Mastering Elliott Wave: Presenting

Always trading with the intent of only getting in at top or bottom tick is a very dangerous habit and is not the way large amounts of money are made in this game. Profits can usually be made faster and safer when entering right before a market's acceleration phase. This usually takes place well after the high or low in the market has occurred. In addition, it is generally very important to let the market confirm (even if only in the smallest way) a change in trend has occurred before entering a position. By demanding confirmation before entering a market, you can almost always eliminate the possibility of getting caught on the wrong side of a "gap" opening. Also, if your attention is strictly focused on short-term or overnight trading, large patterns which have been forming for months or years can unwind overnight, creating panic "gap" openings

Elliott Wave can actually make long-term prediction easier than short-term prediction.

there is no limit to how large, time consuming or complicated an Elliott Wave pattern can get.
