How to turn positive number to negative number vice versa? I created indicator when EUR is down it means the USD is up, I computed the price in EUR/USD.

Just use a minus sign.

    int myVal1 = 4;
    int myVal2 = -myVal1;
    int myVal3 = -myVal2;
    printf("myVal1=%+i myVal2=%+i myVal3=%+i",myVal1,myVal2,myVal3);

if you just want to turn val to a negative val

val=val-(2*val);



if you want to save the original val... 

val2=val-(2*val);
