By the way, in the wake of yesterday’s “tip”, another tip to avoid such parentheses issues and save you time not having to find the problem and solve it: typing the start of the keyword (for example “aver” for average), and clicking in toolbar on the yellow lightbulb, it will propose all language keywords with “aver” inside, then click on the one wanted in the list and it will complete “aver” in your code, in this case “average[20](close)”, now that syntaxt is ok, replace 20 if needed, replace close if needed.
