At face value, some ‘professional’ traders appear to be motivated by taking advantage of a number of current market practices which encourage high volume day trading, such as tight spreads quoted by liquidity providers; the commission rebates offered by issuers to brokers and which are passed on to these clients; and the readiness of some brokers to charge low commission rates or to allow clients to trade unlimited quantities of derivative warrants for a fixed nominal commission payment.

表面看来，部分“专业”交易者进行买卖的目的似乎是为了想受惠于现时多项鼓励大量即日买卖的市场作业方式，例如流通量提供者所报出的狭窄差价；发行人向经纪行提供的佣金回扣会转而令该等客户受惠；及若干经纪行-5愿意徵收较低的佣金率，或容许客户在支付定额的象徵式佣金后不限数量地买卖衍生权证。
