I don't try to predict when. I generally know if it's going up or down and approximately how far it could go before it meets support or resistance but, as far as time goes, I've seen it happen fast and fall that much in one day and I could show you examples of that but, this board does not allow the mention of another chart symbol even when it's for the purpose of illustrating a point. I've also seen it happen slowly. Since this market tends to move more slowly I would guess that it will continue at it's current pace with perhaps just a bit more momentum. That is to say that markets usually go down faster than they go up. If you look at the wedge (chart below) you can see what might happen in terms of days and still be within the confines of the wedge.
