Computers don't randomly forget values. If you save the value in a static variable or a global variable then it will be saved from one tick to the next. The data will get lost if the terminal is shutdown but then you could save to a file. I suspect that the simple option of using a static variable will be enough.

Try this:

if(save_my_high_value)
    GlobalVariableSet("high_last_10", iHigh(Symbol(),PERIOD_H1,iHighest(Symbol(),PERIOD_H1,MODE_HIGH,10,0)));                  

//...
// later on, ... You can even shutdown the terminal.

double the_highest_bar = GlobalVariableGet("high_last_10");
if(Ask>the_highest_bar) 
  do_something_with_it();

You don't need global variables or statics (persistent storage)

im trying to find high and low of the last 10 bars then keep the value and wait until the price cross it up or down

int start(){
    int     iLL =  Lowest(NULL,0, MODE_LOW,  10, 1),
            iHH = Highest(NULL,0, MODE_HIGH, 10, 1);
    double  LL  =  Low[iLL],
            HH  = High[iHH];
    if      (Bid > HH){ ... }
    else if (Bid < HH){ ... }
    // else return and wait.
