Juer:

Thank you, could you please specify which property function to use? I only see OBJPROP_LEVELCOLOR, OBJPROP_LEVELSTYLE, OBJPROP_LEVELWIDTH and the number of levels OBJPROP_LEVELS. For the first three, a modifier is given to indicate the level number.

By the way, I tried to change the colour of one Fibonacci level, it changed the colour of the whole object:

Where name is the name of Fibonacci Retracement object.

Why did the colour of the whole object change?

It works for me.

   ObjectSetInteger(ChartID(), "FiboLevels", OBJPROP_LEVELCOLOR, 0, clrBlack);
   ObjectSetInteger(ChartID(), "FiboLevels", OBJPROP_LEVELCOLOR, 2, clrGreen);
   ObjectSetInteger(ChartID(), "FiboLevels", OBJPROP_LEVELCOLOR, 4, clrYellow);

Why has the colour of the whole object changed?

this is the mt4 branch ;)

Why has the colour of the whole object changed?

and does it work in the tester in visual mode too?

[marga.mitr]

Downloaded and installed from manufacturer's website MT4, opened properties and unblocked as recommended before installation, but cannot connect to desired brokers

Works in MT5, not tested in MT4.

It's because of people like you that the SD was shut down. You probably have advanced dementia!

It's a pity servicedesk didn't post application feats on the forum, it would have been fun to read them ))

Alexey Viktorov:
Works in MT5, not checked in MT4.

So this is an MT4 thread...

orena:
Finally, can you tell me how to connect my real account to mt5? When I contact technical support they reply that for technical reasons mt5 is temporarily unavailable. It can't be the same?

And this mql5 site is a bit confusing... Wanted to correct information in my profile - no changes saved. For an answer here, on the forum...

Is there any normal explanation for all this?

Thank you in advance for any possible information.

Are you sure your real account is open for MT5? The thing is that MT5 and MT4 real accounts are different. You need to open a real account for a certain terminal.

If in the MT5 terminal you can't connect to your broker's server (not detected), then most probably your broker does not support MT5 (it happens).

After changing the information in your mql5 profile, at the very bottom of the page there is a window where you have to enter your password from your account and click the button "save" below. then changes you made will be saved. (Just yesterday did so - everything is OK.)

Hello. Trying to figure out encryption. Can anyone encrypt with MQL4 and then decrypt with some web service? I get the result in MQL4, but I can't decrypt it with the same key (outside MQL4).

For example https://www.devglan.com/online-tools/aes-encryption-decryption

My key seems to be too long here. But I can't decrypt it with the right key too...

Using the ArrayToHex function as in the example.

It's not decrypted here...
