What is the SellSpreadDistance parameter responsible for in the “Sell Order / SellSpread” tab of the strategy settings in the MoonBot terminal?

In the MoonBot terminal, on the Sell Order / SellSpread tab of the strategy settings, the SellSpreadDistance parameter is located: place a Sell order below the top of the spread by a specified percentage. The value can only be negative from -1% to -100%.
For example, the spread is 5%, SellSpreadDistance = -10%, then the Sell order will be set at 4.5% of the top of the spread (abs. 5% spread ratio). 10% of the spread = abs. 4.5% installation of a Sell order).
