So you want to add some text to your lines in Pine Script? I totally get it - sometimes you need to label what's happening on your chart so it actually makes sense to you (and anyone else looking at it).

If you've been writing Pine Script for a while, you've probably bumped into situations where you need to keep track of data across your entire script. That's where global variables come in handy. They're basically variables that you can access from anywhere in your code, which can be super useful when you're building indicators or strategies.

Ever looked at a trading chart and wished you could just slap some arrows on it to show when something interesting happened? Well, you're in luck! Pine Script has this neat little function called plotarrow() that does exactly that.

I've been messing around with this function for a while now, and honestly, it's one of those things that seems complicated at first but is actually pretty straightforward once you get the hang of it.

So you're working with Pine Script and you've heard about this thing called "offset" but you're not quite sure what it does? I get it - when I first started messing around with TradingView indicators, offset seemed like one of those mysterious features that everyone mentioned but nobody really explained properly.

Let me break it down for you in simple terms.

The na() function in Pine Script is one of those things that seems simple at first, but it's actually pretty important once you start building more complex indicators. If you've ever wondered why your script crashes on certain bars or why some calculations just don't work right, there's a good chance it has to do with missing data - and that's where na() comes in handy.

You know what's really cool about Pine Script? You can make your indicators super flexible without forcing people to dig into your code. Input options are basically your way of saying "hey, want to tweak this setting? Just use this slider instead of editing my script."

Let me walk you through how this stuff works - it's actually pretty straightforward once you get the hang of it.

So you want to know when a new trading day starts on your charts? Maybe you're building an opening range breakout strategy, or you just want to get notified when the market opens. Either way, detecting the first bar of each day is super useful in Pine Script.

Ever looked at a chart with multiple lines and thought "man, I wish I could just shade the area between these two lines"? Well, you're in luck! Pine Script has this neat little function called fill() that does exactly that. It's honestly one of my favorite features because it makes charts so much easier to read at a glance.

Ever wanted to draw lines on your TradingView charts to mark important levels or trends? Pine Script makes this pretty straightforward with the line.new() function. Whether you're trying to spot trend lines, mark support and resistance, or just want to highlight something interesting on your chart, drawing lines can really help you see what's going on in the market.
