Using the ArrayToHex function as in the example.

AES128

It doesn't decrypt here...

I tried it a long time ago too, and it didn't work: Metatrader -> php

What if I need to encrypt in MT4 and decrypt in PHP? Is there an encryption algorithm that works the same way?

I haven't found it. Works fine MT -> MT, or php -> php. Couldn't link and gave up on the idea. It was about a year ago.

I actually found one service. Here it encrypts-decrypts similarly to http://aes.online-domain-tools.com/

If it works, and you don't mind sharing the result, write a solution to the problem

Hello !

I would like to implement an EA for placing and closing orders on graphical lines

There is a code sample available which should be based on....

If so, what prevents you from doing so? Implement it.

Alexandr Saprykin:

If you wanted to, what's stopping you? Make it happen.

Wanting and being able to do it are different )

question - how do i catch values where the line is set ?

Look it up in kodobase. Scriptor, I remember exactly, had such an example on mql5.

Glitches in MQL4 ?

for(int h = OrdersTotal()-1; h >= 0; h--)

{

if(OrderSelect(h, SELECT_BY_POS))

{

if((cnt_OO >= 2))

{

if((OrderMagicNumber() == Magic)&&(OrderLots() <= Lots/Prikup - Dplus))

{

Nextstep = NextStep;

BaseNext = OrderOpenPrice();

LotsNext = NormalizeDouble(OrderLots()*K,lotDigit);

if(NewPB > 0)

PBcloseON = true;

Alert ("Pospedny Order NEXT ",OrderTicket());

Alert ("Otkritih orderov ",cnt_OO);

break;

}}

LotsNext = NormalizeDouble(Lots*Prikup,lotDigit);

Alert ("Otkritih ordersov NEXT net ");

Alert ("Otkritih ordersov ",cnt_OO);

break;

}}

The meaning of this operation: if there are more or equal to 2 orders, the last order is handled. Otherwise, the first one will be processed.

RESULT: Otkritih orders NEXT net

Otkritih ordersov 5

Similar glitch in two other situations also with the if() operator
