I have been back-testing the system’s outlined in his book and with channel breakout’s it is relatively easy, but with trend analysis and the conqueror it gets tricky depending on what time you plan to enter and exit the trade. Enter on next day close vs enter on next day open and vice versa for exiting trades and to top this going back for 4 years and doing this for multiple currencies is very time consuming. I will most likely force myself to back tests the methods though just to gain extreme confidence in the systems and not to question myself whether they work or not. Whether I try them on all currencies, well I doubt I would go that far. The conqueror is a pain to back-test!
Also in reply to your taking a break, it may be good if your feeling like the system doesn’t work during this market, actually according to my back-test his methods did extremely well in 2008 and 2011 was one of the worst years (my entries may differ than yours).
The problem I have with it is that Smith’s systems are built on massive hits, not hitting singles with >60% win/loss ratio, if you miss one or two of these during the years it can have a drastic effect on the system results. For example in 2008 for eur/usd with the channel breakout alone I believe my back-test produced over 2,000 pips for the year, yet 1,000 of them came from a single trade!
Let me know what you think of all this
