I was wondering at what lot size did people seem to start having difficulty getting consistant fills with and only getting partials. For example a 10 lot may get completely filled 95% of the time and a 30 lot may get completely filled 85% of the time. DO you also find it easier to get reliable fills on size with market orders or limits. I know there is not an exact definite answer to this question. I am just trying to get some opinions from other YM traders.
