How does it (indicator) manage to do that? Can I see the code? What are the objects and how does it create them...?

The indicator draws dots and arrows (no source) :

Well, I need to delete all graphical objects created by this indicator on the chart. How can I do it, ifObjectFind() returns 4202?

iCustom() is not suitable for this purpose, if I understand correctly

Hello, esteemed specialists of this forum. I set out to create an indicator that shows the maximum equity drawdown.

The calculation is as follows:

double de;
double dw;

if (AccountProfit() < 0)
{
de = (AccountProfit() * (-1) * 100) / AccountBalance();
} else de = 0;

if (de > dw)
dw = de;

Print value of dw. All it shows correctly, but there are problems: 1 - when changing timeframe starts calculation anew, when restarting the terminal it zeroes out, when starting the indicator on another chart it also zeroes out.

What can I do to make the maximum equity drawdown indicator update when it reaches a new maximum and maintain the value under the above conditions?

There are no objects. There are indicator buffers. You can assign a background colour to them

Is it possible to put an AccountEquity() indicator that works in real time on the chart? Where can I get it?

Unexpected. In principle, if there are arrows on the chart, but they are not in the list of objects, it is logical that this means that the arrows are not objects. How can it be implemented through indicator buffers?

Thank you, it all makes sense now.
