hi; a question about time define in mql5 .

New comment
 

hi ;

i want to check market by candles are in special time,

for example:

day_of_week==2
Hour_Start=20;
Minute_Start=0;
Hour_End=23;
Minute_End=59;

with using :MqlDateTime

     MqlDateTime time_now;
//   TimeCurrent(time_now);
     if( time_now.day_of_week==2 && 
        (time_now.hour>=Hour_Start &&  time_now.min>=Minute_Start ) && 
        (time_now.hour<=Hour_End &&  time_now.min<=Minute_End )        )

can you explain to fixed.

thanx

 

Why do you comment TimeCurrent function call?

You need to use some time function to get time. Try TimeTradeServer

 

thank you.

i correct it but ; still has a problem;

there is no change in color for  :

day_of_week==4
Hour_Start=6;
Minute_Start=0;
Hour_End=23;
Minute_End=59;

pic. :







 

The time is never larger then 23:59...

day_of_week==4
Hour_Start=6;
Minute_Start=0;
Hour_End=23;
Minute_End=59;
if( time_now.day_of_week==Day_End && time_now.hour>=Hour_End &&  time_now.min>=Minute_End )

It means:

if( time_now.day_of_week==4 && time_now.hour>=23 &&  time_now.min>=59)

this condition true only 1 minute at day4 23:59. after 1 minute the time will be day 5 0:00, therefore 5 !=time_now.day_of_week and 0!>=time_now.hour and 0!>=time_now.time

 

Please write when do you change the color.
 

TIMisthebest, I'm not so sure what you are trying to achieve, are you trying to change candle color for specific time ?. If yes, then you can not use ChartSetInteger() function, because this function will change the color off all candle. You also have to change your code. Below is modified code, base on Heikin Ashi.

with thank to phi.nuts ;( & how helped;)

thank help.

i want to draw candle in chart with my favorite color ; assume:

1)  in case normal: 

input color Color_Chart_Line_0=Magenta;
input color Color_Candle_Bull_0=SkyBlue;
input color Color_Candle_Bear_0=LightPink;
input color Color_Bar_Up_0=PowderBlue;
input color Color_Bar_Down_0=Bisque;

then for special time ; for example : (  " 3hour before market closing " or " 3hour after market opening " , { to see in tester;,,,, and with expert use this  indicator ; the market reaction ,)

for simple this : assume;

2) when time between :

int Day_Start=4;
int Hour_Start=6;
int Minute_Start=0;
int Day_End=4; // 
int Hour_End=20;
int Minute_End=59;

the color change to :

input color Color_Chart_Line_1=Red;
input color Color_Candle_Bull_1=Red;
input color Color_Candle_Bear_1=Red;
input color Color_Bar_Up_1=Red;
input color Color_Bar_Down_1=Red;

make it visible on the CHART with different color.

in this code:

but still has problem ; can you please check it

You don't have this

#property indicator_color1  Yellow, DodgerBlue, Red, Green

in property.

This is my modified code from above - I'm not so sure if it is correct

no it is not correct;

with change in day and time ;

the candles dose not change in color

 
TIMisthebest:

no it is not correct;

with change in day and time ;

the candles dose not change in color

Good then, you can begin re-writing it, and I can correct it if you want.

After all you're the only person who knows what you want.
