Why doesn't that get me to value? Also, no errors in the compiler, but errors in MT5... void OnStart ()   {    double Close0[];    double Low0[];    CopyClose ( Symbol (), PERIOD_CURRENT , 0 , 1 ,Close0);

double b1[]; double b2[]; double b3[]; double b4[]; double b5[]; void OnStart ()   { int a1= CopyOpen ( Symbol (), PERIOD_M5 , 0 , 1 ,b1); int a2= CopyOpen ( Symbol (), PERIOD_M5 , 0 , 2 ,b2); int a3= CopyOpen ( Symbol (), PERIOD_M5 , 0 , 3

In MT5, where is the price data stored

double MathematicalAchievement = 90 ; double ScoreOfChinese = 80 ; void OnStart （）   {    if （MathematicalAchievement> 90 && ScoreOfChinese> 90 ）      {        Print

“indicator_buffers    int    Number of buffers for indicator calculation" How should understand correctly?For example, MACD indicators , we only see "MACD" and "Signal" in MT5, but why are "#property indicator_buffers 4" written

void OnStart ()   {    int symbol_0= '0' ;    int symbol_9=symbol_0+ 9 ;    printf ( "In a decimal form: symbol_0 = %d,  symbol_9 = %d" ,symbol_0,symbol_9);    printf ( "In a hexadecimal

void OnStart ()   {    int a= 'A' ;    int b= '$' ;    string c= '?' ;        string d= '\xAE' ;      Print (a,b,c,d);   }

Please, why? void OnStart ()   {    uchar   ch;       for ( char ch= 1 ;ch<= 9 ;ch++)      {       u_ch=ch;
