Subject: Re: study on execution prices by popular brokerages
This has occurred to me often; it occurred last week with APP. It occurs for me about once a month when I try to save by using a limit order. APP went from 363 to 380 the next morning so yes it can cost you if you miss a purchase by using a limit order that doesn't execute.

Sometimes the risk is big. I am up 62% in TPR in two months; if I had missed that by using a limit order trying to save 1/2%? You can see the risk.

A limit order is not a catholic wedding. Yes, maybe in 10% of trades the price will move away from you by a few cents. I always check immediately after placing my order, and I adjust the limit to get the execution. I never place an order and wait till the next day to find out that it didn’t execute.

Another 10% of the time you actually get an execution that is a few cents better than your limit.
