Here I would like to sum up all the ideas I talked about in the preceding threads, and come up with a conclusion. The system will weigh pre-open range, pre-open volume and weekday, estimate whether today is a range or a trend day, and then trade accordingly - within support and resistance on a range day, and beyond such levels on a trend day. Look at the attached picture and tell me if it makes sense to you that on a given day an intraday system should be permitted either trend or range trading and never both. According to this concept, this week would have seen trades within support and resistance on thursday and friday, and trades beyond S & R on the first three days of the week. (That is, it would have done so provided that the "pre-open weighing" method worked and predicted correctly which were trend and range days). On the picture, you see daily candlesticks of the Dow Jones for this week. You can also see "micro-seasonality" at work. Just as August and December, also Thursdays and Fridays tend to be range days, and they were on this occasion. By the way, it can't be seen in the picture, but this week confirms my assertions and tests that say that the larger is the range on a day, the larger is the volume (it happens on monday, tuesday, wednesday). Also, I have verified once more that pre-open volume is directly proportional to the final daily volume, and that the pre-open range is directly proportional to the final daily range. In other words, the "pre-open weighing" method predicted correctly the whole week.
