Questions from Beginners MQL5 MT5 MetaTrader 5 - page 1070

erotin:

I used the following class
CTrade m_trade;
and the function
m_trade.Buy
I used to get these annoying requotes, especially in multicurrency, even on demo server, despite all sorts of dancing with RefreshRates, slippage, the problem did not disappear.

Then I have moved to the
CTrade trade class;
and a function
trade.PositionOpen
I have not seen any requotes anymore. Maybe it can help you too

These are different methods of the same class. You haven't moved anywhere:)

It's just that the PositionOpen method requires to set parameters of the position to be opened, while the Buy methodopens with the set parameters by default. That's the difference.

Don't get in the way. The circus is gone and there's nowhere to go.

To solve this problem: right-click on EURUSD in "Market Watch", select "Symbols Ctrl+U" in the context menu, then click Create Symbol and fill in the fields Symbol = USDEUR and below the field Synthetic Instrument Formula = 1.0 / EURUSD , then OK - OK, in the "Market Watch" window the USDEUR symbol will appear

Thank you.

Too bad you can't trade them.

to trade them.

or codes that can be plugged into my owl.

I don't need a mirror quotes kind of thing.

You need a synthetic.

You have been correctly answered: "flip the EURUSD".

And if you don't know that it's not possible to flip the monitor without using an indicator, but mathematically-programmatically, it doesn't give you the right to be rude to people - the problem is your lack of understanding.

Is it a shame to ask stupid questions under your own name?))

I wanted to spread the classes across 2 inludes, but I can't get rid of the problem of usingenum in both .mqh files

there's file 1.mqh:

enum        ENUM_DEAL_TYPE{NONE,BUY,SELL}
class A
{
        ENUM_DEAL_TYPE type
};

and file 2.mqh:

enum        ENUM_DEAL_TYPE{NONE,BUY,SELL}
class B
{
        ENUM_DEAL_TYPE type
};

When I attach it to the main code, I get an error

enumeration already defined 2.mqh

see previous declaration of'ENUM_DEAL_TYPE'

as far as I understand the "Conditional compilation (#ifdef, #ifndef, #else, #endif)" directive is needed - never had any experience here, hard going ((
