I wonder if you can help me. Please. I am afraid to do something wrong.

When you register a real account, you have registered a personal account on the DC website, you can change your password there.

Or call support and they will tell you everything.

Please advise how to implement

Lots=NormalizeDouble(AccountBalance()/CheckLots,2);

Rounding down, i.e. if AccountBalance()/CheckLots = 0.019

rounded to 0,01

Vitaly Muzichenko:

Take a lookat this.

Solved the problem in a different, simpler way I think.

NormalizeDouble rounds 0.5 to 1 and 0.4 to 0 The solution is

Lots=NormalizeDouble(AccountBalance()/CheckLots-0.005,2);

• MathFloor

[Vitaly Muzichenko]

Airat Safin:

• MathFloor

returns the integer numeric value nearest to the bottom.

Is 0.01 an integer?

Can you tell me how to implement

rounded down to 0,01

Lots=NormalizeDouble(AccountBalance()/CheckLots,

2); => int    Digits = 2                         ;
    => double Power  = MathPow   ( 10 , Digits ) ;

    => double Lots   = MathFloor ( Power * AccountBalance / CheckLots ) / Power ;

int OnInit () {
Print ( "==================================================================" ) ;

int    Digits = 2                       ;
double Power  = MathPow ( 10 , Digits ) ;

double AccountBalance =  0.19 ;
double CheckLots      = 10.00 ;

double Lots1 =                       AccountBalance / CheckLots           ;
double Lots2 = MathFloor   ( Power * AccountBalance / CheckLots ) / Power ;

Print ( "AccountBalance= " , AccountBalance ) ;
Print ( "CheckLots=      " , CheckLots      ) ;

Print ( "Lots1=          " , Lots1          ) ;
Print ( "Lots2=          " , Lots2          ) ;

Print ( "==================================================================" ) ;

Another question

   ObjectSetText("Lev",StringConcatenate("Lev: ",DoubleToStr(MarketInfo(Symbol(),MODE_STOPLEVEL),0)),SizeINFO,"Times New Roman",InfoColor);

How to set font thickness FW_BOLD

I'm afraid I won't understand it in words.

P.S. The MQL4 Reference didn't help(.

This issue has already been resolved

Attempt number 2.

Please help, it seems like a simple question.

ObjectSetText("Lev",StringConcatenate("Lev: ",DoubleToStr(MarketInfo(Symbol(),MODE_STOPLEVEL),0)),SizeInfo,"Times New Roman",InfoColor);

How to set font thickness FW_BOLD, or rather how to relate to

TextSetFont( "Time New Roman",9,FW_BOLD,0);

I am afraid I won't understand it in words.

P.S. The MQL4 Reference didn't help(.
