Here.

Good afternoon programmers gurus, help fix the autofib.

1. I want to change the stretching of Fibo, not from 0, but from 100, i.e. the stretching has to start from the last HI to LOW and from LOW to HI and start stretching from 100 level to the bar behind the price, like in autofibo, but vice versa. If the fibo has stretched HI or LOW, the fibo is reversed and coloured, if it is difficult to colour, let it stay that way.
2. switch the price channel on and off.
3. The possibility to add and modify levels in the code and at each level the price should be indicated, we need the level 23.6 and other levels.
4. At the moment of placing an order in the Fibo grid, Fibo stops stretching; after the order is processed, Fibo is removed. After the order has been processed, fibo is deleted.New fibo starts stretching; it is turned in the opposite direction and colored in another colour.

I would like to ask you to mark in the code what you have changed.

File attached....

Thanks in advance.

Artem could you write at least some example code, how it should look like?

[Artyom Trishkin]

Ruslan:
Artyom, maybe you could write at least some example code, how it should look like?

I could, but I won't. It's very simple. Read the help - it's very interesting.

When one is just starting to learn MQL, everything is not so easy for him, at least for me.
But thank you for such an answer.

Everyone is a beginner. I have given advice for myself.
