Scale order
An order type in which the instructions contained are to buy shares in increments as the price decrease or increase. A scale order is done by dividing the total number of shares to be bought into increments and will be executed at a price set by the investor. For example, if an investor has intentions to buy 100 shares of stocks and uses a scale order, every $1 drop in price will buy 20 shares and so on until 100 shares are purchased.
