What can be used to draw objects with reference to axes rather than to price and time? Canvas is not an option.

And you have to look for the cross. I'm too lazy...

What is this? And how does this relate to building a TextLabel object with the required Wingdings font character code as text?

if he has a point on the axes ( time and price on the chart) he can put any of the symbols, but he has a task not on time and price...

So he'll have to do some calculations.

So Text mark. The font is Wingdings, and the code for the character you're looking for is in the Help file.

I have the code, so the text mark with the Russian text output on the Arabic computer looked like ??? ??? ????

Here's the question: won'tWingdings display squares instead of arrows, how reliable is this method for the language settings of the users' computer?

this character table is the same for everyone.

maybe not, looked on the internet, they are still divided by number, it's not clear....

I had one time it was different... so unreliable... Better to draw in photoshop and plug in resources

If you made one mistake with indexing, you won't redraw them in Photoshop for the rest of your life

they made a mistake once with the indexing, so we can't spend the rest of our days redrawing them in Photoshop

I didn't make a mistake, instead of the icons the customer had some fonts or letters... Maybe he didn't have Wingdings font installed... You can speculate as much as you like. The fact is, if you use this method, it's only targeted... I'm not talking about OBJ_ARROW, I'm talking about fonts that are like icons... There's like 4 or 5 fonts.

Decided to probably do it safely with OBJ_LABEL.

string Arrow = (label=="Flat"?"o":(label=="Divergence"?"x":">"));

The font is"Arial Black".

The end result is satisfying.
