Why do I need the “Let Panic Sell drop price to [actual buy] ХХ%” checkbox on the Settings – Main tab of the MoonBot terminal?

In the MoonBot terminal on the Settings-Main tab there is a slider “Let Panic Sell drop price to [actual buy] ХХ%” and it can vary between -40% and +5%.
This is the percentage level of the buy line to which the bot will be allowed to lower the Sell order when the Panic Sell button is pressed on the main bot window. Usually this slider is usually set in extreme left position at -40%, to give the maximum opportunity to sell the order at strong price decrease. If this slat is set at -1%, for example, and the price fell sharply by -3% and then goes downward, the Sell order will stop at -1% and will not move lower. Thus, you will not be able to sell the order quickly by pressing the Panic Sell button, and will have to waste precious time in order to close it manually, for example, already at -5%.
