Updating a Study Every Tick

The Update value intra-bar option can be found in the Properties tab when you customize the study. When enabled, it allows your indicator or study to update or re-calculate on a tick-by-tick basis. If this option is not selected, the indicator will wait to the close of each bar before updating and re-calculating.  

If you want your studies to be re-calculated after each transaction is collected, you should enable Update value intra-bar.

 For trading strategies, this option is called Generate Orders for Next Bar and is also in the Properties tab when you customize the strategy.
