"Room to Add" or "Room for More"

(see also “scale in/out”) the strategy of placing a trade for only a portion of one’s standard lot size, on the idea that the price may continue to move away from target before reversing, which means an additional order will move the trader’s average entry price even further from target, resulting in either (a) increased profit when the price reverses and crosses target; or (b) reduced risk if the price ends up not reversing within the desired time frame, resulting in a stoploss.
