trading error??

sorry, i can’t find the question right now… but like last year in level 2 (might be exact same question as they repeat), they have something about trading error and how u can make things up? (we’ll give u free research for a year)… is this actually covered in the ethics section? or is it just putting together very general concepts? ok, i see it… i’m money manager, i put in order for 50,000 shares. but yikes i put in for 500,000 shares by mistake. so my mistake… broker says he’ll eat the mistake IF you guarantee to trade aggregate 1M shares thru them in the next year. you’ve done at least that volume with them each of the last 5 years and they provide best price and execution and you have soft dollar arrangement already. … hope i paraphrased properly even though this is question from readings, when i did mock i was thinking, “how much of this is in the text??” thanks in advance!!!
