The show_last attribute iq trade room displays the last N bars for a plot, where N is an integer. The following script shows the last 20 open values in circle style. In the following script, we offset the green close plot by -10, moving it 10 bars to the left. The history-referencing operator allows you to fetch previous bar values.

Make sure you save backups of your scripts in case something goes wrong, or you need to make modifications. The first step in creating an indicator is to define your inputs. Inputs are the parameters of an indicator that can be adjusted by the user.
Unlike most other programming languages, where a code snippet is a standalone entity, a Pine Script code is applied on each bar or candle stick in your chart. The code runs in an unseen loop that iterates through all the bars in your chart, performs a calculation, and returns a value. The purpose of Pine Script is to create custom indicators, strategies, and trading alerts to maintain an advantage over other investors.
Learn its cloud-based convenience, robust analysis tools, and automation capabilities.

There is a plotchar() function that allows you to plot ASCII characters on your chart.
If you have never worked with data organized in series before, you will need practice in putting them to work for you. In this case we have the ta part of the function call and ema() which stand for Technical Analysis and Exponential Moving Average, respectively.
