milan, you bring up a good point. As I've said in the thread, the "dummy" trades are a simple skeleton of a strategy. You have to bring much more to the table. For example, you may approach the day with a bias based on opening range, or based on other TA or you may do as you suggest which is to adjust risk (stop loss/size of position) depending on the choppiness of the market action. These tweaks and more, are each person's responsability.
btw GOOG and BIDU each offered beautiful dummy entries long in after hours. GOOG at $330.40 and BIDU at $68.80 [ 10 min. ]
