Need a script to change colours of the Bar UP and DOWN

Hi

As per the title, I need a script, that when it is applied to a chart, it changes the colour of the current bars UP and DOWN to a static colour (for eg. AQUA).

I would like it set up preferably with HOTKEYS to interchange between 2 colours. So for eg. pressing the key "1" (or any pre-set hotkey) will change the bars (both Bar UP and Bar DOWN) to AQUA colour (colour 2).; By pressing key "2" (or the second preset hot-key) the bars will change back to original colour (colour 1).

I know this can be done my simply saving them as 2 different templates - however, by changing templates, I loose all the other data (trendlines, horizontal lines, etc) that were set on the first chart. So what I have been doing, is manually changing the bar colours by Right clicking, selecting properties, on the colors tab, and changing the BAR UP and BAR DOWN manually.

Here is a visual example of what I want:

This is an example of my original chart - Bar UP and DOWN set to the value "NONE" - say this would be my colour 1:



Then by pressing Hot-Key 1, the chart would change to look like below - Bar Up and DOWN set to the value "AQUA" - say this would be my colour 2:



Then by pressing Hot-Key 2, the chart goes back to my original colour (value = NONE ... colour 1):



Hence i can switch between these 2 colours constantly by using my hotkeys. Can someone code such a simple script or EA or similar? Would be great, and make things so much easier - instead of changing between colours manually.

Thanks

can anyone help me with this please?

This can be done in MT5 quite easily, but not in MT4 using standard mql4

Sure it can. I use indicators instead of scripts but you can get up to 10 different colours if you use the buffers correctly. 8 with buffers and 2 from the original setting.

Just look for an indicator called rsi candles. That indicator changes colour of candles based on rsi reading. Just take the setcandle function out and put it in a script.

No, it paints over the top of the bar, it doesn't change the colour of the bar, it will work as long as you don't want to zoom in or out too much . . .

so in short I gotta do it manually everytime ?

Thanks for all your input fellas - I appreciate your time

Not quite true either...just change the histogram size based on the zoom factor.

But you are right in that it paints over the bar.

My point to @topdogg is that it can be done.

Even width 5 is not wide enough for the max zoom level, the others can be done though, but it's still a kludge and not what the OP was asking for. Maybe with the forthcoming changes to MT4 and the common MetaEditor we might be able to do things like this . . .


. . . don't hold your breath though.
