Clickcharts no new paragraph after enter1/14/2024 The second line will plot the variable adx on the chart, however it will be plotting the previous adx, creating a bit of a “shadow” effect, that will become more clear after adding the indicator to the chart. This will plot the variable adx on the chart. The function looks like this: plot(adx, title=”ADX”, style=line, color=blue) plot(adx, title=”ADX”, style=line, color=blue) To do this we need to use the plot() function, which is actually perhaps the easiest part. Yea, its probably a tad confusing but thankfully, most of the work has been done but mathematicians or quantitative analysts and all we have to do is copy and paste! (unless you want to learn how they work which is cool if you’re into that) Plottingįinally, we’re at the end, where all the hard work comes together! We can now plot our indicator on the chart. It is set to equal 100 times the moving average of the absolute value of plus, subtracted by minus, divided sum and smoothing. The variable adx is where it all comes together. Finally, the last two variables needed are: sum = plus + minus adx = 100 * rma(abs(plus - minus) / (sum = 0 ? 1 : sum), smoothing) This is explained a bit more in the video but essentially, it is a formula not unlike those used in high school to calculate velocity. The variables plus and minus are set to equations that help create the ADX. plus = fixnan(100 * rma(up > down and up > 0 ? up : 0, length) / trueRange) minus = fixnan(100 * rma(down > up and down > 0 ? down : 0, len) / trueRange) For the sake of simplicity, you can just copy the following onto your script. We’re almost done, we just need a few more variables before we can plot our indicator. The trueRange is set to equal a built in math equation, we don’t have to worry about quite yet as its done for us. The variable down equals the negative change between the previous bar’s low and the current bar’s low. The variable up simply equals the change between the previous bar’s high and the current bar’s high. up = change(high) down = -change(low) trueRange = rma(tr, len) It is up to you to decide what those factors are and how to best calculate them, for this tutorial however we’re going to create few pre-determined variables. These are values that change based on the current price, past prices or any combination of factors. Variables are perhaps the most important part when creating a pine script indicator. This input will be used and make sense later. This input will be used to smooth the ADX lag = input(1, title=”Lag”) We have just set it to an input, with a default value of 14, with a title “Di Length.” This will make more sense towards the end of the tutorial.įor this indicator, we will need two more inputs. Length is a variable that we will use later on. Like so: length = input(14, title=”Di Length”) To create an input, we must first create a variable and set it equal to an input. Sometimes they aren’t needed, however if you like to experiment or frequently change your variables, they are a necessity. Inputs are numbers or options that will effect the output of the indicator. It is best to stick with the same name for both. You will be prompted to name the indicator again, this is the name that will show above all else, the first will show only in the chart window. After changing the text, hit ctrl + S to save the indicator. The ADX can be a very useful tool when used in confluence with other indicators. Today we’ll be creating a custom indicator called “ADX Cross” - this is based off of the “ ADX” indicator, which indicates the strength of the current trend.
