How to communicate with MMLs.

To get help from others, you might want to post your code. I'm one of the few willing to engage in abstract discussions.

OK, I'll create a demo code and post it here , if you didn't understand the problem. That's the least of my problems and I'll have it done in a few minutes. But you should promise me that you will find a solution to exactly what I require, not keep giving me your suggestions that don't solve the problem at all. Or at least you should admit that you don't know any solution (even that would be more useful than what you've written so far). If you're not capable of that, I won't bother with the code, because any slightly more experienced MQL programmer should understand the problem, and beginners can't be expected to solve it.

I decided to post the demo code so that no one can make excuses that they don't understand the problem and the problem is too abstract.

So there are two buffers in the indicator. And I require that the line be plotted at the bottom (so that it doesn't overplot the arrows), and that the name of the arrow buffer (in this case "Arrow", not "Line") appears in the info window (bubble) when you hover over the indicator.

I'm looking forward to a solution (from anyone), or confirmation that it can't be done (also from anyone).

And where's the line on the chart? Sometimes it's easier to admit I don't have a solution.

Maybe it was still too abstract. So I need to plot the line and the arrows. The line needs to be at the bottom so it doesn't overplot the arrows. At the same time, the bubble needs to display the arrow buffer.

Is this still too abstract???

I guess that I communicate better via code.😅

You're really funny. Or maybe it was still too abstract for you.

I'll leave aside the fact that your posted code doesn't work at all because it's missing an essential part. But I was able to complete the missing code. Unfortunately, you missed the point again. While your code now outputs the buffer values for the arrows to the bubble, the lines overplots the arrow on the chart (see the picture), which was mentioned in my request as undesirable. Try again, you don't have many other options. And then don't forget to post that you don't know the solution and we can end this comedy.

A good decision.

Since you didn't explicitly write that you don't know the solution, I have to ask you, where do you feel yourself to be in the graph below?

Don't worry at all about not knowing where you are on the Dunning-Kruger diagram. I have a pretty good idea about it, and I don't think I'm the only one.

Some might think that discussing programming problem with you was a waste of my time. But I don't think so. It's certain that you don't have the knowledge to be useful to help with programming, but you're a great entertainer.

Have a great day and I look forward to you making me laugh again sometime in the future.
