I have a question here that I'm hoping someone can answer. I am fairly new to this and don't understand why I often get "partial" fills. They almost always fill 1/2 of my order - no matter how many shares I'm wanting.
And, yes, I'm always below ask but is there a rhyme or reason to this? If I want 10k shares, should I put in an order for 20k so I'll get what I want? (Edit: Ok, I know this doesn't make sense, but what I'm asking "is there a strategy to combat this?")
This may be investing 101, but I just haven't figured it out yet.
