There are several reasons why take profit (T/P) and stop loss (S/L) price levels may not be displayed on your chart:

Chart settings:
The chart settings might not be configured to show T/P and S/L lines. Check your MT4/MT5 settings under "tools" - "options," navigate to the chart tab, and ensure that "show trade levels" is enabled.

Price distance:
If the T/P or S/L levels are set far from the current market price, they may fall outside the visible range of your chart. To view them, try zooming out, switching to a larger timeframe, or adjusting the chart price ratio to see a broader price range.

Product mismatch:
Ensure that the chart you are viewing corresponds exactly to the product you are trading.
