help me please, how to save a value ?

[mrluck1]

int OnTick ()

{

if (Bid > Close [+1])

{ (Bid value saved forverer) } // How can i save Bid value that specific time?

Thanks 

[William Roeder]

1. Close[-1] is the future, it doesn't exist.
2. Close[0] is equal to Bid always.
3. Just save it (static or global.)
   int OnTick(){
     static double Bid_value_saved_forverer;
     if (Bid > Close[1]){ Bid_value_saved_forverer = Bid; }

so just put a "static" before defining double? Thanks a lot

Just 1 more question, if i put another If condition, the Static value will update if last condition is checked?  

[Marco vd Heijden]

No.

Static values are static.

If you give the static variable a new value, then it will retain that value until you assign a new value to it.

I still don't undertstand, mql4 book doesn't explain about this, and i really need to know this, for example:

 

int OnTick()

static double Bid_value_saved_forverer;

{

if (Bid > Close[1])

   { Bid_value_saved_forverer = Bid; } // happen...

   if (Bid > Close[1])
   { Bid_value_saved_forverer = Bid;} // happen too
  
   }

 

 If the first condition happen, then next happen too, the static will save only the first one, or the last?

Thanks

The last one.

const can only be set once.

If you want to remember it between calls, you can try static const 

Or look into Global Variables of the Terminal - https://docs.mql4.com/globals
