For Market in the sense of ?
then you have to build your own GUI library in your own image :-(
MQL is not intended for complex GUI. It is intended for counting and trading.
That is, it can be done, but it is excruciatingly stupid.
Decided to study CCanvas library
Can't figure it out - no errors (or rather, the compiler doesn't give any), and nothing on the screen either. I want to draw a red triangle ...
And here's the result
Decided to explore the CCanvas library
Thank you for the ready-made example
If you don't mind, can I have a few words about my mistakes? It's just that I was looking at the help on the website, and the documentation only has a description of the functions themselves, and the examples below which function is after which are not there

Good afternoon!!!
I want to try to write a function to remember losing orders by profit, lot and ticket.
I have never worked with arrays before, I have done it by example and by reference.
I do not know where and how to specify the array size.
Please check and correct if possible.

struct StructOrder
{
double OrProf;
double OrLot;
int OrTiK;
};
StructOrder OrBuy[];
StructOrder OrSell[];

double cur_profits_BUY = 0;

InitStruct_Order(OrBuy);
InitStruct_Order(OrSell);
//ArrayResize(OrBuy,bo);

Hi,
Could you please tell me how to build a project consisting of an mq4-file and a lot of mqh-files into one, for a marketplace ?
Friends, please help me to program a reversal indicator in my Expert Advisor through iCustom, which consists of one line, but with different colours for buy and sell. It has no arrows. For colour it seems to have three buffers, but in fact when held with mouse it shows only one Value1 for both colours. I tried both to compare bars and to compare with zero, it doesn't help. How to program reversals of such indicators, who knows? Here are the initial settings of indicator buffers and its picture. It looks like StepMA, but it is not:

Example
The indicator based on DRAW_COLOR_LINE. There are two indicator buffers - one for values ('ColorLineBuffer') and another one for colours (' ColorLineColors').
And the Expert Advisor, copies values from buffer number '0' ('ColorLineBuffer') and number '1' ('ColorLineColors').
