idealing has a widget that allows you to enter orders into the level 2 order nook, so i can buy from people selling at bid price (my bid price) however havent had a sale yet - i need to practise!!
the aim is as you said to flog it back on the offer asap :)
but - im competing with other direct market access folk and the MM's and yesterday they kept upping my bid, so i never got filled...
but will try more in new year
off tomorrow to bangkok then hong kong - back in new year
