Hello everyone, welcome back to "Thinking in Pine" short video tutorials. In this video, we have discussed special cases of using var variables inside function definitions. If you are not familiar with var variables, please take a step back and watch our earlier video - "Thinking in Pine - var, varip and regular variables" 🎲 Summary Using var within a function scope and how it behaves with multiple invocations. Using the functions containing var variable definitions within a loop. 🎯 Example Program Used Pine Script® increment()=> var i = 0 i+=1 var1 = increment() var2 = increment() var3 = increment() // The code above is equivalent to // var i1 = 0 // i1+=1 // var1 = i1 // var i2 = 0 // i2+=1 // var2 = i2 // var i3 = 0 // i3+=1 // var3 = i3 plot(var1, "Counter 1", color=color.blue) plot(var2, "Counter 2", color=color.red) plot(var3, "Counter 3", color=color.purple) arr = array.from(var1, var2, var3) for i=1 to 3 arr.push(increment()) // The code above is equivalent to // var i4 = 0 // i4+=1 // arr.push(i4) if(bar_index == 4) log.info('Value of array containing incremental values : {0}', arr) Expand 30 lines 🎲 References Pine Script® User Manual - Variable declarations Pine Script® Reference Manual - var
