I want to display the highest price 'among the candles I am currently viewing' like picture above.
I created the indicator by entering the code exactly as the link says, but nothing happened. What's wrong?

Here is the code i used.

Hello hybinubt,

MaxValue would not be used for that purpose, you need to loop over the bar data and find the maximum bar price. You can see a sample of looping over the currently visible bars and getting prices here:

The Print also will not appear in the chart, that is a debugging tool that sends the text to the NinjaScript output window.
