Thank you

1) this 

int candle;
bool bear, bull, neutral, Candle;
   if(Close[1]<Open[1]Candle= bear;
   if(Close[1]>Open[1])Candle= bull;
   if(Close[1]==Open[1])Candle= neutral;// the previous candle type, I have to setup the time initialization next

   return(candle);

belongs in the section start

2) int candle; cant be bear, bull or neutral

3) u need to check if there is a new bar If not, you will get a file in size u cant imagine

4) what for u need the int i;

 

Hi

It will be the previous bar, will set this to perform the check at 2200 gmt and then it will check the type of candle the previous bar is (Close[1])?

So it will save in the file what the candle is that closed at 2200.

I am not sure about the int i; as I am new to coding, I was wondering if I can have some help with this?

Just wondering what this means: "2) int candle; cant be bear, bull or neutral"

Thanks

Antony

 

I have moved:

int candle;
bool bear, bull, neutral, Candle;
   if(Close[1]<Open[1]Candle= bear;
   if(Close[1]>Open[1])Candle= bull;
   if(Close[1]==Open[1])Candle= neutral;// the previous candle type, I have to setup the time initialization next

   return(candle);

no u don't

i said to start section & not to start of the file

 
  1. exactly
  2. bool bear, bull, neutral, Candle;
   if(Close[1]<Open[1])Candle= bear;
   if(Close[1]>Open[1])Candle= bull;
   if(Close[1]==Open[1])Candle= neutral;
    equivalent code:
    bool Candle;
   if(Close[1]<Open[1])Candle= 0;
   if(Close[1]>Open[1])Candle= 0;
   if(Close[1]==Open[1])Candle= 0;
    maybe you want an enumeration, something like
    int Candle;  // INT not bool
   #define bear    1
   #define bull    2
   #define neutral 3
     if(Close[1]<Open[1])Candle= bear;
else if(Close[1]>Open[1])Candle= bull;
else                     Candle= neutral;
