The first example is hyper-compression of fractals from the younger TFs climbing on top of each other within one or two bars of the current TF. It is clear that this is visually unreadable and should be filtered out. The second variant is quite decent (only fractals of the current TF and higher remain).

Something is broken in the 540 build - judging by the feedback(http://forum.fxtde.com/index.php?showtopic=2747&view=findpost&p=34925) simple recompiling did not help.

I got it working at some brokers myself, one broker

Is it on the last build?

Also provide the build number of the tester agent.

In general, you should contact Service Desk with such questions.

Write to servicedesk. Attach expert, optimization settings, input parameters, server where optimization was done + which agents were used.

If there are any logs left, please include them as well.

Is there an error in this code? Expert Advisor is multi-currency. Prices are fine for the currency pair I ran it on, but for other pairs something strange happens with the prices.

They are either there or not. If the tester loads data in a normal way, in its logs there are the following strings

And if the first test normally passes and data are loaded, the second time no prices. History for symbols has been loaded, the Expert Advisor has been run multiple times. What should be done to check that data is loaded for the symbols other than the one tested in the expert?

I have noticed that the second initialization fails if I terminate the test after a successful start. If you close the terminal and open it again, the first run will be normal. If I don't interrupt the test and re-run it, I get error "no prices for symbol" again

Konstantin83:

I have noticed that if after a successful test run, interrupted, the second initialization fails. and the third and fourth. If you close the terminal and reopen it, the first run is fine. If I don't interrupt the test and restart it I get error "no values for symbol" again

Where and how is MarketWatch generated?

As far as I understood, this block tries to add a symbol to the list and check the result.

   if (SymbolSelect(Exp_Symbol, true))
    {
     Print("Символ " + Exp_Symbol + " выбран в окне MarketWatch.");
    }
   else
    {
     Print("Произошла ошибка при выборе символа " + Exp_Symbol);
     GetMyLastError(GetLastError());
    }

But if the Expert Advisor is a multiline, it means several currency pairs should be added (the above example does not show that).
