I would think you could use the same methodology. When it rises, on the first mini crash down (half way or even lower to its previous base) buy. Sell at 10-20% or whatever your target is. Repeat. Once you have a few rises and crashes you have data to look at and note how long the rises and crashes are and use that info to set your buys/sells if its a bull market. Does that make sense @quickfingersluc?
