Color Transparency in Rectangle Object

Since "angevoyageur" is also a moderator, if he has recommended the article to you, then it is because it is also relevant to MQL4+ (even if it is geared for MQL5).

Why don't you simply try out a few examples and find-out for yourself?

Currently MetaQuotes is slowly merging the two platforms into one, so learning the MQL5 way of doing things is only going to benefit you in the long run.

How did you do it?

I just refer the link and read the article. Use definition of transparent  C'0,0,0'/ 0x000000  as the visual effect which I want, but no transparent effect at all?

My compiling platform MetaQuotes 4  Version : 4.00 Build 1010    18 Aug 2016

Pls give me some adivce or hints! Thanks in advance!

Hi Alain,

I had the same question as the original post. I've read through that article in full, and my apologies if I've not understood it well enough, but I still can't see how to draw a transparent OBJ_RECTANGLE.

The article you've linked gives a great explanation for how to apply transparency (and much more) to CCanvas objects, but I'm trying to bind transparent rectangles to the chart, so that it would rescale and shift accordingly as users adjust the chart and new candles are plotted.

Can CCanvas objects be bound to the chart and shift out of view accordingly? I can only see how to plot them to the coordinates within the visible screen, independent of chart movements.

Thanks!
