Deming Replied: At the end of the second bar, x=2. The number of ticks
which make up the bar have no effect on the calculation. The variables (X)
are updated on the final tick of a 5 min bar.

First you must turn on "Update Every Tick" then it will process your code on
every tick of the bar. There is no easy way to detect what tick (first vs.
second) of bar you're on. It can be done using Global Variables or HashNums
products. You can learn more about these products at:

These products allow you to perform intra bar calculations. For example with
your example, X would equal 100 if the 5-min bar consisted of 100 ticks.
