Custom Indicators vs Public Indicators: Which Should Traders Use?
A public indicator is one that anyone can find and add from TradingView's shared library, and a custom indicator is one built or adjusted to match your own rules. On the chart they behave the same way, plotting lines, shapes, or colors on your price. The real difference is fit. A public indicator is made for a general audience, so it might use settings that don't match how you trade. A custom indicator starts from your exact idea, like a specific moving average length or a condition that only fires under rules you care about. Public is faster to try. Custom takes a bit more effort but tends to line up with what you actually watch. Neither one predicts the future. Both are context tools that describe what price has already done.
A practical comparison of building your own indicators versus using public library scripts, including transparency and control tradeoffs.
Key points
- A public indicator comes ready made from TradingView's community library, so you can add it in seconds without building anything.
- A custom indicator is built or tweaked around your own rules, which usually means it fits your chart better than a generic one.
- Both types plot the same way, and neither one can tell you what price will do next; they only describe what has already happened.
- Public indicators are great for learning a concept quickly, but their default settings are made for a broad audience, not your specific plan.
- Custom indicators take more setup, and the payoff is that every line and alert reflects a rule you chose on purpose.
- You don't have to code from scratch to get a custom one; you can describe the rules in plain words and have them turned into a script.
Frequently asked questions
Are custom indicators better than public ones?
Not automatically. A custom indicator fits your rules more closely, but a well made public one can be just as useful if it matches how you trade. Better usually means better fit, not fancier math.
Can a public indicator be turned into a custom one?
Yes. If a public indicator is close to what you want, you can copy its logic and change the parts that don't fit, like the length, the colors, or the condition that triggers an alert.
Do I need to know how to code to make a custom indicator?
No. You can write custom Pine Script by hand, but you can also describe what you want in plain language and have the script written for you, then paste it into TradingView.
Why do two indicators with the same name plot differently?
Usually because their settings differ. Two RSI scripts can use different lengths or smoothing, so they draw slightly different lines even though they share a name. Always check the inputs.
How do I make a custom indicator inside Agenticks?
You can ask the AlgoAgent to build one. Describe the rule you want, and the agent generates the Pine Script you paste into TradingView, so you get a custom indicator without writing code yourself.
