      One disadvantage of using ISLD is that partial fills are very common.If you use ISLD for a week, I can all but guarantee that you will get somevery odd fills, like 14 shares, 92 shares, or 327 shares. Although this canbe annoying, you do not have to re-enter your order. You keep your place atthe front of the line until your order is completely filled. If your brokerdealer does not offer direct access to ISLD, you can, as with Instinet,preference outstanding orders using SNET. This works. However, if yourbroker does not offer direct access to ISLD, I STRONGLY recommend that youfind a broker who does. ISLD is an incredibly powerful tool and one thatthe Day Trader cannot afford to go without.
