Hello, This might be a tough question to answer, but I thought I'd ask anyway. Does anyone have a gauge as to what point an individual would have a noticeable affect on the price of the market/instrument they are taking a position in? For example... Stock XYZ trades $100,000,000 in volume on a single day (volume X price). How big of a position would I have to take in order to actually affect the price significantly enough to make it difficult to enter the whole position at, or very near, the last ticked price? 1/10th of the daily volume dollars? 1/100th? 1/2? What do you think? Hopefully this question makes sense. Thanks!
