I just did a cover call on THC...Sale to open. It was over $3.00. I had to trade in 10 cent increments...Fidelity would not allow 5 cent changes. I lowered the price and it got filled in 1 cent increments...Why?? Why can someone else (big boys) do those trades, but I can't? My broker explained it to me years ago, but I forgot... Is this fair???
