They are known at compile time: The color of a plot can also be determined using information that is only known when the script begins execution on the first historical bar of a chart Because compound conditions will only perform as expected if their individual conditions trigger correctly, you will save yourself many headaches if you validate the behavior of individual conditions before using a compound condition in your code. for, etc. TradingViews if/else statement: make code decisions between two options. in the same scripts visual space because RSI If we wanted to show only one level, we could use the same technique while isolating a specific loop iteration as we did in the preceding example. This gives us a general idea of the values being used in each loop iteration: We can also extract multiple values from loop iterations by building a single string which we will display using a label after the loop executes: When loops with numerous iterations make displaying all their values impractical, you can sample a subset of the iterations. Here, we explore three different techniques to inspect variable values originating from for loops, starting from this code example, which calculates the balance of bars in the lookback period which have a higher/lower true range value than the current bar: If we want to inspect the value of a variable at a single point in the loop, we can save it and plot it once the loop is exited. in a few different ways.
