Note that you don't have to make a chart yourself. If you need trading ideas, you can visit the "Ideas" section of the site and see what others think about the development of a particular company or currency. Here are the community's opinions on various markets, from currencies to the stocks of major companies.
Trade ideas are created on their own accord. Anyone who thinks they can contribute can post their work to present it to the community. TradingView has done a great job towards providing the community with quality content, it is probably one of the few places to find good quality free content, if not the only one.
Note that once a graphic is published, the picture is not editable. In this way, you can compare how much a particular idea has been implemented as planned. This should not be used to prove that one author is better than another, but to learn and adapt to market sentiment.
