The commission cost does not even have to be high. I just set my limit price and let it sit there all day, filling 100 shares at a time, whatever. Commission cost: $9.95/day, for whatever number of days is required to trade the total number of shares desired.
Finally an honest person on these message boards. Same thing with me. I only do mental stops now but still sometimes it happens. I think the real money may be made by being very patient (like 10 years)with a core holding. Consider it like having silver buried in the back yard. It is so much easier to click a mouse to sell rather than get a shovel and dig it up and then find a buyer. If that was the case we would rally have to be sure we had to sell. That is probably the way we should hold a basket of silver stocks and physical. Hold and wait for a mania.
Don't use stops on thinly traded securities like MGN, the market maker will ALWAYS screw you. Use mental stops. MGN also has a large spread compared with other securities IMO, so that's a double no no. Ditto for market orders.
