OnEachTick;

however, now all the bars have their color changed.

[chris07]

This also happens on normal candlestick bars.

Will I need to tell it explicitly that all previous bars should have the original color?

Hello chris07,

Thanks for your reply.

It looks like you are setting the bar brush to transparent.

Can you clarify what you are intending?

[chris07]

The intention is to have the background color as bar color for the current bar. I could use white instead, but my background is set to an off white color. So I thought it would be more conventient to use transparent in case I change the background color.

[chris07]

I have changed Transparent to Yellow, and this colors all bars Yellow. So this does not seem to change anything.

Hello chris07,

Thanks for your reply.

I am probably misunderstanding what your goal is but here is what I see with your script, all bars transparent and just the outline remains.



If that is not what you are after, please elaborate on what you are wanting to see and/or post a screenshot that illustrates.

Hi Paul,

I would like to have only the current bar color set as transparent. All previous candles should have their original color (green or red, for instance).

[chris07]

It should look like this:

Hello chris07,

Thanks for your reply.

Please try:

if (State != State.Realtime)
return;

BarBrushes[0] = Brushes.Transparent;

if (Close[1] > Open[1])
{
BarBrushes[1] = Brushes.Green;
}
else
{
BarBrushes[1] = Brushes.Red;
}

Hi Paul,

this works perfectly. Thank you!

I am not sure though where the problem was exactly, except that there was something wrong with the previous bar color not assigned correctly. Could you explain briefly?
