HOW-TO apply an indicator that is only available upon request?

2023年11月30日

Recently, I've realized that my typical day involves constant encounters with indicators. For example, when the alarm clock rings, it's an indicator that it's morning and time to get up. I am checking the phone and once again paying attention to the indicators: battery charge and network signal level. I figure out in just one second that such a complex element of the phone as the battery is 100% charged and the signal from the cell towers is good enough.

Then I’m going out on a busy street, and it's only because of the traffic light indicator that I can safely cross the road to reach the parking lot. Looking at the on-board computer of my car, with its many indicators, I know that all the components of this complicated mechanism are working properly, and I can start driving.

Now, imagine what would happen if none of this existed. I would have to act blindly, relying on luck: hoping that I would wake up on time, that the phone would work today, that car drivers would let me cross the road, and that my own car would not suddenly stop because it ran out of gas.

We can say that indicators help to explain complex processes or phenomena in simple and understandable language. I think they will always be in demand in today's complex world, where we deal with a huge flow of information that cannot be perceived without simplifications.

If we talk about the financial market, it's all about constant data, data, data. Add in the element of randomness and everything becomes totally messed up.

To create indicators that simplify the analysis of financial information, the TradingView platform uses its own programming language — Pine Script. With this language, you can describe not only unique indicators, but also strategies — meaning algorithms for opening and closing positions.

All these tools are grouped together under the term "script". Just like a trade or educational idea, a script can also be published. After this, it will be available to other users. The published script can be:

1. Visible in the list of community scripts with unrestricted access. Simply find the script by its name and add it to the chart.
2. Visible in the list of community scripts, but access is by invitation only. You'll need to find the script by its name and request access from its author.
3. Not visible in the list of community scripts, but accessible via a link. To add such a script to a chart, you need to have the link.
4. Not visible in the list of community scripts; access is by invitation only. You'll need both a link to the script and permission for access obtained from its author.

If you have added to your favorites a script that requires permission from the author, you'll only be able to start using the indicators after the author includes you in the script's user list. Without this, you will get an error message every time you add an indicator to the chart. In this case, contact the author to learn how to gain access. Instructions on how to contact the author are located after the script's description and highlighted within a frame. There you will also find the 'Add to favorite indicators' button.



The access can be valid until a certain date or indefinitely. If the author has granted access, you will be able to add the script to the chart.
