Pyramiding

Pyramiding (in TradeStation) specifically refers to adding shares/contracts to existing positions within a market using multiple entry orders in the same direction. You specify whether or not your trading strategy can add to existing positions, and if so, under what circumstances. Please note that this is different from an alternate definition of "pyramiding"  that involves using unrealized profits from one securities or commodities position as collateral to buy further positions with funds borrowed from a broker.
