Peace be upon you and God's mercy and blessings

A person asks about
what the letters "S" or "B" that appear on the trading candle on your phone mean?
Simply put:
When you trade, whether you are selling or buying, you may notice a small letter like "S" (for Sell) or "B" (for Buy) appearing on the candlestick in your trading app.
It is very important to understand the following:
* These letters are specific to you only: this mark is a signal just for you that you made a sale or purchase at that specific point in time and on that specific candle. It’s like a reminder of your trading history on the chart.
* Not a signal for others: other traders do not see them on their screens. Each trader sees only their own marks.
* Not technical analysis: these letters are not a technical indicator used by analysts to determine market direction or make trading decisions. They are simply a record of your trades.
In simple terms, think of it this way:
As if you are placing a small mark on your personal calendar to remember that you did something specific on that day. This mark is visible only to you, and not everyone sees it. This is your personal calendar.
Why do these letters appear?
This feature helps you to:
* Review your trades: you can see where you entered and exited trades on the chart.
* Analyze your performance: it helps you link your previous decisions (buying or selling) with the subsequent price movement, which may help you understand whether your decisions were good or not.
I hope this explanation is clear and helpful!
