TradingView UI

Why can't I find my symbols in the symbol search box?
I added the symbol data first and then the symbol descriptions. All actions were finished successfully, but the chart does not display the data. What should I do?
What if the maximum amount of time required for the symbol to appear on the chart has passed, but I still do not see it?
Would a candlestick chart be informative?
Who can use my symbols in the UI?
