Want to fill myArray with a certain value after an event. So far either
increments or just places zero. The goal is to take the value of the previous
myArray value and place it in the current myArray value. Want it to continue
until value changed. Hope this is explained reasonably.
While in Commentary / Interpration window it might be slower. But don't want
to use loops in backtesting etc.
Your assistance is appreciated!
myArray[0] = 3.0;
myArray[1] = 6.0;
myArray[2] = 9.0; //I want to fill myArray with the last entered value
"BarIndex() = " + WriteVal(BarIndex()); //To show index only.
printf("Before If statement: myArray = %f\n", LastValue(myArray, False));
if(LastValue(BarIndex(), False) >= 2)
{
myArray = Ref(myArray, -1); //commented stuff is same result.
//myArray[BarCount - 1] = myArray[BarCount - 2];
//myArray[LastValue(BarIndex())] = myArray[LastValue(BarIndex()) - 1];
printf("\nInside If statement: myArray = %f\n", LastValue(myArray,
False));
printf("\n");
}
printf("Outside If statement: myArray = %f\n", LastValue(myArray, False));
