If you are playing for the long haul, limit orders do not matter. Place a buy once per month for 1/12th of your commitment, and forget about it.
For fees sure - see what fees are lowest for you (ETF vs Mutual fund). Last time I did the math for me, mutual funds ended up giving me more money in my pocket at the end of 10 years, because of no trading fees. I think if you reach a certain point in 1 purchase (100k??) ETF wins. Maybe the optimal strategy is to use a mutal fund, then when that fund hits 100k - sell it all off and put in an ETF for a lower yearly fee. Have not done the math when the exact right place to do this is, would be curious. But I know if you are doing small 400-2000 buys per month, ETF fees add up as a % of the price.
