You trade in the MoonBot terminal on the USDT pair and see the arrow from the parallel BTC pair, which appears paler on the chart. To avoid confusion, make these arrows from the parallel pair (BTC) paler in Settings – User Interface – Color Setup or change their color a little to distinguish the chart of the parallel pair.
If it bothers you, you can disable the display of trades in the BTC pair, by right-clicking on the “Show Spot trades\OrderBook” button, which is situated to the left of the “Funnel” button, and uncheck the “Show BTC Trades” option in the menu. But it’s better not to do it, because the shoots at the parallel trading pair can be a hint that the buyers and sellers are still fighting and the price at your pair can still grow, at least to the level of the shoot.
