Hello Tom I love these type of threads I'd like to suggest you take a look at the market and the different characteristics of each day. I would strongly suggest that Monday would be the best day for this strategy and Wednesday by far the worst. Monday tends to trend more and Wednesday = whipsaws and the like. If someone could provide me with hourly FTSE data I'd be very happy to test and tweak (hiding data to avoid data shaping) I need a strategy for the FTSE and I could give many hours to this with the right data.
This is something well worth exploring. Big Ben works best when the market has a large daily range and I will easily be able to start correlating ranges with days of the week, I just don't have much data yet on each day to be able to make a valid conclusion.
