Here, we plot high and low pivots using a line, but we do not want to plot anything when a new pivot comes in, You can also use conditional colors to avoid plotting under certain conditions. We use the ? : ternary operator to write our conditional statement. We define a c_ma color variable that is assigned one of our two colors, depending on the value of the maRising boolean.We define an maRising boolean variable which will hold true when the moving average is higher on the current bar than it was on the last.We provide users of our script a selection of colors for our bull/bear colors.Int lengthInput = input.int(20, "Length", minval = 2)Ĭolor maBullColorInput = lor(een, "Bull")Ĭolor maBearColorInput = lor(color.maroon, "Bear")Ĭolor c_ma = maRising ? maBullColorInput : maBearColorInput Build new colors dynamically, by calculating them as the script executes bar to bar, to implement color gradients, for colors", "", true).Use conditional statements to select colors from a few pre-determined base colors.For those cases, programmers have two options: Or when the script begins execution on bar zero. Sometimes, however, colors need to be created as the script executes on each bar because they depend on conditions that are unknown at compile time, The colors in the previous script do not vary as the script executes bar to bar. This is also true for other functions with a transp parameter. Which entails it must be known before the script is executed, and so cannot be calculated dynamically, as your script executes bar to bar.Īdditionally, if you use a color argument that already includes transparency information,Īs is done in the next three plot() calls,Īny argument used for the transp parameter would have no effect. Using the transp parameter to define transparency is not as flexible because it requires an argument of input integer type, This use should be avoided as the transp is deprecated in Pine Script ® v5. The last two plot() calls specify transparency using the transp parameter. All five methods are functionally equivalent: In the following script, all plots use the same color.oliveĬolor with a transparency of 40, but expressed in different ways. This table lists their names, hexadecimal equivalent,Īnd RGB values as arguments to color.rgb(): Name There are 17 built-in colors in Pine Script ®. Strategy(), you can control the relative z-index of plot*(),įill() visuals using their sequential order in the script. Note that by using explicit_plot_zorder = true in indicator() or So background colors are always at the bottom of z space, and tables will always appear on top of all other elements: This list contains the groups of visual elements, ordered by increasing z-index, So a plot can never appear on top of a table, for example, because tables have the highest z-index. Each group has its own position in the z space, and within the same group,Įlements created last in the script’s logic will appear on top of other elements from the same group.Īn element of one group cannot be placed outside the region of the z space attributed to its group, Elements with the highest z-index appear on top.Įlements drawn in Pine Script ® are divided in groups. The z-index is a value that represents the position of elements on the z axis. When you place elements in a script’s visual space, they have relative depth on the z axis some will appear on top of others. Pine Script ® has built-in colors such as een,Īs well as functions like color.rgb() which allow you to dynamically generate any color in the RGBA color space. The only exception to this rule is that a pane indicator can color chart bars or candles. The color of bars or the body of candles appearing on a chart.Ī script can only color the elements it places in its own visual space.The background of a script’s visual space, whether the script is running in its own pane, or in overlay mode on the chart.Any element you can plot or draw in an indicator’s visual space, be it lines, fills, text or candles.The 4,294,967,296 possible assemblies of color and transparency available in Pine Script ® can be applied to: Using colors in Pine can be as simple as you want, or as involved as your concept requires. Good visual designs establish a visual hierarchy that allows the more important information to stand out, and the less important one to not get in the way. Well-designed plots and drawings make indicators easier to use and understand. Script visuals can play a critical role in the usability of the indicators we write in Pine Script ®.
