john, i’ll do some more work on this tomorrow. you were wondering why more pairs didn’t yield more pips. note that your data begins 9-08. i have almost two years more data in the four pairs. also, i had time to run my data through the same dates as you for eur/jpy. you had 913 net longs and 5375 net shorts. my data yielded 2052 and 6364. i think this is because we are looking at a different definition of “day.” Consider that our twenty-four hour periods are arbitrary. That is, the definition of “day” will depend on your platform and may give you completely different highs and lows from what I am using. I am in Chicago, central time. Oanda is on EDT and their day for me is 11PM to 10PM. The IBFX day is on GMT and that is 7PM to 6PM for me. (Hope I got that right, time always confuses me.) I definitely do not get as good results using the Oanda data as I do with IBFX.
Also, since I have data back to the '80s, I ran a quick look at eur/jpy from 1990 to the present. Longs 5831, shorts 9053. Not too shabby, but a bigger problem. The equity curve showed a tremendous drawdown right in the middle, dropping from a high over 13,000, back close to 3,000, then, recovering. Maybe that’s what they mean by, “All systems fail and usually right after I start trading them.” Have to fix dinner. Thanks for the work.
