You should dimension the array larger than you will ever need (and check the array bounds as you calculate them to assure that you do not exceed the size).
It looks as if the size of the price bins you are using is fixed at 1 point. If so you can use the price less the lower bound as the Index of the array. Something like the following should work:
Index = IntPortion(Price - LowerBound);
Index = MaxList(0, MinList(MaxIndex, Index));
MyArray[Index] = MyArray[Index] + 1;
