Tradingview Pine Script plotshape function not working with conditional series - where's the error? To show more detail, the scale in the preceding screenshot has been manually expanded by clicking and dragging the scale area. 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. The main scope are all statements that are placed at the scripts main indentation level. The plot() function has the following signature: Requires a const string argument, so it must be known at compile time. Note the last line of the whiles local block: fact.

In the scripts pane, whether your script is a chart overlay or in a separate pane. Our strategy here will be to compress and shift the TSI values For that we first make a colour variable like so: The hline() function draws a horizontal line at a given fixed price level (TradingView, n.d.). // Method #6: Change the background's color.

Some types of calls count for more than one in the total plot count. can be a literal, a variable, an expression or a function call.
