Hmm, what's "highlighting user functions"? I think it's all there...

User-defined function names are recognised and highlighted as "text" rather than "function".

Good afternoon, dear friends. I am having a hard time understanding the EA's optimisation parameters. I am trying to change any of the parameters in the EA properties, for example, Max drawdown, but after changing the parameter it comes back to the default value of 70. How can I change it to, for example, 30?

Enter a value, press Enter

Please tell me what I'm doing wrong.

I am making a function to change an open order under a certain condition.

I am trying to find out the current ask and bid.

В начало советника добавил

#include <Trade\SymbolInfo.mqh>

 

Внутри функции вписал:

CSymbolInfo       m_symbol;

m_symbol.Name(_Symbol);

 

Вставляю свои аск и бид через m_symbol.Bid() и m_symbol.Ask()

Но в них не текущие значения, а что-то типа «2.122011975567699 e-314»

Please tell me how to do it right.

double BidPrice=SymbolInfoDouble(_Symbol,SYMBOL_BID);
double AskPrice=SymbolInfoDouble(_Symbol,SYMBOL_ASK);

Before retrieving the bid and/or ask values in the function, you must call

m_symbol.RefreshRates();

Hello. I can't figure out how the tick indicator works. It just draws dice and then candles. Thank you

You are writing to the wrong forum. You should be on this one.

Good day all, Could you please tell me where on the site FAQ for dummies, and if not, how to put the EA on the chart window MT-4. Thanks

Regardless of the terminal version, drag and drop to the chart window.
