Does my DC have full access to the code of the EA in the terminal?

[ЕВГЕНИЙ]

Greetings all!

As they say, a question for the experts!

Some time ago I wrote a certain indicator and later developed an Expert Advisor based on it.

The idea turned out to be interesting! However, I noticed that everything was working on the history and the system just stood still - the indicator almost never moved away from zero. The indicator uses several prices of different currencies at the same time - without averages, without price accumulation or anything like that. And what was my surprise when on the next day this indicator was jumping like crazy on the previous "quiet" day.

This raised 2 questions.

1) Does my brokerage company have access to the code of my EA-indicator through the terminal?

2) What happened to the prices and why they changed them in the terminal?

The indicator is not written correctly

The point is that the indicator is written correctly - almost like this one - the difference is that more currencies have been added

Are these keywords?

[ЕВГЕНИЙ]

AlexSTAL:
Are these the keywords?

in short - this indicator shows closing prices AUDNZD - in the terminal, the currency chart and the indicator are exactly the same. So, the indicator is written ABSOLUTELY correctly! No need to mince words - the code is right in front of you.

This is very important information for your dtz, especially for AUDNZD. They will do anything. You have to protect yourself somehow. Have you thought about it?

z_e_e_d:

1) Can my DC access my EA code through the terminal?

This question will not be answered here. At most you will get a banter on the subject. Think about it: for a positive answer to the question you need at least two conditions:

1) the platform must allow the broker access to the client terminal files;

2) the broker must have an .ex5 file decryptor, which at this stage of platform development only MQ could offer.

Assess for yourself how likely it is that such conditions will be disseminated upon request by the average user (even if such conditions do exist).

No one will answer that question for you here. At most, you will get a joke on the subject. Think about it: for a positive answer to the question at least two conditions must be met:

1) the platform must allow the broker access to the client terminal files;

2) the broker must have an .ex5 file decryptor, which at this stage of platform development only MQ could offer.

Another way to protect yourself is to enable encryption of the EA file (in the properties). It will not be read on another computer. You have to be careful, otherwise you won't be able to read it yourself :)

What do you mean? About encrypting the NTFS file system? If so, you are profoundly mistaken....

Stop bringing up the same nonsense over and over again.

What if they steal it? The DC probably needs this (or any other) "particular" GRAAL more than anything else...
