This is for exchange traded instruments. Use OrderCalcMargin

how do I go from margin to lot if the margin per lot is zero?

bool  OrderCalcMargin(

   string                symbol,           // имя символа

Error on account switching with different symbol names.: Bild 2300

Suppose:

There is an account with all symbols without a suffix ! e.g. EURUSD

Installed Expert Advisor, everything is OK:

everything works.

Then we change the account without such symbols, but with another one with the suffix !

No chart is loaded, Expert Advisor is not initialized. OK

I.e. EA does not show life. OK! There is no chart!

We change the chart to another one (drag and drop the symbol in the window) The chart is built, but EA does not call the OnInit() function

Even OnTick does not work after these actions. I.e. the EA is dead, although it shows it is there!

Checked it on MACD Sample - the same thing.

The same is in build 2308.

Although I was wondering whether it is important to fix it. what percentage of those who will change accounts with different pairs and do as i did. ?

But just in case, I'll throw it in my profile. Otherwise I'll forget.

I remembered they wrote about this mistake before. I didn't know what it was. Now I've got myself in trouble. Better try to fix it though.

For all that.

Communication problems, SL/TP close to the market, broker spoiling, and a million other reasons.

I haven't noticed any problems with the connection, SL/TP are not close to the market at all. The broker cannot be spoiled because it is a MetaQuotes-Demo. Accordingly, there could be far fewer than a million reasons.

[Igor Zakharov]

Alexey Viktorov:

got it... calculate the margin per lot using this function, that will be the answer...

[Andrey Khatimlianskii]

Alexey Viktorov:
I haven't noticed any problems with communication, SL/TP is not close at all. The broker cannot pamper because it is MetaQuotes-Demo. Accordingly, the reasons may be much less than a million.

In MQ such errors can be emulated for testing purposes. Re-quotes (long enough) and disconnections are also common.

This is not worth paying attention to.

I don't recommend checking the strategy and hoping for results from this server.

This server is more of a bug test server.

And this delay happens often.

Sometimes it takes 5 to 10 seconds for positions to open. Especially if it is a permanent opening (we try to test it that way).

This is not a broker and it's not obliged to provide the conditions.

Better to open cent accounts to test and more or less understandable results.

Do not pay attention to it.

Thank God it's not an MT5 error. I didn't pay any attention to it before. Now I just happened to see such figures.
