With my current size this is a nonissue, but hope to start increasing size with some new strategies. I have noticed though in the YM and especially in the TF that you can have for example 25 sitting in the bid or ask, but most trades that hit are 1-3 lots. After these hit many times the market moves pretty fast and you may not see that price again. I was wondering if there are 25 sitting in the ask and I hit it with a 25 lot order am I going to get filled on all 25, or with how HFT programs work, are the ask orders going to get pulled after the first 1-3 go through then the market advances to make you get in at a worse price.
Not criticizing your choice of instrument, just curious.
