Wave 3 was extended so we should assume a .786 extension of wave 5. ADA failed to reach this mark but we did hit the .618 level so we are well within the range to end Wave 5.
From here we could see a bounce up and reach the .786 level but it seems unlikely right now.
The Buy range
Buy range was picked because it is a very strong possibility for a bounce. .5 retracement of the entire last move up and falls right into wave 4 territory, Its almost to perfect.
