Last week was super painful for the markets, but there was a shining light. Goog managed to hold some of its gains from the previous week and not retest its lows. This seems to be a good sign for the stock so i figured I would do a bit of charting. here is a long term view of the stock with the Fibonacci retracement lines drawn in. Notice how the stock tells us that these points are important by gaping over the lines or bouncing off of them.

Finally here is the same graph just with an optimized simple moving average cross over. The computer says that the best entry point, assuming no costs is when the 4 day moving average cross above the 47 day, and the best time to sell long is when the 14 day crosses below the 59 day. Over the period this netted 101.5% return on trades compared to 53% change in price that buy and hold would have achieved.
