What you say seems very interesting to me, personally, I don't like to leave limit orders to the downside (aiming to enter low prices), because of that old trading maxim that says "Never try to catch a falling knife"; unless I am certain or have a reasonable level of certainty that there will be some kind of bounce in price (and that is usually done based on the trend).
On the other hand, what I do use is to leave limit orders to make automatic sales (that is, to make take profit). Sometimes obviously the price doesn't reach the point I project, but many other times it does, and it's a great way to automate my trading activities.
Anyway, limit orders are great, but we still have to be careful how we use them. Very good post. Greetings.
